DS5 Sunroof Initialization Error

Thanks. Coding modifications were made to several modules, including the BSI, I believe, but I can't confirm changes to the sunroof control module itself. Were you able to resolve the problem yourself, or did you need professional help? Are there diagnostics I can try before going to a technician?

I tried basic resets like disconnecting the battery, but that didn't work. I ended up at a workshop. They ran a diagnostic scan and found corrupted data in the sunroof control module's memory. The tech reinitialized the module, and everything was normal. A specialized Citroen diagnostic tool, like Diagbox, might be needed to reset the sunroof system.

Thanks for sharing. I visited a workshop with diagnostic tools. The issue was corrupted data in the sunroof control module, needing reinitialization. The repair cost 75€ and fixed the problem. Thanks again for your help.

I have a DS5 too. Your description sounds awfully familiar. I had the same symptoms – sunblind jammed, panoramic roof unresponsive. Did the coding changes involve the body control system or sunroof control module? These modules communicate on a CAN bus, so disruption or incorrect coding could cause issues. The BSI controls many car functions.
