2000 S4 my check engine light turned on awhile ago so i got it scanned and it said random misfiring. so i changed the spark plugs and the light turned off and on again.... i brought it to a shop and they said i need new igition coils but a few days later it turned offthen on again...[:@]he also said my heat shield was rattling but i dont know. i dont want to bring it to the audi dealer ship cause they charging a lot of money and i aint that rich. anyone know a good place to get it checked at cause i need a maintaince check anyways at 120k miles around the BAY AREA (SF) thanks.
