HELP! I Can't Turn OFF my LIGHTS! & Cooling Fans ON Full BLAST? ('14 VW TDI)
Автокөліктер мен көлік құралдары
Owner of this hot German Hatchback says that his Daytime Running Lights stay ON ALL THE TIME...
He also mentioned that the Check Engine Light came on about the same time that the lighting problems started.
When he pulls into the shop, I noticed that the COOLING FAN was ON FULL BLAST...what the heck?
Let's see what is going on with this VW...

Maybe I'm just old, but I continue to be surprised that ANYone would purchase a vehicle off of FB market place. As best as I can tell, this vehicle had at least (3) red flags on it BEFORE he even purchased it. Some of these young guys (apparently) have no older Dad, mentor, mechanic or friend to bounce these ideas off of before getting themselves into.....this. Thanks Ivan.

I bet someone has messed with the coding of J519, that is very adjustable (you can turn on and off outputs from the ecu on certain pins) with something like Ross Tech VCDS, in the wrong hands, the coding can be screwed up. Always do a full scan prior to playing with the coding so you can revert back to the original if you screw it up. That goes for all the écus when retrofitting components like MFSW, cruise control, PDC etc. Also the cold and hot bulb monitoring can be turned off when fitting Mickey Mouse bulbs to stop the bulb error warning showing up. If you have access to SVM via the factory, the coding can be reset to the original factory coding. Another nice video Ivan.

The Pinecil is even better, basically the same iron but also with USB-C PD (it still has the barrel jack as well).
The main problem with soldering is that it makes a hardened spot for the wire to just break again right near the solder joint. So I always have a habit of tying down and securing an inch or two each way from the solder joint to ensure that it won't have fatigue breakage from movement. Of course, taped up inside a loom, you're probably not going to have that issue. Most people do take time to at least tape over solder joints, so it's normally fine. It's just the pig tails that really can be risky--- since you're wire is dangling out on it's own right near the connector, etc.. Those tend to break again. You can wrap a little splint over it with a few inches of 12 gauge solid wire (house wire) and that will keep it from bending too, if there's nothing else to tie it to. I always believed in solder over crimp--- until getting a fancy ratchet crimper that makes a perfect crimp.. Now I'm happy either way. It's kind of nice when your patch job looks like a factory crimp sometimes; I'm not against either one.
@thephantom1492
6 ай бұрын
Crimp is not better imo, it gives a pinched point where it can bend and break. The main difference is that usually crimps come with some plastic around it to prevent movement. A layer or two of good heatshrink, ideally double walled (i.e with glue) work wonder. It is stiff enough to make bending hard, and usually the wire bend after the shrink instead.

The central electric's module in these cars requires either a resistor or a correct wattage bulb to function. My friend installed aftermarket LED's in his 2008 vw r32 and it caused all kinds of issues. The module will disable circuits if it doesn't find the correct wattage lamp in the socket. Even load resistors didn't tell the computer there was the proper lamp in the socket so it would just disable it. Had thrown all of his old lamps out and had to go to the store and buy all new lamps.

These cars can be chip-tuned. Mostly done to squeeze out more horse-power. A lesser known option in these chip-tunes is disabling the bulb check. After disabling the bulb check, all kinds of cheap after-market LED retrofit kits can be used.
With led bulbs, load resistors are required to keep the PCM happy. Many people think you can install the newer bulbs without load resistors or non CAN bus complaint bulbs. With some body shops, they use aftermarket parts because of the cost of OEM factory parts due to how insurance pays, or how the quotes are done.

