@Dan_FR What are fuel trims exactly if its not too complicated to explain? What I just posted are the fuel trims, correct? I just logged block 32 when idle after driving for a bit. Didnt clear any DTCS. Are they not normal? Sorry for my lack of knowledge - LTFT? realtime - so log as im driving?
@doylebros its looking likely the PCV bolts are the issue considering what dan is saying. Unfortunately easier said then done, I tried to use a borrowed set of easy outs but they were way too big. I think I either need to find a smaller set of easy outs or get a dremel cutting disc to cut a groove in it, but the shaft is fairly set back into the rocker cover. Ive been thinking about a small clamp instead possibly.
I dont really understand how the intake cracks would affect it, there are small holes in the air box cover anyway? Perhaps ill borrow my mates whole engine cover and try that. assuming a leon fr bwa is the same apart from the VW/Seat logo
