Hey, no problem, always happy to help! So with such a young car and a recent service (only 1000 km ago), the battery sensor could really be the cause. But it could also be due to conspicuous earth connections or perhaps a defective alternator. I remember on my A4 they also checked all the connections and even tested the alternator before replacing the battery sensor. That cost extra, of course, but safety is important to me and I didn't want to miss anything. Hopefully it won't be that expensive for you and you'll get off lightly. Maybe it's just a small thing. I'd be delighted if you could keep us up to date here in the forum. See you then and good luck in the workshop! Your car fan

Hey car fan! Thanks for your advice and tips! I will definitely have all the connections and the alternator tested before I replace the battery sensor. I also hope it's just a minor thing and won't be too expensive. I will definitely let you know what comes out. Thanks again, your help has really helped a lot! See you then and take care, your Audi fan

Moin, I had a similar problem with flickering lights and a low battery when starting. In my case, it was actually due to the battery sensor, which monitors the battery charge level. If this sensor is not working properly, this can lead to the symptoms described. The workshop checked the battery sensor and finally replaced it. They also checked the alternator to make sure it was charging correctly. After replacing the sensor and checking the alternator, everything was fine again. I would recommend that you have the battery sensor and alternator checked at the garage. That should help you. Good luck and I hope your Audi runs smoothly again soon!

Well, that rings a bell for me. I had a similar problem with my 2016 Audi A4 (gasoline). But before I go into detail, let me say that I'm not really a car mechanics professional, but a kind of amateur with some experience - so please don't compare me with the professionals! So, to the story: At my garage, it turned out that the battery sensor microprocessor was defective and the battery was not working correctly as a result. If I remember correctly, it cost me around 315 euros to replace it. But to help you specifically, it would be great if you could provide some more information about your car. Anything important, such as exact model name, mileage, last service, etc. Without that, it's difficult to give precise tips. Greetings, your car fan
