Audi A1 airbag lights up in the speedometer after the car has been parked overnight

Hey, thanks for your reply! Do you remember how much you paid for the repair? Have there been any other problems with your Audi since then or did everything run smoothly afterwards? LG

Hey, no problem, happy to help! Fortunately, it wasn't that expensive for me. The fault "airbag system components defective" was fixed by my mechanic and it actually cost me nothing - €0. Since the repair, everything has been running smoothly again and I've had no further problems with the airbag system! I hope this helps you! LG

Hey, that sounds great that it didn't cost you anything! I've now taken my Audi to the mechanic after following your tips. The first step was to diagnose the fault, and sure enough, it turned out that the control unit and some cable connections were faulty. After a few phone calls and a short wait, they replaced the faulty parts. It was a bit more expensive than yours-about €200 in total. But the good news is that everything has been running smoothly again since the repair. The airbag warning light is off and I now feel much safer when driving. It was definitely a nerve-wracking experience, but I'm really relieved that everything worked out so well. Thanks again for your help and info! LG

Hi, I'm having a problem with the rear belt tensioner Nieters on my 2011 Audi ttrs. What should I replace and where can I buy this part? Thanks in advance.

(Translated from French)

The rear belt tensioner is a crucial part of your vehicle's safety system. If it's malfunctioning, it's best to replace it as soon as possible. You can usually find this part at an authorized Audi dealership or a reputable auto parts store. However, I would recommend having a professional mechanic inspect the issue first to confirm that the tensioner is indeed the problem. After the replacement, please update us on the progress. Do you have any other questions?
