Getting that same
cd9437 - DSC, Flexray: communication Fault.
On my 2013 335i f30 after getting a e tune and 2 step colder plugs
Any help on what this would be ?
Im also having issues starting the vehicle in the morning after sitting in the cold all night, first attemp car will not even try to turn over, lights will all go off and im left with “hood open” message on dash
Shut it all off try again and strts right up
Ive attached my codes as well, I believe the mis fires are tune related, and drive train malfunction is from overboosting and diverter valve failing me about 21psi
