Problem with starting and lighting in the Audi A8 (2015, gasoline)

Hello, I have a problem with my Audi A8 (built in 2015, petrol engine). When starting, the battery weakens and the lights sometimes flicker. It seems to me as if there is an overvoltage in the vehicle. Does anyone have experience with such a problem and could give me some troubleshooting tips? I would like to know how such cases were solved in the workshop. Thank you in advance.

An Audi A8 (2015, gasoline) is experiencing issues with a weakening battery and flickering lights when starting, suggesting a potential overvoltage problem. A similar issue in an Audi A6 was linked to a faulty alternator causing surges. It is recommended to have the alternator checked at a garage to diagnose and resolve the issue.

Hi, I had a similar problem with my Audi A6 (2013 model year). I have low experience with car repairs, but I would say your problem could be related to the alternator. On my car, the alternator was faulty and causing surges. The repair at the garage cost 960 euros. But without more vehicle information, such as whether you already have fault codes in the on-board computer, I can only guess. Hopefully this will help a little. Best regards.

Hi, thanks for the tip! I did indeed not have any error codes on the on-board computer. Incidentally, my mileage is 59183 km and there were no complaints about the alternator at the last inspection. I think I'll have it checked at the garage anyway, just to be on the safe side. Maybe it really is that. Expensive fun. Greetings back!

Moin Moin, no problem, always happy to help! Yes, it sounds sensible to play it safe and have the alternator checked. And yes, car repairs can be really expensive. I wish mine had been cheaper. I'll keep my fingers crossed that it's something simpler. Keep us up to date! Have a safe journey!
