Unevenness and warning display: Experience reports on the suspension damper adjustment for Merc X Class Diesel 2020

Hi mate, I had a similar experience with my 2017 Merc S-Class diesel. The control unit actually turned out to be faulty. The warning indicator in the speedometer was illuminated and the driving behavior was a bit strange, just as you describe. The car that jumps and twitches... I know it all too well! The correction was definitely no small job. The problem was actually the control unit, especially the suspension damper adjustment was acting up. In my case, the entire control unit had to be replaced. It took a long time and my car was in the workshop for some time. You should definitely go to a reputable workshop that is familiar with Merc. Let us know how it goes! All the best!

Hi, thanks for your quick reply and the information! The same horror happened to me... Replacing the control unit sounds like a really expensive repair. Do you happen to remember how much you had to fork out at the time? And have you had any other problems since the repair? Thanks again!

Hello, yes, replacing the control unit probably cost quite a lot. I think it was around €1000. But since then, the fault in the suspension damper adjustment has fortunately been rectified. It's usually the case that you don't have any more problems afterwards. At least that was the case with my car. Just give it a try and let us know how it goes! All the best!

Hello, thank you very much for the helpful advice! Even though €1,000 is a tidy sum, I'm prepared to invest it to finally be able to drive again without stress. I plan to visit the mechanic next week and go ahead with the replacement. Hopefully I won't have any more problems after that, just like you. I'll keep you up to date! Thanks again!
