I'm curious, trying to pinpoint my p12a1, already did coils, sparks, fuel filter and lpfp..... Before I install the next 200 buck item (hpfp) I want to know....

In vagcom when I log 106 it shows in neutral 40bar requested and actual. Duty is still 60%. When I rev it to 3k Rpm should requested increase with actual ? They are staying pretty much 40-42bar.

I can drive it around, it smells in cab and outside... Smells "off" , not right.

I'm afraid to drive it to work to get codes to possibly come back and have to get towed home again.

I just found a technical bulletin of how to test the n276 valve and if it doesn't click to replace the hpfp... Been at this for a week and half, please help, thank you.

Is the LPFP dealer or aftermarket?

Log 230 and 231 instead of 106. Watch the specified and actual there when you rev it to near redline in "P" or neutral if MT.

Is P12a1 the only code you've seen?
