2007 A4 Avant 3.2L Quattro, check engine light still on after recent service
 

Hi all,

New to this forum. I'm an original owner of an Audi and seem to always had spark plug misfires/issues. Mileage is at over 117, 000 miles and recently had it serviced due to a very rough and lingering cold start, malfunction indicator light, electronic stabilization light and tire pressure light, all on. Service was done (replaced some spark plugs, oil change...) but malfunction indicator light is still on. Starting to wonder if the Audi mechanics are dragging us along... Would like to know if there is another root cause, is this common Audi behavior or if we have a lemon? I'd hate to have to get rid of my car but this is ridiculous...expensive too. I appreciate any comments and suggestions. Thanks
