Psm failure visit workshop error

[Uknown]

My car has been blocked in by a dumpster for 3 weeks… today the dumpster was finally hauled off.
During this time I have kept the car near 80% charge… got in to drive it today and at first stop I have a Psm failure message popping up… have a call into my dealership…but curious if anyone has seen this? It is a MY20 4S. Got the major software update when I bought it in Sept. 22.

Any update on this? I was out troubleshooting a brake noise tonight, and triggered this PSM caution message. I didn't observe issues with the other systems you mentioned, with the exception of the regenerative braking...which after failing caused my braking noise to cease.

Did the errors self-clear?

No. The dealer reset errors and replaced a sensor they felt was causing the initial issues. Haven’t seen another related error since then.

Thanks. I'm starting a thread with more details about our Taycan's issue.
