Q8 Electric Sunvisor Malfunction: Motor May Need Replacing

Had the same issue with my 2017 Audi Q7 3.0 TFSI. The sunshade repair involved replacing both the motor unit and the guide rails of the sun blind mechanism. The main symptoms matched exactly, sun visor getting stuck mid-way and throwing error codes. The root cause was debris buildup in the rails combined with a worn-out motor. This is actually a known issue with the car sunshade systems in several Audi models from that generation. The repair required removing the entire headliner to access the sunroof assembly. The car sunshade motor needed complete replacement along with the guide mechanism. While labor-intensive, this was not a critical mechanical issue and did not affect vehicle safety or performance. Worth noting, the repair shop found the motor failure was accelerated by a partially blocked drain channel, causing moisture buildup in the mechanism. Regular cleaning of the sunroof drains could help prevent similar issues with the sun blind system. The fix has held up perfectly for 2 years now with no reoccurrence of the sticking or error codes.

Thanks for sharing your experience. This matches what happened to my Q8 too, stuck sunshade and error codes. The car interior work was quite extensive from what I understand, but having a working window visor system again made it worthwhile. Did you remember the total cost for your sun protection system repair? Also curious if youve had any other sunshade-related problems since the fix? My car blind issue happened about 8 months ago and its been working fine, but Im keeping an eye on those drain channels you mentioned.

Glad to follow up on this. My sun blind repair was completed and has been working flawlessly since fixing the defective motor. The total repair cost came to 330 Euro, which included the new motor unit and labor for the car interior disassembly. The repair shop made sure to clean all drain channels while they had the headliner removed, which seems to have prevented any recurring sun protection system issues. Zero problems in the past 2 years, the sunshade moves smoothly and quietly now. One interior accessory maintenance tip that helped: regularly cleaning around the sunroof tracks with compressed air keeps debris from building up. This simple step helps protect the new motor from premature wear. The initial cost might seem steep, but having a properly working sun blind system is worth it, especially during summer months. Much better than dealing with a stuck or malfunctioning sunshade.

Thanks everyone for the helpful input. Just wanted to share how my repair went since others might face similar issues. Took it to an Audi specialist last week who actually found more debris in the channels than expected. The car sunshade motor was completely shot and needed replacement. Total bill came to 420 Euro including parts and labor. The UV protection system is working perfectly now, smooth operation with no more sticking or error codes. They also cleaned out all the drain channels while they had the car interior opened up. Whole repair took about 4 hours. The sunshade repair was definitely worth it, even though accessing everything through the headliner was apparently quite tricky. Really glad I got this fixed before summer hits. The car blind system is actually an important safety feature when driving in bright conditions. Would definitely recommend getting it properly fixed rather than trying quick fixes. The debris buildup issue makes total sense now that I understand how the mechanism works.
