    Update on this car.
    Owner came back with EPC light lit.
    Fault code 16786 - Exhaust Gas Recirculation (EGR): Excessive Flow

    Took out the EGR and it was stuck open a bit.

    I took it out and cleaned it, checked function and put it back.

    My guess is that it got dirty from the throttle problems earlier. If it comes back will change it.

    I also but in the 2A fuse on the main lambda, heater circuit. Forgot all about getting two fuses, for both lambdas. But at least there is one.
    Ive been talking to all people I know - and dont know - who works with VAG, here in Sweden, and no one has heard of this problem with lambda heater circuit frying the ECU.
