Theextra numbers are A,B,C,D,E and F. 0-10 in hex is 1,2,3,4,5,6,7,8,9,A,B,C,D,E,F,10, but Hexs 10 is Decimals 15.

Hex format is a hexadecimal number, used by computers to count in base 16, so there are 16 numbers before "10", instead of our ten.

Those fault codes are decimal. The engine control module will indicate the fault code P10E0 or Valvetronic Overload Protection Control Motor System Shutdown in the case of poor electrical connections or an open or shorted circuit within the valvetronic actuator motor. We thank you in advance.

The engine control module will indicate the fault code P10E0 or Valvetronic Overload Protection Control Motor System Shutdown in the case of poor electrical connections or an open or shorted circuit within the valvetronic actuator motor. Once your BMW engine control unit (ECU) records a fault code, you will likely get a "Service Engine Soon" or "Check Engine" warning light on your dash. Most of BMW diagnosticsoftwareslike DIS, INPA, EDIABAS, IBUS, CANBUS, CARSOFT, give an error code but no or limited explanation.

2. MS41, MS42 and MS43. The next generation Siemens MS ECUs introduced many of the OBD2 features. WebBMW Fault Code: P10E0.

The ABS 3 system added yet more features to the previous systems, such as individual, wheel speed comparison over long terms.
