The Impreza got a Gearbox and Rear diff oil change yesterday - absolutely no idea when it was last done, but the magnetic bungs did not look concerning  

I have the same three codes. Did you find a solution? What was the answer?

The TT guys I know pretty much all reflash with internet ROMs until they find one that works.   I know a TT running a G4x and still TT.

Like nominally yes, but if a TT Leggy has made it to 2026 without letting go then it's probably fine.   I don't think a single human has ever put a Link in a Legacy and kept it twin turbo, ha.
