I have a 2000 s3 and it has started to cut out while I am driving or when I am stationary,when it does cut out the engine management light comes on and the EPC light comes on,I have had it plugged in the to the snap on machine but it comes up with nothing....I don't know if this has anything to do with it but the oil light on the trip computer Keeps saying it needs oil but I have checked it and it don't need oil,think that's just a sensor in the sump tho....any ideas why it's cutting out?
