Malfunctions in Audi A6: Electrical faults and Flex-Ray bus errors

Moin, I understand what you're going through. I had similar symptoms with my previous Audi A4 (2015, around 30,000 km on the clock). Navi was spinning, the dashboard lit up like a disco and there were general electrical problems. The check at the service center confirmed a fault in the Flex-Ray bus. Fortunately, replacing the affected part fixed it. It was a serious issue, but not a disaster - once the fault was fixed, everything was fine again. So, don't worry, just go to the nearest Audi garage and get it checked. Let us know how it went. Good luck!

Hi, thanks for your reply. It's really reassuring to hear that you had a similar situation and that it didn't break your leg after all. Do you remember how much the repair cost you? Was there anything else afterwards or did it stay that way? I'm really grateful for any information!

No problem, help where you can, right? I can tell you that the repair cost me €155 at the time. It was damage to the cable connection or plug connection that had to be repaired. Since I had the fault on the Flex-Ray bus repaired in the workshop, everything has been great again. So don't worry, everything was fine for me afterwards. I hope this helps you and you'll soon have peace and quiet in the box again! Good luck with it!

It's good to know that it won't be extremely expensive and you can hope that everything will run smoothly again after the repair. I'll go straight to the workshop and keep you up to date. It's really cool that you took the time to reply. Thanks again, that helped a lot!
