F125 switch versions

[HPsauce]

Automatic Transmission (2), Measuring Block 4 and it also shows the binary 4-bit codes on the F125, exactly as I had worked out in fact.
There's a higher block (11?) that shows some of that data (and Tiptronic IIRC) but block 4 is best.

My car is of course exactly the same, only Z1 and Z2, no code between D and S.

BUT a really interesting observation! When VCDS was showing Z1 or Z2 the DIS was no longer highlighting a selector position.
It was still showing PRNDS but no red highlight until the stick moved slightly and the F125 showed a standard position.
MJ, is this what yours was doing when you struggled to get reverse or was PRNDS missing?

Edit, I think you did have PRNDS displayed, so that could indeed have been a Z1 or Z2, not a totally invalid code, just "in transit":

And in fact my initial guess may well have been correct, with a Z1 code being read:

This could have been due to shorting of the track for pin 2 to its contacts, while still having the reversing lights on.
