    Shifter Locked Out - Multiple Codes/Symptoms All At Once

    Driving to scoop up dinner I had these new symptoms:
    o PRNDS all highlighted
    o Oil Sensor Warning
    o AC/Climatronic no power

    Car seemed to drive normally (not in limp mode for sure), shifting as expected.

    Before I shut the car off trying to move the shifter to Park it locked itself in Neutral and wouldn't move. I was able to shut the car off, put key in the ACC position (the click before 'On') and move it back to park.

    New Codes from scans (all new from this symptom):

    80-00 - Single-Wire Operation
    00562 - Sensor for Oil Level/Temperature (G266)
    30-00 - Open or Short to Plus

    I checked all fuses, found a 15A in position 33 that seemed in dubious shape (top by numbers was distorted from internal changes) so replaced that. Also found one of the smaller 10A fuses in position 5 that was visibly broken as well, so also replaced that. Locations based on this chart:

    https://fusesdiagram.com/audi/fuses-...udi-a6-c5.html

    Tested again with new fuses, no change.
    Cleared codes, no change.

    It feels that based on the large count of things that all happened at the same time I might be hitting a single point of failure but couldn't track down any good info on what (if anything) interconnects those items that are showing shorts (Climatronic, Transmission brake switch N110, Oil Sensor).

    Any ideas? Thanks in advance