The problem with aftermarket parts isn't that they're necessarily bad (especially some of the more expensive Turbo kits are better than factory), the problem is they make the car unsalable at anywhere near market price since (a) most people don't want to deal with a car they can't take to the local garage (b) the guys who do want to do aftermarket changes want to do it themselves.
this is why i really am picky with after market stuff expensive mistakes happen i remember back in the day i would never plug my scanner into a Volkswagen with an aftermarket stereo because you had no idea if they installed it correctly with the proper harness and it would fry your scanner because you had high voltage where it didn’t belong if you want aftermarket stuff you need to know what you’re doing or you will get burned i personally have done some crazy after market things myself with audio i remember my installer loved some of my ideas because he loved working with relays my favorite has to be adding a retained accessories power circuit for my radio in my 1996 explorer and 1998 f150 ford at the time only had retained power for the windows at the time so it was fun to make that work without killing the gem model a couple diagrams and a relay later and boom 10 minutes of radio with the key off lol
German cars 2004> tend to have lots of customisable features built in, they can be coded with the right software, this might not be a problem it might just have been coded to stay on.
The lights can be coded for different models. The DRLs were probably coded wrong, because you can set them to European or North America DRL modes and they can be set to different percentage or dimming. I Know you can set them to come on as soon as the vehicles moves or when the ignition is set on but I don't know what or if there's a setting to leave them on. I know on some European vehicles you can leave your ambers on to park in an alley for safety even if your car is off. You can even set the fogs as the DRL and have them turn off for the blinker like we see on most vehicles now. You can't turn off the monitors of the lights for LEDs since it wants to monitor, but you can turn off the cold diagnosis.
Customer should have put it back stock. If he is going to bring the car to you for diag and repair, then he should also listen to your advice. I like the way you diagnose problems, not much gets by you !

If you swap standard bulbs for led you have to put a resistor in the line to give the load back to the flasher unit or it will run way to fast I tend to go for a 1k resistor usually does the trick but if you have purchased your led lights through a recognised seller they will generally tell you that a resistor in line is a mut
That is why a PRE-purchase inspection is vital with late model used vehicles. Any aftermarket parts can really mess up the modules and performance of the car.
I do alot of aftermarket modifications. Lesson 1: Don't buy cheap Chinesium LEDs. They will fail in a short time. Lesson 2: Aftermarket companies are not reliable in keeping track of changes inside a generation of car models. It might fit the first model in that generation but not the remaining years. Lesson 3: Aftermarket installations should be done by professionals or experienced DIYers ,that know electronic circuits and how they function.

