Engine torque: Diagnostics

In the event of erroneous engine torque information, the diagnostic trouble code C1928  is set, the ESP/TCS function is disabled and the ESP OFF lamp lights up.

In the event of a fault in the Trionic system's throttle control (limp-home), the CHECK ENGINE lamp will come on and the fault can be found in the ECM.

If the ESP control module is programmed for the wrong engine variant or transmission, diagnostic trouble code C0551  is generated.
