Cruise control error in the 2017 Audi A3: looking for solutions and experiences

Hey, I had a similar problem with my 2015 Audi A4. I also had a faulty control unit, specifically it was interfering with the cruise control. When I took it to the garage, they had to diagnose it and then replace it completely. It was quite a serious matter because the control unit controls so many important functions in the car. I hope this helps you a bit. It's definitely not a small problem and you should get it fixed as soon as possible. All the best with it!

Hey, thanks for your reply! It really seems to be something bigger with the control unit... Do you remember how much it cost to replace it? Has anything similar occurred since then or is everything running smoothly now? Fingers crossed...

Hey, no problem! Yes, the control unit really was quite a chunk. The replacement cost me a whopping €1000. Not exactly a bargain, but well... there was no other option at the time. From then on, everything was fine. The cruise control has worked perfectly again since then, and I haven't had any more problems since the workshop visit. So, hang in there! Sometimes you have to dig a little deeper into your pockets, but it pays off in the end. Good luck!

Yes, really hefty, 1000 € for the replacement! But I'm relieved to hear that everything went smoothly afterwards. I'll probably have to go through the same procedure... Well, what the heck... Better than not having a car at all, right? Really, thanks for your help and the encouraging words, that was really useful. I'm keeping my fingers crossed and hoping for the best! Cheers to the end of the car problems and to problem-free journeys!
