I need to know what the following code is telling me on my 20112 Q5 Turbo. P168200 (1/2)

MP4.2+6.0

This is last generation A8 board. Use Gen 1 Q5 board, but better: just Google it and research for yourself.

I have attempted google; it does not yield any explanation it is what brought me to the AudiWorld Forum which apparently will not get an explanation either.

Well, you might again want to try Gen 1 Q5 board. D3 A8 is not close for most parts or a lot of diagnostics. I own a Q5... That board also several x the traffic of this one. Contemporaneous cousins to it are A4 and A5. D3 A8 is closer to the C6 A6 by contrast.

May want get a different code reader too. P codes are standardized, and I don't think there are even actual six digit (numerals part after the P) codes. Typical codes after the P are 4 digits, with first one sometimes a zero. A good code reader or certainly a more Audi specific tool for job like VCDS or some of the apps should give you a decent text description. I doubt 99% of owners have P codes memorized, so need ultimately to look it up or search (with correct) code on Google.