Some VW modifiers play with module coding on VCDS/OBD Eleven thinking that they are making their car cooler. They normally forget to take a screenshot of the values before they start changing them, then they create problems. The lighting side of VCDS has loads of values that can be adjusted, for example different light intensity, different types of light systems, different country of sale, etc. I suspect someone installed those nasty aftermarket headlights, messed with the coding in VCDS to try and get a particular bulb to work, then changed the pins in the connector. When they get modified like this and they're poorly crash repaired, they are only fit for breaking/parting out, otherwise you end up with a money pit.
Just flinched when i saw those plastic coolant tubes thinking they would break when you touched them.
What goes thru a person's mind when installing a fan motor: stock or aftermarket, and leaves it wobbling. With those aftermarket lights, I was certain a module had burned internally but was thinking it would end up being an aftermarket alarm. No such luck/fun, just a regular factory lighting module - nothing to see here, move on, lol. Good vid Edit: when the customer had his knee jerk reaction that diagnostics and repairs were adding up, Im like "these things dont repair themselves - what were you expecting. Ive been following the used car market since the 80's. Used cars dont get repaired as often as they should now days because labor rates are no longer $35 an hour. We see really nice cars in the salvage yards as well as "easy" no start problems where a customer freaks out because their cars might be a few years old and simply gives up on it; rather use the money that would've gone to the dealer diagnostic/repairs as a down payment for a new car. To each their own
My wife's friend had a white '11 gti with the xenon light system. She didn't want to pay for two new $$$ headlamp assemblies after hers were cracked, so she bought two used halogen golf assemblies. I had to move a pin or two/side to get them to work. I declined to work on the noisy, soon to fail completely mechatronix. Her fan was also going to spin off and chew up wires.
Fascinating as always, since the car has apparently been crashed and repaired I had wondered if some of the loom had been replaced with one from a European spec car, one of my GM cars (I am in the UK) could be programmed to have DRLS etc. I am not familiar with the VW software but it might be an option. Cars broadly made for an international market have a lot of the lighting behaviours configurable. (Mine had settings for the headlights for Xenon, it dispensed with the CANBUS checking).
You might want to inform the customer that the computer program controlling everything doesn't have AI yet, so it can't adjust for some different loads in the wiring on its own. But those German engineers are probably working on it. So more modules might be coming. That Sylvania bulb box reminded me of when I decided to change my Expedition headlights to those brighter ones Sylvania was advertising everywhere. They are a lot brighter, but I kept getting flashed by oncoming traffic so often, that I had to go back to the factory bulb on the drivers side. That solved the problem.
I have a 2011 Chevy Malibu that started melting the wiring to the lightbulb from getting hot when the daytime running lights would activate the , the wiring can not handle the current change when dimming anymore , SO I just pulled the daytime running fuse in the fuse box , problem solved , Great video , and Led`s burn out the projectors from high heat , creating dim headlights , If you burn out the projectors , that`s the mirror finish in the headlight assembly behind the lightbulb , you will have to replace the whole thing , not cheap .
So much for after market parts ! I did the same thing with my 03 S10 SL and had to put my turn signal lights back in and just live with dim lights !
Is a TDI a hot hatchback? That's just the standard Golf (that VW no longer sells in the US). Anyway, excellent fix on this one. You made the car usable, the owner is happy.
Great cars, got an 11 sport wagon and a 15 golf both tdi, easy enough to work on and plenty of support, but you better be willing to do your own work or its going to bleed you dry.
I would like to argue that the problem is not so much the bulbs but the fact that using a bulb which uses much less current than the OEM one would make some electronic module throw a fit over it. Back when it was just a fuse and switch/relay, doing this would actually put less stress on the circuit. Diagnostics is tricky and sometimes fun (better fun to tricky ratio with experience) but I still despise the overall gadget-bloating of cars. The only parts of the car I find beneficial to manage via precise electronics are the drivetrain and brakes. Everything else is just complexity for the sake of planned obsolescence and fat repair bills while parts are still available. More work for diagnosticians that can keep up but overall completely unnecessary.
Ivan, I am impressed with your patience in dealing with this “hack job” of a car! I am surprised the owner didn’t have you wire in the DRL with an ignition power controlled relay!
My philosophy with daytime running lights is to eliminate the feature. My reasoning is they are bright enough at sunrise/sunset to "make you forget" to turn on the running light light system (tail lights....). Yea I got a could of warnings/tickets for this... This should not affect the running light system (full headlight system). I don't know the safety inspection laws in Ivan's neck of the woods, but my solution would be to keep them off. With older cars it usually involved putting tape on a relay pin (could cut the pin off... could cut the wire). From the wiring diagram Ivan showed and the looks at the connectors it looks like a no brainer. De-pin the running light left and right wire at the head light connectors. This may generate an engine check light... Again could be a problem with a car inspection. Simple symptom analysis... could be the modified headlights were drawing too much current for the running light circuit and cooked the controller.
Any chance somebody was messing around in the coding with the DRL behaviour?

Interesting... my relative's VW 5 series car have the reverse lights stuck off when in reverse gear on manual gearbox, the bulb, circuit board for bulbs in rear was ok, reverse light switch ok, wires all ok, I diagnosed the central electric module fault. Replacement of central electric module will be too expensive so the person declined it. Can always wire to the reverse light switch in manual gearbox to battery plus and a relay but the error codes will remain on dash with "bulb" warning stuck on. So some mofset in the central elec module got stuck off, there was like a voltage left of 0,7 (should be 13-14) or so in the lights when ON. OFF 0 volts. I think before this happened the person crashed into another car lightly. It also took off a red wire to ECM close to the intake manifold in front which was diagnosed and repaired, the check engine light was on, the car didnt't go on cylinder 3 error code... I am 1 years working into car mechanics and it is incredibly difficult but fun... a little stressful in the dealership sometimes.

