Ok got a 2003 3.0 quattro and yesterday my mil lamp started to flash at me. It seems the car has a slight studder. It seems to get worse while in park and u gas it. The shake isnt to bad right now while it just sits there but u can tell there is hesistation in the engine. Any insight?

 

I believe that when the MIL light flashes, you are risking damage to the cat conv. That vibration is probably a coil pack that is out. Easy enough to fix and $35-$40 from the dealer if you do it yourself. You will need to get your engine scanned so you can determine which cylinder it is. That should take care of both issues.
