A VERY good Video. I don't have the year or model, but i am looking how to use VAG COM to run the pump on a 2001 A4. This video is precise, well explained, and short. Great Job.

Another good video Chitty, the forum has gone crap since you sold the forum, the TDI Wiki link doesn't show now

Thanks for this information.

I didnt know there is a 2nd fuel pompe (auxiliary fuel pump) could you give us it OE or OEM part number so i could do search ? many thanks

Thanks a lot for your perfect video. Could you please precise me the gauge used for each cable?

Hie , got a Vw Touareg r5 TdI, my problem is last week the fuel station guys put diesel that was contaminated with water, after driving for a few kilomtres, the car stated misfiring and some jags then it stopped, i tried to crank it then it started aftr few seconds of idling it cuts off,we checked the diesel in the filter thats when whe saw that there was a mixture of diesel and water, so we drained all the diesel in the tank and cleaned the tank and also cranking to clear everthing in line from tank to the diesel filter, then we put new diesel n new filter, but nw the car is only cranking without starting, wat could be the problem guys

The CAN protocol is unavailable to me, I only have UDS, so the "Meas_Block" option is also unavailable. I do not understand. I have a VAG of 18.9 and the car is a Passat b7 (2011 year)

I have the latest VCDS installed, when i go to basic settings there are only options in a pull down list, I am not able to type in group 35. So my options are not the same. Any advice?

If your just changing the fuel filter (black cartridge) a simple way to do this is to just prime to filter itself. I used a small 1 litre utility pump with a nozzle that fit into the spout on the side of the filter. Started up straight away easy money , no mucking around taking out seats or anything like that 😊

Hey where did you order your cable from? ive been looking at amazon but people saying cable ont work if you run windows 7 or 10 off your laptop. Its for my 2012 Volkswagen Golf TDI 2.0L Wagon

Do you know how many pumps the 1.6 TDI 2011 has? If I turn on the ignition, on my 1.6 TDI 2011, I do hear some noise from the area where the pump at the tank is located... What pumps, specificly, are you activating when running the VCDS, for priming?

I diagnosed faulty injector on 1.6 tdi engine in 2016 octavia via leak off test. Fitted it. Coded it in and now it runs terrible. Injector brand new so highly unlikely its that. No codes at all. I'm hoping because I've had pipes off theres an air lock and this will fix it. Any help appreciated!

If you were to manually bleed the air out using a vacuum pump like a Mightyvac, which of the four hose(s) at the fuel filter would you need to disconnect and plug the vacuum pump into to draw out the air? This would be on a 2012 mk6 Golf. I’m assuming you would disconnect the braided cable that goes to the HPFP and clamp that closed, and then connect the vacuum line to the port on the fuel filter and draw in the fuel to the vacuum. Does that sound right?

@dominicfynn506

Or actually would I need to hook the vacuum to the fuel return line (back to fuel tank) which would draw fuel from the tank and filter and then into the vacuum which would ensure the filter is full with fuel and no air?

Hi my high lift pump went on my 2011 jetta had to change everything i didnt do what ypu done by priming the pump i just primed it turnning the key few times now my auxiliary pump next to the fuel filter under the bonnet is making a humming noise does anone know why its doing this

this wont work for the high pressure lines into injectors correct? the hpfp wont push air out of injectors?

Do you know if Volkswagen TDI engines have a water separator?

How about with the updated VCDS software? Mine is from 2022 and there is no way to get to 035… Ideas?

I thought there is only one electric fuel pump in the back of the car. The high pressure pump is mechanical, isn't it? Using VCDS 17.8.0 I could only activate that one in the fuel tank.

After changing the fuel filter i cranked the car 10 times and got it started, then drove 10km and guess the fuel system is air free..... Did not know about the vcds methode....I will get me a vcds next time

My passat 13 only has a pump in the tank i did the procedure and still the same some times works and sometimes shut off

Randomly my 2014 3.0 A6 tdi misfired on startup as if air got into the fuel lines. Restarting it a couple of times and letting it sit for a few minutes resolved the issue. Curious what it might have been. It just happened one time without anything notable surrounding the event. I replaced the fuel filter with OEM a couple years ago.

My mechanic tried to start the engine normaly after fuel filter change but it didnt start. Then he remembered that it had to be done via the pc. Do you think that 2 or three times 6-8 seconds tryes he did that the hight pressure pump had any damage???

Yep, VW have changed the software again. You can run the low pressure pump but the high pressure pump can'r be operated. Just prime using the LP pump and then try a start. It will crank a little longer than normal then fire. No real prob if you've tightened everything right!

