I usually go Febi-Bilstein for decent quality.

 

You could try GSF and ECP. They do ecom as well as in person sales.

 

Great thanks for your replies, I'll take a look at them.

 

That first code suggests the cam timing is off - not a faulty sensor. The incorrect correltion betweent he cam and crank usually means a skipped chain or ,possibly, a stuck timing variator, but that usually give a set-point code instead.

The second one is quite possibly a wiring issue too. A better scan tool, like VCDS etc, would generally give you more details, like "open circuit", "Short to ground", "Implausible signal" etc. If it's "sporadic", i'd have thought a wiring issue more likely.

Check measuring blocks and see what its reads. Same with the timing - was specified vs actual for the cam timing. If it's skipped the chain, you may get no reading at all.

 

Came here to say about the cam timing.

It's what mine showed on the generic reader, but on VCDS one block was totally missing.

 

Ok, thank you both for the heads up. I will get it checked out by someone.
