Thanks for this quick and useful overview of what the N80 is and does! Even for nonspecialists like me the Bentley vid is well worth watching at least through its full, animated description of what the entire evap system does. When they got to the part about how the N80 is _pulsed_ to control how much recovered vapor is routed back to contribute to combustion, I realized why your vid included a "not recommended as a test" label at the point when you mention just hitting the N80 with 12-V dc to listen for clicks.

Thanks for your generous efforts in educating the VW owners of the world . Look forward to future videos as a Gen 6 Golf owner .

Always very informative and easy to understand - Keep up the good work!

just replaced my n80 valve 20 minutes no more hard starts after fuel fill ..tnx bro

I HAVE LEARNED ALOT FROM CHARLES. I CAN TOTALLY UNDERSTAND WATCHING HIS VIDEOS, AND HE EXPLAINS VERY WELL. AWESOME! AND TO ME,,, THE BEST!

still a very helpfull video , this fixed my P0441 fault code on a VW Golf mk4

Hey bro thanks for these videos you have showed me and helped me understand so much about vw parts

That was super insightful and very well presented. Thank you!

Hey back again. Just went outside and checked the wiring connection to the purge valve and bang its working correctly. Loose connection. Thank you for that comment you said about wiring in this video made me check it again to be sure.😁👍👍

This video is a gold!! So much useful information is shared in such a short period of time! All is clear, gives nice recommendations and explains potential problems caused by the failed purge valve. I do get several errors from the OBD tool, which I am leaned to connected with this failed part. Will give it DIY try. Thank you so much for the video, @HumbleMechanic!

very informative, working on a 2007 a4...looked at the famous n80 valve but the culprit ended up being the leak detection pump...when testing between terminals 1 and 2 there was no continuity. thanks!

thanks for the info , your videos are awesome and informative

I'm just about a minute and a half into this video and you made me feel crazy old! LOL! you mentioned the "Way Old 1551" ! When I was a tech at VW, that was our scan tool. Ha Ha Ha! I always like your videos. Thanks for making them. Since I've been out of the tech game since 2000, you help me with repairs I do at home. Cheers!

Very useful info. Thanks Charles!

very helpful DIY information. thanks.

Very helpful. I have a P0441 code (Incorrect purge flow) on a B5 A4 and was reading from a lot of sources that it could be the canister. I'm happier knowing about this part as one of these from bosch is about $40 as opposed to a $200+ Canister

My Golf had the same code, changed the N80 sensor and code cleared itself.

Thanks for the video, really informative, I did it on fault code p2188 on Kia Cerato/Forte 2015 along changing with O2 sensor. 🙂

Nice 1, Charles! Just had a rough idling/stalling 1.4 Mpi AUD engine. Scan brought up p1426 evap purge valve open circuit. Found electric connector unplugged there. Strange world! A lot better now, just monitoring a p0141 O2 bank1 sensor 2 heater circuit malfunction.

Thanks Charles for showing how this value functions, it's a more detail explanation - than I got from the VW dealership!

Thank You! I've been chasing a fuel rich/intermittent boost issue that was compounded by a bad temp sensor on my wife's MK1 TT for months now. It's one of those multiple problems manifesting with odd issues. I watched your video, took my N80 valve off in about 2 min gave it a sharp tap on the table and voila, gobs of powdery crap. I'm not sure if swapping it out will solve all the issues I'm having, but I'm confident the blockage is at least a compounding variable. Thanks again!

@HumbleMechanic Great video and explanation. I'm trying to test my valve but I have a 2016 Jetta with the 1.4 so it seems like the whole assymbly must be removed and not just the valve.

Hi everyone After change it, is possible the engine getting to work temperature faster than it was before ? Grettings

Appreciate this is was posted 6 years ago but very applicable now. I have 2011 Fabia TSI that has a fault when at running temperature in "coughs" intermittently at from about 1200 rpm in 4th and 5th gear, and has produced no fault codes. I have a general engine analyser that is showing 630psi on the fuel rail and goes up to in excess of 1500psi when driving. I can't get hold of what the fuel rail pressure should be. I currently working through the fuel system cleaning and checking sensors. I've just disconnected this sensor and there's no fault code shown. Any ideas, and what the fuel rail pressure should be? Thanks for the video, it's good so I've subscribed.

This was helpful, my 2014 Jetta is having this issue, but will it also cause the car not to start for about 30 at a time randomly? Or could that be another issue? Any help would be greatly appreciated

Hi mate!! Glad to see this... I have 2011 Tiguan and now it has hell lots of problem. Intake manifold was changed but still the engine light is on. Finally the dealer wants to change the salonoid sensor valve and they are charging $596 to do this saying there is no communication between the intake manifold and sensor valve. I have driven with engine light on for one week now as dealer put my appointment after 3 weeks for the sensor valve change. I felt its too expensive to repair and I am quite confuse to take it to Vw for repairs though I have booked it or to the other mechanics. Vw dealer is saying they have genuine system to diagnosis and find the fault. My question is can it be repaired outside and will it be repaired. It still shows p2015 code. Very unhappy times. Dealer is charging me $220 for parts and rest for Labour.

