DTCs Set After BM3

N63Austin · 05-26-2023, 10:40 AM

Just curious if anyones had these codes set before, 19 M550i DP BM3 stg 2, yesterday was just cruising in comfort mode, I went to pass someone and kind of got on it hard and a drivetrain malfunction message came on stating reduced power(which i didnt notice the lack of power) but got home and cleared them and they never returned.
Codes were-
21A350 Emergency group error dme coupling
1F2802 DME, software invalid data

Got a similar error today. Running bm3 stage 1 93 tune and got this code along with 120208 followed by 120408 and 120908, all boost pressure controls specifically apart from the DME error. Any return of the code after resetting?

I would contact PTF support with these errors to get their guidance and see if there is a fix needed for these codes.
