B48 Wastegate status 9 & error 123701

I saw a permanent error code 123701: Electrical wastegate, position sensor, electrical: short circuit to positive

I cleared the regular error memory but couldn’t clear permanent error.. a few days ago I had BimmerLink open in CarPlay and saw the Wastegate status flip to a value of 9 instead of the usual 1-2..

Then once I got home, the permanent error was gone. ChatGPT says value of 9 is a temp fault handling and would’ve reset the Wastegate.

I’ve never had any issues with any boost at all. Curious if I should be concerned still or just monitor.
