Cls63 upshift issue
hey Guys so my problem seems to be that the tranny is always trying to shift into the highest gear, used my
buddys star to chase it down. It looks like the no codes or faults, under the switches and buttons menu you can see live data of the steering wheel upshift constantly being operated, i unplugged the upshift switch from the steering wheel. Still does the same thing. When you put the car in M it quickly upshift at low rpm. I’ve replaced the steering angle sensor, module inside the steering wheel that controls the buttons. Cleaned the tcu connector under the car.
I need help, it’s seems to be a can issue.

Do you drive the car hard or pretty slow and relaxed? Have you tried a simple ecu reset to see if it wakes up the car as it was brand new from the factory without the learnt driving memory stored
