When I fill my tank the CEL shuts off then comes on eventually. An Indi shop just pulled these codes for me and reset the faults. CEL has been off for 2 days now. If the CEL comes on again with these faults how should I go about isolating the problem?
2 Faults Found:
17547 - Fuel Trim: Bank 2 (Add) : System too Rich P1139 - 35 -00 - -
17545 - Fuel Trim: Bank 1 (Add): System too Rich P1137 - 35-10 - - - Intermittent
Readiness: 0000 0000
Thanks,Adrian

owners a present sooner or later - a CEL.
I think your fault could be related to the fuel tank filler cap or a leak in the venting of the tank. I know it sounds implausable but there is supposed to be a partial vacuum in the tank when running to stop any un-burnt HC's getting into the atmosphere.
I think you may find more by searching on the C5 A6 forum.
