Title: No boost...help
Post by: poweller on January 15, 2015, 10:36:04 pm

Hi all,

Had no boost for several days now...changed DV, tested pcv...had a loom for some leaks no such luck. When i go to go in to the rev range for the turbo i hear a slight sound coming from the engine bay similar to injectors sending fuel but nothing else.

No engine management light etc...

Bump...shagged turbo?

Had a vagcom read yesterday and the only faults i got was a P1531 - camshaft timing adjustment open circuit.

And 00003 control module malfunction

Would these cause a turbo cut off?

Quite possible, yes. If the ECU can't work out what the camshaft is doing it'll go into limp mode for safety.

Brief but this is the noise revving at idle...

I would look at the N75 Valve if you have boost problems, mine went on my 1.8T and it did not show any errors at all, but they are a pig to get to on a K03 turbo.

Where about are you based mate? Anywhere near a good tuning company (AKS, AMD, R-Tech ect.)? Might be worth getting a proper mechanic who tunes these engines to have a look for you. Don't loose hope (as hard as it is when things are f**king up for you).
