w219 CLS 320- Distronic and Keyless
u0101 - Limp Mode
Hi guys
i have had my 07 CLS 320 CDI 6 days, now it is in limp mode.
I have read previously using snap on and got code P0715 - Turbine Speed Sensor.
Now the car wont change gear, no gear in dash display.
Got code U0101, no communication with TCM.
Now i believe that it needs the valve body changed as common with this gearbox.
I dont want to get rid of the car, because it has good history and has keyless and distronic, which wasnt reflected in price (Dealer unaware).
If i get the valve body replaced, will this sort it?
