Hello municipality I greet first of all those who are interested in this topic and thank in advance quite warmly to those who provide me with their competent contributions help. My problem: I start my thick the control lights go out as usual, the orange indicator light (motor block) lights up again. Now I give gas and drive off the engine starts to stutter immediately with some forced gas giving. So as soon as some power is demanded he stutters so, a ls the ESP system would slow down the car. As soon as I take some gas away, the stutter stops. I can only speed up the car without stuttering if I tread through the accelerator pedal very gently. But as soon as I step through again the stutter begins again. After a few kilometers drive a control light red (blitz) goes on. I called the ADAC which has read out the following errors: P0403 Exhaust gas return valve P0046 Charge pressure regulation I ask for tips, experiences and your help e when troubleshooting. Vehicle data: EZ: 04.2006 / Km 82.000 / V6CRD / Thank you MfG Yellow phase brake