I had every one of those codes for the open... mine is on the way. Its a little tight on a beetle but seems simple enough to change.

Thank you for the video. My car would have a hard time starting after I filled it up and had no codes. Today I replaced the purge valve. Right after, I took the car for a test drive and notice my car was idling too low when in drive at a stop light. Can you think why this is happening? Thank you

You're the best. Any idea if there's a good indie VW specialist near Cambridge/Arlington/Lexington MA? This and other issues are piling up. I solve them very slowly myself...

thanks for your help allot

Thanks for this video, huge help understanding exactly what I'm looking at - for anyone interested my code started as P0171 (system lean) and after weeks of chasing seemingly non existent vacuum leaks the code evolved into a P0441 (incorrect purge flow)

I know this video is kinda old but if you are here for the P0456 small leak code. It is going to be your N80 purge valve its around $30 to $90. Usually Bosch is the best way to go.

Hey, thanks for this, just wondering if you can give some advice on a 2010 Polo (1.2L) that has a 4.36v on the positive side of the 2 prong connector, there is no short to ground (engine off .2v on either wire). The Check engine light is on with a P1426 code.

i have 5 codes that shoot off two for the eval, air injection relay pump- secondary, mass air flow sensor, and i dont. i have looked over your video and idk if i should also change my mass air simce i have had problem with a code popping up continuously even after i cleaned it

Charles, what's the most you think a dealer should get away with for replacing this part? Looks like a $25 part in most places, and easy to get to (2011 Jetta SE). Your opinion is appreciated.

This valve could turn on the EPC Light and the traction control and show an ESP failure? I have an Audi A6 3.2 2007

Thank you I’ve been chasing faults on faults on faults on a 2014 Jetta running multiple codes. System rich at idle, small evap leak, high purge flow. Slow leak on evap system. Been checking all evap lines & vacuum lines couldn’t find any leaks. Ran tests on the O2 sensors for the system rich issue checked out good. Cleaned the MAF sensor still having issues of the car being rich or even stalling changed the gas cap still nothing. I was starting to run out of ideas on what it could be and this could be the only logical option now of all my issues. So I’m a give this a try and hope to god it solves all my problems....

Thanks it helped me so much

Could a secondary injection fault code be because of this? It also says incorrect air flow on the code. I dont have a fancy scanner to tell where exactly the problem is.

I had this happen on my rabbit and it unfortunately did damage to the fuel pump, purge valve, gas tank, and the charcoal canister. I never got a check engine light, I found out because every time I went to fuel up it would only pump a half gallon or so before foaming up the filler neck and shutting the fuel nozzle off. Do you have any recommendation on checking the filler neck check valve to make sure it is open? I think this same issue may be happening on my mk5 Jetta now.

Good Day, as always thanks for the awesome content. Quick question. I own a 2013 VW Touareg TDiV6 180Kw. For some time now only in warm weather days the car has extremely rough idle on cold start. It lasts for about 30 seconds and then all is good. It really only happen randomly. In winter i never have the issue. Does diesel vehicles also have the N80 evap purge?

Thanks for info

Would this cause rpm fluctuations at a stop if the PCV valve/breather hose and intake manifold is good? 2010 GTI

Hi Charles from Australia. If you had a faulty purge valve that is stuck open and you have over filled your tank, could this create a situation where liquid fuel could be sucked into the manifold and then create an oil dilution situation as to excess fuel being drawn into the combustion chamber? Cheers Jeremy

I had on stuck Open on my Passat V6 30v so that every time i filled up with gas it flooded the motor Super easy and quick fix.

I have the Audi 2.0T 2006 B7 A4 and specially after refueling, any amount the car struggles a little to start back up again. Drive ability is also not as smooth, was getting P0455 evap code. Just got this part today, going to change it and will check back with results.

Had a one green check valve fail while checking the for boost leaks, that n80 valve would make a buzzing noise during 15psi boost leak check, best fix is to tune, and delete the problem entirely in states that don’t have smog checks. The fail points on modern cars are almost their demise when they are not discovered by the ECM, that valve being one especially when it comes to a fuel trim problem...

have you ever seen one of these cause a crank start issue? I have a 2002 Cabrio that has fuel pressure but the injectors aren't getting a signal from the ECM. I have replaced the fuel pump relay and the crank sensor. I have good spark, and fuel pressure, but it won't fire unless I introduce fuel directly to the intake. I'm getting a P0445, and a P2441 as well as P0418 and codes for injector circuits 1-4 "low".

Could you guys do a video on where the charcoal canister is??

My tiguan is throwing a P0456 right now. I’m away for work about 2 hours from home. Is it ok to drive home w that code before i’m able to fix it w either the fuel cap or replacing the purge valve? (if that’s what the issue is?) i have a cheaper scan tool but it did scan P0456 consistently. Just don’t want to worry too much about getting home. Thanks in advance! love your channel!

any idea on how to get to the EGR / combi valve on a new beetle 2.0l ?

