Hello- Just purchased an A8L Quattro, 2007 with 54k miles. Drove for a couple of weeks and got engine warning light. Tested it and it says #6 misfire. Changed the Coil pack and plug. Still idling rough but light hasn't come back on yet. anything I should keep my eye out for?? If light doesn't come back on I'm going to do all the packs and plugs but not till next week. Any help or advise is much appreciated!

I would say that your car needs carbon cleaning.
