I have yet to receive any response to my request for service lodged on 4 August 2010. As promised, I have provided to my dealership here in Alaska. I am very disappointed once again in your lack of attention. I'm now going to the following site to post this complaint so others may be forewarned at the lack of service. Https://www-ODI.NHTSA.dot.gov/IVOQ/complaint.cfm my message from 4 Aug 2010 that went un-addressed: I am very disappointed in the way Audi is handling the injector and misfire on my 08 RS4. I have had several Audi's and you have now put my dealer in a position of not addressing the real issue on the poor running of my Audi. I've taken my car in several times for a check engine light warning. Diagnostics revealed misfiring on several cylinders but rather than address the problem with replacement of the injectors or a thorough cleaning/inspection of the valves, I've been sent away with what amounts to an engine treatment solution. You have not allowed morrison auto group mechanics to properly investigate and cure the problem. You have rather chosen to take progressively futile attempts to placate me and the issue costing me time and money. By not allowing the dealer to take the necessary corrective actions, you now threaten to ruin what was once a good relationship. I demand that the fuel injection and misfire problem with my 2008 Audi be corrected while still under warranty. Further, I recommend that you authorize morrison auto group mechanics to make the necessary diagnosis, and to effect repairs at once. Audi of North America business model for service has soured me on the brand and will weigh heavily in my future plans for purchase of another car. Very disappointed, vocal, and connected with many car/motorcycling enthusiasts via blogs and web sites. I promise you I will follow through if Audi doesn't. I have saved a copy of this message and will provide to my dealer and associates along with any response from Audi North America.
