Will any fault code produced by the encine ECU automatically trigger a dash warning light for the engine, or could you find a number of fault codes in the ecu without any obvoius warning. I ask as I am getting an intermitent missing from the engine at start up and then occassionally when pushing the engine hard. Wondered whether the ECU might store any clues? (1999 A8 4.2 Q)
