Last 7 digits of the VIN? Ill look up functional description and pin assignments and ill inform/advise you.I need to know what particular DME system (M62/M62TU) production date may also be useful.M62TU uses a pigtailed knock sensors (2 sensors/1 connector) 1 on each side.Hoping you have a multi meter or your "mechanic" has some kind of scope you can determine the root cause.Have you physically looked at the DME connector(s)? Recheck the connector by unplugging it and looking at the pins making sure none are bent/misaligned/or corroded.I believe #4 is the drivers side rear (closest to firewall).F.Y.I. Bank 1 is passenger side (always the one with chain tensioner) cylinder 1 or 5 is closest to front of car.I will wait for the info and get back to you.
