Mercedes Benz B class 2014 2.0cdi d3
The fault code P211907 (A mechanical fault exists in the throttle valve) is appearing and we are not able to program it,the throttle valve is phisicaly clean and is functional. Also the trouble code DTC P063878 appears when the engine is on. 'Chip tuning was done on the car' said the owner. Could that be the reason for the fault code?