Or better wire to the ignition switch + ON from the reverse gear switch, with a relay for safety, clamp on the reverse switch "signal" without cutting it. Then apply wire from the relay + power ON/OFF circuit to the reverse light bulb. Ground is already connected. Haven't done it... maybe in future when I have time.
I do know, that some German models, especially MB use a can system with one headlamp controls as a master to control the other headlamp.
What a mess, Ivan! Fancy add-ons worked, more or less, on non-computerized cars - now, they just create problems. Too bad customer didn't want / afford to complete the repair. Great job, anyway!
I don’t know if I picked the video up wrong but vw golfs back to 2008 have automatic lights. As soon as you unlock the car the headlamps come on. It isn’t a fault but a feature of the car. Once the key is inserted into the ignition and turned the daytime running lamps will come on: If the owner reads the owners manual he’ll find all the info in there.
Always doing what the customer wants may result in happy customers and real headaches for you. My almost 50 years experience has learned me to not always do what the customer wants.

No surprise that there would be some crossover regarding wiring diagrams but it makes no sense that the model production run would differ from country to country. The differences are quite subtle in the flesh between the 2. I would even argue the mk6 and 7 are the most similar-looking consecutive models by far on the outside and Ivan stays close to the car which makes it that much more difficult to pick out the differences. The instrument cluster is a major giveaway though. I think the mk6 uses the same one as mk5 or at least very close.

LEDs installed in other places can cause problems too. e.g., LED replacing incandescent reverse light bulb can cause strange problems on dash. Around 2007, had a letter sorting machine with strange symptoms. Looked in log book and an emergency stop switch bulb had been found dead during a monthly PM check. I didn't think that could be the cause, but following one of the key dictums in the book of tech (look where you last chit), I checked it out. Found a LED bulb. I knew they were coming to our supply (longer lasting & used less power), but that was the first one I'd seen used. Just for the hell of it, put in a regular bulb, machine fixed. Engineering put out an alert not too long later that LEDs couldn't be used in front end of these machines, only in the output sections. Lesson learned, cherche le LED! Anyone thinking of replacing an incandescent with LED better do a lot of research on that particular vehicle and that particular LED. And keep the old bulbs just in case. I just replaced halogen 9012s on a 10 year old GM with Auxito LEDs after a lot of research. Everything I read about the Auxitos on the forums was positive. It's been a month, no issues with hyperflashing, light pattern, dash warnings, no effects on other systems.

You can code the modul to know that there is aftermarket LED light on instead of the original lights you can also code every light in the car to go on and of with another light. You can also code the bulb error warning totally off just with a VCDS tester.

Great find on that harness. Those crazy lights probably cooked he module.
You can still use the led’s you just have to use resistors to make the ecu happy.. i had to do it to my truck when i switched all bulbs for leds.. it would act weird without the resistors like only one headlight would come on or the blinkers would go fast but so would the brake lights, all flashing and stuff. And the dome light would just stay on..
I am not saying that soldering isn’t a good repair the only thing is VW strongly says not to solder on there harnesses cause it can change the signals through the wires. But I know sometimes you don’t have a choice
I had issues with my dashboard on my Honda Element 6:2after replacing bulbs with leds. Some would not turn on and others started blinking like a disco. I put the OEM ones back on and issues went away. Now one of my reverse light bulbs is on its way out. I now purchased OEM bulbs and will swap the leds out. Sometimes looking cool is not always a good thing.

Too many people see LED lights online and think they would be neat to have in their vehicle - only they don't realize that modern vehicles aren't like old ones in which the car had no clue if the lights were on or not other than what the switch said. I ran into this with upgrading the headlights on my '15 Jeep. The first set that was "guaranteed to work" didn't, so I went and found a totally different company that specialized in the issue I was having and did their upgrade. I still get the occasional message of a light being out, but as soon as I turn it on (and it's working fine) the message goes away - a known issue that they are actively working on. I ran additional lights (on every rig I own) that are LED lights, through a relay, tied into an ignition switched fuse and left all my OEM wiring alone because I was afraid of the exact issue that Ivan ran into on this vehicle.
The DRL being on could be a switch in the ignition lock that detects the key being removed. I'd better check that first.
Seen shorted bulb elements cause other lights to stay on because the shorted build would find a ground through the other bulbs which caused them to light up
My guess before I watch is a shorted fan harness before the module. The ecm signal wire lol. Let's watch and see now.

