Peugeot 108 sun blind failure

That sounds problematic. I've not seen this reported frequently, but sun blinds in general can be delicate. Is the motor making any noise when you try to operate it, or is there complete silence? Is the sunblind jammed?

There is complete silence when trying to use the sunblind. It isn't jammed. What should I check next?

In that case, and given the error code, the motor itself is likely the issue. Further diagnosis might be difficult without specialist tools. Considering the age and mileage, it might be best to consult a workshop for a professional inspection and repair.

Understood. I took it to a workshop and the repair cost was 330€. I presume this is a fair price. Thanks for the help.
