I found 200q20v sedan parts, headlight and wiper switch (443 953 503 E) combo, with the trip computer control, but without the rear wiper function. I'm pretty sure I still have the wiper switch from the 200q20v avant I parted 14 years ago, but I'll need to keep digging, and it'll be somewhere I don't expect it, because I looked where I thought it would be and found the sedan parts, but the avant parts were nowhere to be found.
If I don't find mine, hopefully someone parting a coupe sees this and has the part you need.
If you need something before I find my part (which could be a while or may never happen), you could grab this:

I've ordered parts from him in the past, and I've been mostly satisfied. A pair of UrS rear subframe bushings I got once weren't as nice as the used OEM ones I pulled from a parts car, but for the most part, I've been happy with stuff from there, even though everything is super inexpensive.
