Audi Driver Posted August 22, 2022 Share Posted August 22, 2022 (edited) Out driving suddenly the Audi A3 2.0tdi 2016 red battery light came on whilst driving. Nothing else happened. On way back home the red battery light came on and doing a 3 point turn the steering went heavy. Then TPMS error came disappeared, then yellow battery light then battery went flat, is it battery or alternator problem? Car jump started but gone flat again, showing yellow battery light so far Edited August 22, 2022 by Audi Driver Spelling Quote Link to comment Share on other sites More sharing options...
Magnet Posted August 23, 2022 Share Posted August 23, 2022 Hello Jo, Thanks for joining and posting your plea. You need to get the alternator output checked, together with the battery efficiency ( when it’s been fully charged again). Halfords should be able to test this for you. If it proves to be alternator issues then I would favour getting yours reconditioned via. an auto electrician, since there can be some inconsistent quality ones available, which may be cheap to buy, but not so cheap when you pay for removal again after fitting. Hope some of this helps, Kind regards, Gareth. Quote Link to comment Share on other sites More sharing options...
Audi Driver Posted August 23, 2022 Author Share Posted August 23, 2022 (edited) The battery does not fully charge up to hold charge as it was jump started via jump leads and then went flat after driving and parking. It's currently flat Edited August 23, 2022 by Audi Driver Quote Link to comment Share on other sites More sharing options...
Steve Q Posted August 23, 2022 Share Posted August 23, 2022 I'd be getting the battery checked as first port of call. But you could also get an auto electrican to check the alternator. Quote Link to comment Share on other sites More sharing options...
