    Hello,I'm not used to communicating in English. I have a problem with dis car. The errorcode indicates a problem with the throttle valve. What are my problem now? This valve are very dirty insite. What could be the cause of this? Except the errorcode P012100, no other codes are generated. Then I assume that the EGR valve still close / works sufficiently. Perhaps I should look the funcion / work of the injectors.
    With which data can I check the state of operation from the injectors without dismantling of the engine? And what are the acceptable data for this?

    Hi,the p0121 vw code means check throttle/pedal position sensor/switch A
    circuit,check the connector and wiring,clean if possible the inside of the throttle valve.
    Don't worry about the egr valve, check the tpS,wiring,connector ,check for poor
    electrical connection, even check or let check the ecm.
