I have a 2010 VW Golf TDI 2.0 CJAA engine. Can OBDeleven prime both lift pump and aux boost pumps simultaneously to prime/bleed the fuel system? If so how do you do it?

Bump for this. How's about some support? Pretty basic procedure...

Yes it can. I did mine. Can't really remember the steps to do this. I will connect my device when on my break and get back to you

This porcess sounds like you want to flood the engine during cold starts.

Hi all, just got my Obdeleven Pro, nifty bit of kit. I'm looking to do a fuel filter change on my mk6 golf 1.6 tdi. Just want to make sure i can prime the fuel pump after with this. Is it just like the steps davidtdi has set out in the above post ?
Cheers
Sime

I've never worked with a diesel vehicle before in such a manner, but the process seems plausible.

Thanks Matthew, hopefully someone on here can chime in who's completed this process on a diesel
Cheers

On my 2011 touran 1.6 tdi i changed the diesel filter and did it this way
Go to control module 01 (engine) , function 04 basic setting, channel 35, aktivate
The fuel pump runs then for round one minute and fill up the filter system with diesel.
Works fine on my touran

Works fine on my touran Thank you very much Daniel, can you adjust the length of time it primes the system ? I saw a youtube vid, where it says to run the pump for 30 seconds & do this 3 times, but this was with VCDS. Is Obdeleven a similar process ? Your help is very much apreciated Daniel. |

Its the similiar process. I do not remember how long the pump runs. It was may a minute, i did this 2 times to be sure that everything is fine

What are you not able to do? Can you choose the channel or what did not work.

It wouldn't let me run the fuel pump, came up with some error. Just gone into the history and i get this.
Basic Settings
Control Unit
(01) Engine
Basic settings
Test of auxiliary fuel pump
Status
Not active
Exited due to reasons of safety
i did exactly the same procedure as this, although this is for the mk7, i presume it is the same process

Ok ,when i did it at my car i dont have these charts i only had channels. I would say transfer fuel pump. But when i had to choose i would test both of them

Hi Daniel,
When i tested the auxilliary fuel pump, it wouldn't activate and said something like " exited due to safety reasons"

Mhh may some other here could help. What is with the other chart? Did it start?

Mhh may some other here could help. What is with the other chart? Did it start? That is the screen i got when i clicked on basic settings in engine control module. I ended up filling the canister with diesel manually. It took a few attempts to start the car after this. I may just end up investing in VCDS as Obdeleven doesn't look like it will work in this particular scenario, don't know why ?  |

Ok. I hope you will not get any damages at the high pressure pump from common rail system, these pumps are very sensible for running dry. Its a known vw problem with these pumps. Hope you got luck, because when you fill up the canister manually there will be air inside fuel pipes. Thats why you need to start a few times before engine runs. Hopefully you will get no problemns in a few or thousand miles.

Regaards What do you mean " hopefully no problems in a few or thousand miles "  Are you saying i've damaged my high pressure pump from cranking the engine a few times until it started ? |

The problem is that the high pressure pump is really susceptible when it runs dry, means if pump runs a few seconds without fuel its possible that little little pices/chippings rip of from the pump. Then it can be possible that the pump gets destroyed , or dont can give enough pressure or little chippings get to the injektor. It can happen in few miles in few thousand miles or never. But the fact is that this pumps really sensible.

Hope somebody can help as to why Obdeleven failed to run this procedure on my car.. very dissappointed with the device at the moment.
Do you know if it's safe to try and run this procedure without changing the fuel filter, just for the purpose of testing ?? If so, i would have done this prior to changing the fuel filter, just to see if it worked.

There must be no risk to test it with no changing, priming the fuel pump just fills up the diesel line and filter, when the lines are full with diesel it just goes back into the fuel tank by using the return line.
May there is a way to prime the pump by making a bridge at the fuel pump relais.

I think i may have sorted this, i tested it again last night but clicked on the " tranfer fuel pump " (FP) test, and it seemed like it activated it, a little red hand appeared at the bottom of the screen with the words "stop" to exit the test.
Does this seem right to you guys ?

Yes this is correct. But you dont need to tap the stop button after i think round one minute it stops by itself.

Just a quick update, i changed my fuel filter this morning, and once complete and all buttoned up i activated the " transfer fuel pump " in basic settings, i ran it twice and VOILA !!! Worked perfectly, it fired up with the first turn of the key and ran perfectly. Thanks for all your help Daniel......
