Hi,Members This 1 came in with SES Light ON and the customer explain me that sometimes before stopping the car engine start to surge and immediate stop - but she could start it again. I used my scan tool and got these DTC's - P0400 and P1405. I found that the EGR Valve not able to closed the pass well and this was the reason to stall. I replaced it with a new 1 but not OEM and did a test drive - and every thing were O.K. Day after the customer come again with the SES Light ON but without any stalls complaint,I scan it and found again the P1405 - I did the all checks as were descriebed by Opel dealer and it send me to ECM problem... I'd be very happy if somebody will send me any advices - Thanks,Benzi
