2005 Golf TDI not starting

[aidanbree]

Yesterday I went to start my 2005 Golf 2.0 TDI 4-Motion and it would not turn over. The glow plug indicator lights then goes out as expected and there are no abnormal warning lights. The battery is in good shape after being replaced in Jan. The engine just doesn't catch. It had been running fine and I last used it on Friday.

I saw some threads saying that it was likely to be a problem with the in tank fuel pump. So, I turned off anything that produces noise and put the key to the first stage. From the drivers seat I can hear the fuel pump moving - in fact, it almost sounds like bubbles - is this what it should sound like? I have never noticed it before - but normally I have music / aircon etc. on.

I bought one of the OBDII bluetooth adaptors a while back and hoped that it might help diagnose the issue. I cannot find any apps that will successfully read fault codes - I run Android. Is there anything app that will be capable of helping diagnose what'd going wrong?

Any pointers where I should be looking would be much appreciated

Hello it could just be a simple case of diesel run back which involves bleeding the fuel system in order to release any air bubbles trapped in the system if that does not help your issue then it could be injector related or even the fuel pump is not pumping the fuel into the fuel rail. You could try spraying some easy start into the air inlet but be sure to use a little as only a little bit is necessary to start the engine hope this helped you if not then message me and i shall try my best to help you out.

Sounds like it could be same fuel injector problem my wife had with her 2.0tdi Passat 4motion. It cost £1750 to fix, I hope it isn't this!

Really strange - I let it crank for about 30 secs and pumped the pedal and it started.

After that it has started 1st time again without touching the pedal.

The whine on the turbo seems a bit louder than I recall - not sure if this could be related?
