Hi my name is***** will be glad to help. That fault is for EGR out of calibration. Try havingthe valve recalibrated with the Volvo diagnostic software and if unsuccessful inspect the harness and replace the EGR valve. Let me know
Hi Mike, You have either a faulty EGR valve/ or out of calibration, harness issue, or ECM software issue. This is related to the EGR valve circuit
Check to see if one of the valves is stuck open. Click on the second link for more info. It shows an install of a delete kit which may not be legal in some states but there is a lot of good information of removing and inspecting your components.
I am not sure I understand what you are saying? You mean the engine stalls? it is possible it would. Fuel system issues and electrical issues could cause stalling as well. Does it sputter and stall like fuel starvation or instantly like you turned off the switch?
The EGR is erratic and not calibrated. Try having the dealer calibrate it with the software... If it will not calibrate it will need to be replaced.
Unfortunately if the EGR is that erratic your EGR valve is faulty. There is two on this engine. Are they both doing this or just one?
The EGR is opening and closing and moving erratically.... It should not be.... It should move steadily and smooth.... Some delete them with a kit if legal in your area but if not you will need to replace the EGR valves.
Thanks for the update. There should be no leaks and also could be part of your problem. Let me know
