« Last post by MKVASMR on Today at 09:46:16 pm »I had the same issue a couple of weeks ago. Checked the DV, PCV, N75 Valve, checked the fuel trims (hoses etc…). Ended up being a cracked turbo exhaust side. It was a hairline, but after replacing it all was good. Not saying that that’s the issue in your case, just something to be aware of. Start by checking the boost hoses, if they are oily it could mean that here is a leak. Specially where they connect to the intercooler. Next I would check the DV and after that the PCV. If you have a way to log the MAF, do that and multiply the g/s (I think) from engine live data, channel 02. Should be around 160 I think. Is the car tuned? It can throw the same fault code when it’s tuned. But if it goes well I wouldn’t really give it much attention.
but looks great so far. Tubing is as close to the chassis as possible, welds look beautiful and the bends are super smooth rather than sharp and weak. Still lots to do of little jobs but the big job is done, need to start working out my paint strategy now. If I lived somewhere hot I would probably leave it as its a shame to cover up such lovely welds and beefy looking steel tubing, but as with everything here it will rust...
