V70II does not accept gas – AGR – valve ? Hello, my V 70 II (S) 2.4 CDI Year of construction 12/ 2005 MY2006 Power: 120 KW / 163 PS does not accept gas since today and shows engine maintenance required, after I have run the last 22000km absolutely error-free. More precisely, it starts still (bad), when you give gas it goes out. The ADAC has read out the error codes. Result: 22639 engine control unit – signal faulty 17568 exhaust return valve – sensor faulty The ADAC-Mensch then hit again violently on the AGR and the engine took gas again for a short time. It taps therefore on AGR – valve, on the other hand error number 1 engine control unit came again and did not delete itself. Should I replace the AGR – valve? Is anything to consider? Thank you!
