NFIN02 Posted May 24 Share Posted May 24 My a6 occasionally goes into limp mode with flashing coil light. When car is stopped and left a few minutes it appears to reset and go back to normal. I have scanned and found 2 faults - p200200 and p23700. Advice appreciated please Quote Link to comment Share on other sites More sharing options...
Steve Q Posted May 25 Share Posted May 25 Any black smoke? If so could be a blocked dpf. Is there any lag or whine from the turbo? Quote Link to comment Share on other sites More sharing options...

Advice appreciated please Hi P2002 is the low pressure EGR cooler have a look on the site archives this is well documented the cooler gets blocked with adblue crystals and fails its a horror to replace its not the parts so much as the labour charges, the other one is the MAP sensor which is cheap and easy to change.
