What is your question?
Faced with the same problem with misfire. Fault codes: P0300, P0301, P0302, P0304, P0305, P0306. These codes are for cylinder misfire. At odd times 7 at low RPM (below 3000), the engine struggles to stay at stable RPM - the tach shows the RPM going up and down. When driving there are no issues. Told the dealer about this some time ago; they blew me off as no problem found (perhaps there was no fault code). Ran Chevron Injector cleaner - no effect. Now contemplating what to do next. Help!
How long has your 2007 Audi Q7 had this problem?

Hello, I'm not Tom - but -- from what I know about the direct injected engines in these vehicles with misfire codes -- you can have injector issues, or you can have exceptional build up on your valves. In some cases the cylinder heads must be removed and repaired. This is all a serious guess but comes with the experience of having dealt with Audi and VW engines of similar fates. Contemplating what to do? You simply need an experienced technician to get involved and help you diagnose and repair your vehicle. And, prepare to spend some money, to be sure.
