[quote=MikkiJayne;118912]Yes, one per bank, but the ECU knows which cylinder it just fired so it can work out which one just knocked as well.
There are measuring blocks for individual cylinder knock detection parameters iirc so you can watch it running and see what is happening, and plot it on a graph using VCDS. Swap the coil pack and / or spark plug to another cylinder to see if it moves.[/QUOTE
aha BUT
looking for parts it seems there are what are called blue sensors and green sensors ...presumably should be the same on each bank?
if I read this correctly the problem can be either
spark plug , coil pack OR knock sensor ?
tks MJ
