hello everyone, a mercedes class A180 cdi version W176 year 2012 with engine warning light on and star-stop restriction has come into offi ce

doing diagosis gave as error p0226 active with active diagnosis I tried to control the throttle valve on the manifold and it did not respond because it was blocked I replaced it after doing all the resetting and activating the error reset

after two days the customer came back with the warning light still lit re-diagnosis still error P0226 active unplugging and re-plugging the accelerator pedal connector the error was reset I went to buy the pedal in Mercedes and replaced it all OK

after two days again the same problem as error P0226 active....

I ask if any colleagues have experienced such a problem Thank you

Pasquale Velotti

I would like to point out that during the two-year Mercedes warranty period the dealership replaced both the engine control unit and the accelerator pedal.
