Mercedes GT Roadster Sunroof Issue

My 2015 Mercedes GT Roadster with a gasoline engine is showing a 'Sunroof not initialized' error. The sunblind is stuck, and the convertible top won't open or close. The sunblind also refuses to retract or extend. I recently had some coding work done and suspect that might be related. Has anyone run into this before? Any ideas on how to fix it?

I have a GT Roadster as well and experienced a similar issue with the sunroof system after some aftermarket modifications. It sounds like your sunroof control unit might need a reset. See if you can find a procedure for a vehicle sunroof reset. You might need diagnostic software.

Thanks for the quick reply! When you say 'sunroof reset', do you mean a simple disconnect the battery kind of thing, or is there something more involved? And by diagnostic software, are we talking dealer-level tools?

Disconnecting the battery might not be sufficient. The sunroof mechanism likely requires a specific reset procedure through diagnostic software. While dealer-level tools are ideal, some aftermarket options can also perform the necessary functions. I would advise consulting a qualified workshop.

Just wanted to thank you for your help! I took it to a workshop, and they confirmed it was a coding issue affecting the sunroof control. They were able to reset the system, and everything is working perfectly again. Cost me about 75€. Thanks again!
