hey guy
i got 03 a4 with 1.8t fwd with a CVT trans. I just swapped the transmission and I got these two codes I know the Tiptronic switch sometimes work and sometimes doesn’t I think the magnet lose or something I have to check on that. But would either on of these code would cause to shift like that?

P1724 I’m not understanding how it’s short to ground if the block is getting good ground contact. How could I find the problem? Bad starter? Before the transmission went out the start solenoid got stuck few time after that been working good.
