So this morning I change the battery in the A8, recoded Battery Module to a Varta with the same CCA (cant buy any actual Euro brands here..) and that was just swell, the power trunk started to work again as does the auto door proximity unlock.
However, decided to resume listening to the CD I had been listening to on the way to the shop and was surprised to find the CD Changer menu there but empty/blank of contents. No error, just blank.

Tried resetting the MMI, same thing. Ejected and inserted a CD, no change. WTH!? Any ideas?

MP4.2+6.0

Give it a few starts to see if it settles down. After that, a VCDS scan to diagnose better.

I'm assuming you don't have AMI--that uses the CD button and then distinguishes between the AMI electronic drive/head and the CD drive. But then it either plays or you get a device not connected message.

Yeah no AMI but got it working again. Think the problem was very centric to this car (Jap import). Basically the Audi supplied MiniDisc player was the issue. I never noticed it also disappeared.. possible when I put in the Euro (France) MMI controller with very old firmware on it. I never upgraded as when I tried this on the Jap MMI it bricked it (and I couldnt see any point now I had all English operation).

When I took out the battery I guess the car rescanned the mediaplayers connected and cant understand what the Minidisc player is. Could be MD is only supported on the Japanese firmwares or was introduced later in Europe. With the MD player disconnected but with an optical bypass in place the CD changer fires right up. So I guess I wont have MD functionality anymore! I might eBay it, its a 3 MD Changer, Audi PN but made by Kenwood.

No problem with updating the MMI now you've got a euro head unit in there. I was a tad nervous after semi-bricking the Japanese MMI, after which I could only re-flash it to a very old Euro version (1110 I think) due to the original head unit being a HW version 41. That version was so old it didn't recognise MP3 CDs or AMI and wasn't happy, much like your symptoms. When I got the replacement interfacebox I stuck the SW update cd's in and it worked a treat, even with several Japanese components still attached. The only problem was that I tried to update the Japanese K-Box software and it didn't take. Hence buying a replacement. I've got the update cd set if you need to borrow them.

I'm tempted to stick a web-page up with a comprehensive set of info about what can and can't be done with Japanese/NZ imports. The info on the web is scattered far and wide and there are plenty of folk in Auckland who seem to be charging the earth for pressing three buttons. Be nice to inform people before they make that choice.
