Niall Kelly Posted December 9, 2023 Share Posted December 9, 2023 Hi everyone, Apologies this is a long one. I'm looking for any help possible with an issue I have with my 2013 Audi A6 2.0D. Recently and completely randomly the car has started throwing up multiple warnings on the dash including; parking brake error, headlight malfunction, stop/start fault, indicator malfunction, the list goes on. On 2 occasions now the instrument cluster has completely died whilst driving. It then takes multiple efforts to turn the engine off and then the same again starting up, sometimes it will keep trying to tick over and then stop. When I do turn it off and lock the car, the radio and dashboard are still on. I got a local audi specialist to look at it and they found multiple error codes but nothing decisive, tested the battery and said the battery health is 73% (so fine apparently). I think I have picked up that it happens when it has been raining?. It often disappears the next day. Has anyone had any experience with this before I send it to audi to be charged huge amounts for trial and error diagnostics. Thanks in advance.

Steve Q Posted December 9, 2023 Share Posted December 9, 2023 How old is the battery? A failing battery can throw up all sorts of warnings and electrical gremlins as it fails to provide enough power to all systems. Quote Link to comment Share on other sites More sharing options...

I'll have to double check, I have had the car about 3 years and haven't changed it, but I'd guess considerably older than that Quote Link to comment Share on other sites More sharing options...

This evening the same happened again but now I can't get the car started again, it starts and then immediately dies? Time to take it too the garage I think Quote Link to comment Share on other sites More sharing options...

Niall Kelly Posted December 20, 2023 Author Share Posted December 20, 2023 Had the battery changed on Sunday for this and unfortunately still have the same issues, I have now lost power steering as well. Unless anyone else has any ideas I think I will get it into an auto electrician. Quote Link to comment Share on other sites More sharing options...
Magnet Posted December 20, 2023 Share Posted December 20, 2023 New battery coded to the car? Alternator output checked? Kind regards, Gareth. Quote Link to comment Share on other sites More sharing options...
