Hi friends, I need to know if the ecu reference corresponds to a vehicle with automatic transmission or manual.the vehicle is a manual transmission C4, and presents the fault code (U0103 data bus gearbox module - no communication). I reprogram the ecu with the original software and still the same.
also provides fault with the alternator driven and the speed controller

Tnx
