There should be another code for between D and 4/S. And a 4th code for 4-3 and 3-2 if have that available. So we do now know that those intermediate positions exist and are recognised by the TCU, though not if it does anything (or what) as a result. This could be the basis of another useful diagnostics test on the F125, moving the shifter slowly and monitoring the TCU. Where exactly in VCDS do you find those codes?

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": Quote:

I wonder what Craigs TCU was seeing when he had his gearbox problems, maybe also Z1?
Bearing in mind it was his problem/question that caused this thread to be initiated. Good to see he's got it going now, but I did struggle to understand what the initial problem was. It looked like it was something really serious but I think it was just that "P" wasn't illuminating on the DIS (though everything may have actually been working) which was down to a shifter cable adjustment. This highlights a couple of things, firstly that the two sides of the F125 really are electrically/electronically independent and work very differently and secondly that mechanical devices can work incorrectly but be sending valid signals (at the wrong time) so often no errors are logged by the IT kit.
