Mercedes B Klasse sun blind problem

My 2012 Mercedes B Klasse with a gasoline engine has a sun blind issue with 288402 km on the clock. The window visor seems stuck and doesn't retract or extend. I checked the error memory and there's an error stored related to it. From what I've read, the motor for the sun protection is likely defective. Anyone else experienced this? Getting quotes around 330€ for repair, seems steep.

I also own a Mercedes B Klasse and encountered a similar problem with my car sunshade. The symptoms you describe align with what I experienced. Essentially, the motor responsible for the UV protection's movement failed. It's like a small electric gate refusing to open or close. Did you notice any unusual noises before it stopped working entirely? Has the car interior been exposed to excessive heat recently?

No strange noises before it packed in, and the car interior wasn't exposed to unusual heat as far as I know. So, the motor was definitely the issue in your case? Just trying to be sure before I commit to the repair. Was your car sunshade completely stuck as well?

Yes, in my case the motor was indeed the definitive issue. The window visor became completely immobile, preventing any adjustment. The repair involved replacing the motor, which resolved the problem entirely. Given your error code and the symptoms you describe, it seems highly probable that you are facing the same predicament. I would recommend getting a professional diagnosis to confirm, but be prepared for the motor replacement.

Thanks for confirming. Sounds like I'm in for the motor replacement then. I'll take it to the workshop to get it sorted. Appreciate the help.
