Hi guys,
A month or two ago I installed an oversized ramair intake to my edition 30.
Since then I have had the occasional lumpy idle and sometimes the revs are sticking 2000 even though I am stationary. Finally managed to plug in obdeleven and I’ve got this intake leak code. I’ve been all over the installation of the intake and there is no leak from what I can tell. My understanding is that the leak must be after the MAF sensor, which is only at the turbo inlet. The intake is secured rigidly at this point so I don’t think the intake is the issue.
I’ve been doing some digging and it could be the beloved PCV, so I have ordered another one which I will replace as soon as that arrives. I did a blow test on the PCV today and when blowing I could blow through it but only a small amount, im not sure if it’s supposed to let no air through or just a little? Anyway I’m not confident that swapping the pcv will solve it so I have been doing some digging using the live data features when scanning.
I’ve read that my maf reading is peaking at around 95g/s when absolutely flooring it on the motorway I think this is way less than what is specified, so would this point me in the direction of a faulty maf now? When I took the maf out I wrapped it up and stored it safely so I am baffled as to how I may have damaged it.
The car is also running decat pipe and it may be blowing slightly...(I know right) because it sounds like crap. Would this cause the system to think it is leaking as well? I have no codes to suggest this though.
Sorry for the long post, this has been doing my head in for 2 days I’m getting ready to send it to a garage.
Edit: I’ve just done a run and monitored boost levels, the actual value peaked at 1650mbar which if I’m not mistaken works out to 24 psi minus 14.7 = 9.3 psi. Is this stock figures? Or maybe signs of a leaky DV.. SO MANY POSSIBILITIES
