All wheel drive system fault

[MattC]

Had my taycan 4s for two days, then it started complaining of an "All wheel drive system fault" and a PSM fault. Was drivable, but didn't seem to have traction control at low speed. Also reported "Parking brake not engaged, car may roll.away" . Briefly also disabled all power for another fault too.

Now been in the garage for a month. Anyone else had a similar issue?

Did you ever find root cause? My MY20 4S is doing this. I have an appointment Monday… but curious what your cars issue ended up being/ what the solution was.
