Carpet and interior replaced. Manual mode not working on Auto and mystery connector

Still needing assistance on this. I’ve pulled out the center console again and don’t see anything amiss. The photo below is with the console removed showing the shifter in ‘M’ as opposed to ‘D’. It’s contacting the micro switch OK and I’ve even jumped it, but still no luck.

Actually no pic as they seem disabled in mobile. I’ll upload later

You can clear the airbag light with a Duramectric. Not sure about the other stuff. Good luck.

Following on from the GRM post, I checked my manuals and found:
"In the manual gate, the manual switch connects ground to the Tiptronic control module..."
The pinout for the TCU shows pin (13) is the manual program switch.

Got a multimeter?
One side of that switch should be ground (probably your problem spot) and the other should route to pin (13) on the Transmission control unit on the firewall in the trunk.

Need a schematic, let me know. The manual also has detailed procedure to replace the shifter unit.

Good luck with it and feel free to pm or just post. I'm watching both treads.

Before I put it all away, here's a cut of the diagram:
