n55 M2 DCT jumping into neutral

Sparky68 · 12-01-2023, 01:54 PM

Anyone experienced the DCT box selecting neutral on its own? Did it a couple of times on the way to work.

Door open?

During regular driving at speed? When did it occur? I've only had this happen when I'm parking at slow speeds and the car starts to roll backwards a bit

Was entering a roundabout at 40mph, door definitely shut

OK update on the transmission issue. Can't get it to replicate it in comfort but does it without fail in Sport

What I found:

Door may be open, and you not know
Too cold out
DCT wiring harness?
Could need a dealer update

Will look into those although pretty sure the door was shut unless the door sensor is faulty. Thinking about doing a Cs flash and go from there

CS Flash has sorted it out thankfully