A couple of things, Ivan Were you sure that when diagnosing the headlight issue you were looking at the actual OEM Volkswagen connector? At the beginning of the video you mentioned that the customer installed Xenon bulbs with an adaptor. I have a feeling you were looking at the plug coming from the adaptor. That would explain the funky pin locations. I think you should've looked for the OEM connector, removed that from the adaptor, and plugged it into the headlights to see if it fixed the DRL issue. Second thing related to DRL's, in some vehicles equipped with DRL's, you can actually turn them off if the vehicle is running, in park (or neutral for manual), and the parking brake applied. As soon as the parking brake is applied, it will turn off DRL's- at least in certain vehicles. I feel like this could've been helpful in this diagnosis if Volkswagen has their DRL's setup this way.
Great job Ivan! Some are just simple to see with a different set of eyes looking under the hood. Whoever put that front end together sure butched it up causing a lot of head aches.
You're supposed to change the long coding of the Central Electronics when you fit LED lamps in place of incandescent ones. I'm wondering if the permanently on lights are a a result of someone having a go at the coding without knowing fully what they are doing. I've read horror stories on forums of similar things happening with lights stuck on after botched coding and people having to take the car to the dealer to get the original coding reapplied. Aftermarket LED upgrades come in two varieties, ones that are just LED and ones that have resistors fitted to simulate the resistance of the incandescent filament. The latter are also known to cause issues with the electronics in some VAG models.
I know it takes a lot of character to wade thru the mods and stay on track to reach the root cause of the issues. OEM (esp on a euro car) are bad enough stock. You are a good man! This young fellow will likely lose interest and move on to something else before long.
Definitely take out the led bulb and try a regular bulb with these first. I learned that plugging anything to any module wire makes them go a bit nuts. When I installed my aftermarket fog lights I had to plug to the power just behind the the headlight to make them work with the drls. I was trying to connect to the switch on my rabbi tbefore and found those wires going straight to the module which kept giving me codes and just did not like anything there. Same with the rear camera.
I have a solution on the You can hook up all the LEDs but to get them/ 4ways to blink you need to add in an incandescent in an inconspicuous place and it will build enough resistance to make them blink
Fans on can be it doing a DPF regen. Bought a used '13 Sport wagon TDI. Brought it home on a 15° day and the fans were on when I got home. Oh crap!... Was just running a DPF regen. Whew! I wound up selling the car back to VW because of the BS 'dieselgate' and made $3,000 on the car after 3 years of use. 😁 LED 'upgrade' 🤦. Cold air intake 🤦🤦.Guys, quit reading on Internet forums...

I had a '12 Jetta TDI. Yes if a Regen failed because you shut the car off the fans would run for a while. It has to finish the regen cycle so you have to take it on the highway and drive for a while. Once the regen is done/completed its back to normal. The wife drove the car and her work was only a few miles away so not ideal for a TDI regen cycle
Really need a RossTech VCDS OBDII lead for VW group vehicles, allows settings to be changed to allow you to fit LED bulbs and not have the dash lamp out telltale light lit, you can also check DPF soot and ash loading and force a regen with it as well.

I have them both. The thinktool can do that to. You can see that in a video of Ivan. Vw touareq door module
After market garbage is correct. A friend of mine put in after market xenon bulb kit in his equinox last week. I am waiting for the eventual phone call.😄
I wonder if… the headlights were left on low beam all the time. Then after parking the module would turn them off to save the battery, and no lights would be lit. Guess it depends if the DRLs are still lit when the low beams are on…
Another brilliant diagnostic.
Great work ! As always, tracing electrical faults is a THANKLESS and time consuming job. Very informative, I'll say thanks !
I just had one of these in not too long ago, the car was leaking boost like crazy. Someone popped the radiator out of its bottom tabs and pushed it back to make room for a aftermarket intercooler. Fan cut a hole in the charge pipe.
I always cringe when I see one of those Hot Air Intake setups. Good stuff Ivan.

