Hi My name is Sam. My first Audi after years of BMW ownership, I have been converted for life! I have a silver A8 D3 4.0 TDI. I have been having major problems with my MMI system. After spending months trawling the net to find out how the MMI system works. None of the Audi "specialists" I visited would help or did not give me the confidence that they knew what to do apart from replacing expensive parts till they got the system working, I think I knew more than what some of them did! I felt I had no option but to go to a main dealer to get the car scanned. After realising they wanted £96 just to diagnose the car. I decided to invest in a Genuine Ross Tech HEX CAN USB Cable (unbelievable piece of kit) I have now got to the stage where the MMI works fine with the help of a Fibre Optic loop to bypass the amp. The amp does work sometimes. I have checked the connections but I guess something is not right somewhere. At about 1K for a new amp its not going to be a cheap fix. I guess I should have asked for help via a forum but never having been a member of one I went alone equipped with the information that I had discovered online. The car is pretty much as standard as it came from the factory. Once I have the MMI up and running properly I would like to add an iPod connection, wheels could do with a refurb. Possibly some DRL's would be nice too. Looking forward to learn more and help where I can too.