Could this cause a rough idle, and maybe throw a faulty throttle body code? I’ve had a shop try and do a relearn but it’s unable to do a throttle body relearn with a cel. Have already replaced throttle body.

Great video is there anyway on the n80 purge valve for a Volkswagen Touareg you can show me the location where it is while looking over the motor.

I had P0441 "incorrect flow" INTERMITENT :) No check engine lights. There was also underboost P0299, both solved with changing the purge valve - 06H906517AA. Car is much smoother, cold idles are not rough, no missfires, and the car does not stink like hell started cold like it was before.

I need to test the purge solenoid on a 1.2 VW POLO (2011 model). Electrically it appears to be doing what it should, but when I removed the valve and tested it with a Mightyvac, the results were a little inconclusive. Basically, it will hold vacuum from the inlet manifold side, but it slowly leaks when vacuum is applied to the fuel tank side. Does this mean that the valve is good or bad? thanks.

Great channel. Thanks for posting these, I just subscribed. I have an error code P2402. The read out says "Code P2402 indicates that with the engine running above a specified RPM the PCM detected a high voltage on the eveporative emission system leak detection pump control circuit" Would the N80 trigger this fault? I have a 2012 Jetta S with the dreaded 2.0 l4 engine. Thanks again for posting these

Very informative! I have a 1998 Passat V6. Would this likely be the cause of me having the codes P1137, P0422, P1129, P1127, P1141, P1139, P0411, and P0442? I replaced the MAF sensor hoping it was the cause of all my problems but that wasn't so. It has a rough idle until it runs for a bit and tries to stall when little pressure is placed to the gas pedal. Also doesn't like to shift until 3400 rpm in Auto mode. Tip is fine. Getting the fuel pressure checked soon as well. Any advice is appreciated!

I just had this part replaced on my '13 Jetta Treadline, are you saying it is not a good idea to fill the tank in any case like mine or just if you have a fault?

I have the same problem as gotomissmars except the fueling part. I replaced the M-80 and I get the P0444 code.

Hello Charles! Am having a P-0444 (EVAP valve open) engine light. On my 2003 VW Rialta RV Euro-van. Replaced the N-80 purge valve and still get the light (even after clearing it). would you suggest checking the vent solenoid next (does it have one)? Also having problems fueling the van now. Nozzle clicks off at the pump. Feel that replacing the canister is too much for me to do myself. And want to check all my options before I take it in to a mechanic. Thank you!

Hey there! My EuroVan acts like a flooded carb engine after filling the gas tank - takes a lot of cranking and runs roughly for a few moments after it finally turns. Otherwise runs okay.. safe bet that this is the culprit?

How did you removed the filter? I'm always getting a pending incorrect flow code. How many cycles do it need before CEL turns on?

It sounds like this could cause fuel trim issues. Could it do so without throwing a code? I'm getting positive fuel trims at idle and negative fuel trims at wide open throttle. Oddly enough, my fuel trims are excellent while cruising on the interstate.

I`m currently doing some work on a 2002 Passat GLS 1.8T. One of the complaints is the CEL is illuminated. Bit of back story; I worked on this car a couple months ago with the same "EVAP Very Small Leak" DTC. Spent way to much time diagnosing it and decided to let another friends shop who specializes in VW`s have a crack at it. They also couldn`t keep the CEL off, it would always turn back on. Recently the car was brought back for another go and I decided to check the Purge Valve. We verified that the solenoid is functioning. I applied 20" of vacuum and in 10 Min. the vacuum had dropped 10". I wasn`t sure if this was out of spec. Luckily my neighbor just happens to also have a B5. I performed the same test on his N80 Valve and in the same 10 min. vacuum only dropped 2". His car doesn`t have any DTC`s. I`m replacing the N80 tomorrow with a new OEM one. I`ll post an update as to whether the DTC comes back.

Hi, I have a question regarding my 2003 golf gti. almost every day I have a stalling and rough idle/general rough running issue. I never get a check engine light and rarely it throws a bank 1 rich code. I have watched the short term fuel trim when it is running rough and stalling and it fluctuates aggressively between rich and lean state. I have replaced the MAF sensor, with a genuine Bosch part and am looking at the next thing either being the evap system or an O2 sensor... any thoughts? thanks in advance!

I'm definitely a culprit of topping off my fuel and sure enough have to have the evap changed as it has failed. Can't complain as I have 192K on my 2016 Golf.

Is there a risk of fuel tank implosion if the n80 valve is broken? I had a fault code about the evap system a few months ago and now during warm weather I can hear bubbling from the fuel tank after I've driven the engine warm. Is there any quick fixes to avoid the possible implosion of the fuel tank until I have the time to fix the issue, what ever it is? I have a 2005 Octavia II 1.6 FSI.