There is a much easier way without VCDS than your hard way. There are two relays for the fuel pumps. The relays are located below the dash board. You have to remove the cover to access them. The relays are labeled 404 and located at place 4.1 and 5.2 (side by side). Remove and jump them. For daredevils like me, a paperclip does the job :-)

I tried doing this on my 2013 Passat. My VCDS software was a little different - latest version. Under basic Settings I didn’t have the option to type in group 35. I only had a drop down list and the only fuel related options I could see were the initial fuel fill and the transfer pump test. I did the transfer pump test 3 times but it still did not start. Any suggestions? (I was replacing injectors - got two replaced but the other two were stuck so I was trying to restart the engine to see if a heated engine would help to get them loose)

No use basic settings then both pumps run for over a minute. Repeat 5 times to be sure all the air is out. 3 times was too less on mine.

I just finished changing the fuel filter on my wife's MK6 2010 TDI Sportwagon with the type 3 fuel filter housing and did not use the VCDS. I just started it right up. It primed itself. Some diesels are self priming, some are not. Our boat has a Perkins 4-108 diesel and it will not self prime. I have to bleed the whole bloody thing or it won't run right.

The ALH TDI engines do not have an electric fuel pump. The lift pump is internal to the injectino pump.

If the system is closed how it is going to purge out air if trapped during fuel filter change :?

The fuel pumps always supply more fuel than needed. Otherwise the engine could starve of fuel. Excess fuel pumped to the engine is sent back via a fuel return line.

Starting from the fuel pickup in the tank all the way to the engine there should be no air in the lines, but the tank has air in it. Air purged will go to the tank.

An informative video but VCDS from RossTech is not a viable option for DIY considering the cost of VCDS compared to a single car fuel filter change. Ours is a 2011 Polo TDI BlueMotion (cfwa CR engine). Does anyone know the manual way to run both pumps to bleed the fuel line? I've read that if the fuel line is not adequately bled, the result is permanent damage to the injector equipment.

OBD11 is less expensive than VCDS.

on a duramax first you need a special tool called a hand, which you use to press the primer on the filter housing. Then it's done. why they have 3 pump is bullshit, at most you need one lift pump to feed the main high pressure. I will stay with the BRM and older volks diesels. The new gen has very bad injection pump design that eats itself up.

Just because some of you have started you cars without priming the system does not mean its an OK thing to do. You could very well be damaging your hpfp (you know, the one that uses fuel for lubricant) every time you do it. It may not fail the first time, but when it does fail it will be very expensive to fix. Quit being cheap and buy a VCDS cable if you are going to work on your car. Or find someone that has one and is willing to share. There are plenty of those guys out there.

How does manually turning on the pumps with a vcds differ than cranking? Either way, air has to pass through the pump to escape. Please explain.

What are the consequences if i would happen if I place a rag with gasoline at the end of the air filter basically to jump start the car when it has an air lock like this?? Because that turns it on and you can skip everything you just did.

also can send metal shavings from the hpfp through the fuel system causing 8k in damage because the fuel pump had nothing to lube it

The "easy way" is also the ridiculously expensive way if you don't already have the super expensive software and licensing to use it.

Oh my God! If I had known it would be so involved for such as simple thing as running out of fuel, I would never have bought a VW TDI... Running out of fuel is extremely common in the real world. VW needs to figure out how to deal with that in a simple way. Like with gasoline engines... I have regretted getting this TDI a few times due to fuel availability during long trips.

Here is yet another way to prime both pumps at the same time WITHOUT VCDS: kzread.info/dash/bejne/mJNkl7GCgMzViNo.html

So when you use the vcds program somehow the air magically disappears? And it's not being purged by the pump? This makes no sense. When you use the vcds or crank, your pump is still purging air the same exact way... Meaning the air is escaping VIA pump. No matter the method air will pass through the pump to purge it. Explain in detail if I'm wrong. Otherwise clean the housing, fill the housing half way with diesel slowly lower the new filter so the filter is primed. Screw the top back on and let her rip.

Maybe you figure it by now, but the idea is to not run the high pressure fuel pump without fuel. The Bosch CP4 has already a poor design and like to grenade itself from time to time, running this without fuel can destroy it because a cam inside the pump is lubricated by fuel. Of course, this being on the timing belt spins when the engine is spinning so that's why you need to prime the system with a diagnostic tool.

There is a 10000 times easyer way!!! Just take off the air filter housing and blow brake cleaner in the tube going to engine while somone else is trying to start the car. Keep blowing brake cleaner until the engine keeps running whithout it trying to fall still. The air will go away whitin 2 minutes. And you can also avoid air in system by filling the fuel filter completly with fuel before starting that will prevend air getting in system
