Cruise control error in Mercedes B Class 2021: looking for expert advice and a reliable workshop

Fault stored

|

Cruise control without function

Hello folks! On my Mercedes B Class from 2021 with gasoline engine (mileage 169171 km) the cruise control no longer works properly and there are errors stored. Has anyone had similar problems and had good experiences with their garage? I unfortunately had some difficulties with my mechanic last time. Would really appreciate your opinions and advice, thanks!

Hey, I somehow had the exact same problem with my 2018 Mercedes C Class. It turned out that the engine control unit was faulty. Yes, it was a serious problem, had affected my cruise control the same way and produced error codes just like yours. The guys at my garage had to completely replace the engine control unit to get the problem sorted. You'll probably have to do the same. From experience, it's not uncommon. Hope this helps you!

Hey, cool that you're helping me out! Interesting that you had the same problem. Do you happen to remember what you had to pay to replace the engine control unit? And were there any other problems after that, or was that it for now? Thank you for your help!

Hey, sure, no problem! I paid €1000 for the repair of the engine control unit. Sure, it was a big expense, but after that everything went smoothly again, including the cruise control. So no more problems since the visit to the garage. Hope it's the same for you!

I'm very pleased to hear that! Your contribution really makes things easier for me. When you're talking about €1000, it's a big investment, but certainly not so bad if everything works without any worries afterwards. Thank you very much for the detailed information. Your experience has helped me a lot. Have a nice day!