I think they are supposed to be a Cool Air intake, rarely give any extra power, just lot's of induction noise☹

I know they are supposed to be but there is nothing cold about the air being taken in in that configuration. The stock setup would be much more effective at pulling cooler air from outside the engine bay. @@johnbeckett2624

Ha, I thought I was the only one that called these hot air intakes since the air comes from the hot engine compartment rather than fresh outside air like stock.
A popular mod for those cars was to change out the light selector assy on the dash. But their is rewiring involved might explain why the head lights were rewired from spec
Just throwing out a wild one. Don't about if this is in the us but in Europe if you push a button at the ignition switch you turn on the parking lights. With indicator you switch either to the left or the right but i noticed with a old golf if you don't select with the indicator left or right both are lichting up. Most likely you have the same system in the us but you never know. So maybe it's an ignition switch problem.
Just add an ignition sourced N.C relay in circuit with the parking lights, whdn u turn the ignition off or parking lights on the DRLs turn off.
With the suspected front-end damage that you noted, is it possible that the headlight connectors were replaced with the wrong variant so the pinouts were close but not exact?
Looks like front collision to me. Probably was "forgotten" to be mentioned to the buyer.
My neighbor had a Golf/GTI that was a little older than this. Water intrusion into the Central Electronics Module that rotted out one headlight control chip. A used unit coded in was easier than awaiting chip shipment. If you own a VW, clean your sunroof drains and cowl drains! Leaves had built up to the point of sending water over the firewall. I've seen similar water intrusions on Beetles.

" If you own a VW, clean your sunroof drains and cowl drains!" Great advice, but VW in certain models (I believe 2016 and later) used a plastic drain pan around the sunroof, and it cracks slightly. VW's fix _in production_ was to put pieces of adhesive tape over where the cracks develop, which after 5 years dries up and you get leaks anyway.
For the daytime running lights: I’d bypass the module and put in the Russian relay controlled by ign sw. (but the cust bailed).
I know it would cost you about $45.00, but it would be nice to see a car-fax on the GTI. Would add a lot to history and entertainment.😅

It was a TDI if you look at the front logo.
Not started the video yet but head lights and fans running full blast. I KNOW THIS ONE. The harness for the Outside Air Temp sensor in the lower front left of the bumper has been damaged along with the ground wire which also services the lights, fog lights, front light washers, parking lights. Owner banged a kerb very hard, or hit a buggs bunny in just the wrong spot. Been there dont both same symptoms both times. Lights always on FANS running full blast with ignition No Air Condition No Auxilary Heat Now to see how wide of the mark my excited self is
What do you tell the cop if you get pulled over? But, officer I had to regen my DPF. 😉
The foglight. The led ones had a driver, which most likelly did not liked being PWMed. A cheaper driverless bulb would have been fine. For the module, it can be damaged by the capacitor on the input of the light bulb driver...
The problem with upmarket/sport model european vehicles youn people buy them want them to sound louder look cooler have accidents in them have a cheap repair done on them & then try to flip them because they know they will eventually have problems.VW Hatchbacks have enough problem without them having been in an accident.YOUNG PEOPLE OUT THERE BE WARNED STAY AWAY FROM THEM.Cheers Ivan great teaching video for the young un educated vehicle buyers.
Great video and the test to zero on and pinpoint the issues is simply top. Thanks though a previous benz video was instrumental in me diagnosing a draw and solve it. Keep banging out the these relevant video. Big up from jamaica.
If there is a fan fault the I highly doubt the DPF regen will run.

Coolant temp sensor fault was to blame for sure!
I know the car is hacked but you probably wouldn't want the DRLs on an ignition circuit. They probably are supposed to turn off with the headlights, and many times they also turn off when you use a turn signal to make sure other drivers can see the signal (instead of a bright white light).
I have the exact same soldering iron (even blue) and I can use it plugged in, or for portability I use it with a 6C LiPo battery. Great soldering iron.
