I have just been having a nose around with vagcom due to a suspect fault and have noticed that on group 026 the knock sensor on Cylinder #2 is reading about double what the others do. I believe this could be due to a number of problems including sensor fault/ fuel / ignition problem (I will prove by swaping them around). Vagcom is not sensing that this is a fault as it is obviously still in tolerance.

Anyone any ideas or had a similar problem??
