No, it _doesn't_ help, Steve.  It confuses me still further.

Your "early MC" cam (034 109 021K) is the one used in the MB engine - yet
another data point taking the MB (single knock sensor) closer to the
MC-1 (single knock sensor) and away from the MC-2.

Can it be that my suspicions were right all along - and I have the same
_cam_ as well as the same _head_ in my 1986 Passat?
