Problems with cruise control and error message in Renault Modus 2006: experience and solutions wanted

Hey, I had a similar problem with my Renault Clio 2004, it's more or less the same thing. I'm not a car expert, but I've been able to do a few things myself. When this happened to me, I quickly took it to the garage. They then found out that the control unit was faulty. Unfortunately, there was nothing I could do about it - it had to be completely replaced. Unfortunately, it cost me around 1000 euros. Perhaps it would be helpful to know whether you had any special incidents while driving or noticed anything in particular? Did the problem occur suddenly or did it develop gradually? With a little more information, I might be able to help you in more detail.

Hey, thanks for your quick reply! There aren't really any major fluctuations or particular incidents when driving. The problem has come on gradually, at first only now and then, but now it's permanent. The speedometer is acting up and the cruise control doesn't work. I had already thought of a problem with the control unit, but didn't hope for the shock. Well, what the heck, let's see what the garage has to say. Hopefully it won't cost too much money. I only had my last service at 50629 km, everything was fine then. Thanks again for your help, if you can think of anything else, please let me know!

Hey, no problem! I'm glad I could help you a little further. A few extra thoughts on this: if it has occurred gradually, it could perhaps be due to the sensors or possibly even small cracks in cables or similar. The workshop would have to take a closer look, unfortunately I can only speculate. In any case, it sounds like you're already thinking the right things. Whether it's the control unit or something else - you'll probably have to go to the workshop in any case. But maybe it's just a minor issue and you'll get away with it cheaper than you think. And remember: if in doubt, always ask for a second opinion in case they try to sell you something expensive. Good luck and let us know how it turns out!

Hey, thanks for your advice and tips! I'll keep all that in mind when I go to the garage. I really hope it's nothing major and that I don't have to dig too deep into my pockets. Yes, asking for a second opinion is a good idea. Maybe other garages will have some ideas or solutions that are cheaper. I'll keep you posted and let you know what comes of it. Thanks again for your help and support. You've really helped me. See you then!
