1 First Name: Farzad Location: Portsmouth Audi Model:: A6 3.0 DTI Audi Year: 2011 Posted February 23 I have A6 3.0 DTI Avante 2011. Last week I noticed for first time a message on my dash board.."Key weak battery". After that the MMI displayed started having mind of its own, coming on and off when it wanted.
If you have vagcom, you can diagnose the problem. If you have sound, the problem can be the screen. If you dont have sound, the problem can be Gateway. If you dont give a code your new battery, it work but it is advisable code so that sistem knows that it has a new battety and what battery. Hello I haven't had a look further into mmi settings but I recently travelled through France Belgium Netherlands and Germany..When I left the ferry in Dunkerque the sound was gone.I thought no problem drive a few miles that you get out of port but unfortunately I did not get any sound in any of tSupport. Help plz, just bought an 06 plate a6, 2.7tdi quatro, the guy I bought it from said he renewed the battery but did not code it in with a diag machine, the mmi now doesn't work if u switch it on it comes up with the audi logo for about 30 secs then flashes a message about a component not being supp
