Jas11n, that sounds exactly like my issue, especially since it has only started in the last month, but was fine over winter....Does anyone know if they're still available from the dealers?

In the short run, replace the 20A yellow topped thermal fuse with a 20 Amp (yellow) spade fuse. If it blows when you move a window or the sunroof, you have a wiring problem that you need to sort. If nothing happens, i.e. the window and sunroof function normally, even after the car heats up, you are done.

Yes, it's a double size relay, 287 in your picture. John

Thanks. Any confirmation of the PN? 441959257D or ??

Well
I also have small little cheaper looking thermal fuses in the are under the driver’s knee on the relay boards that may be the cause of the fault.
Thanks

John: Is it the "287" relay in the photo I posted above? (And thanks to whoever it was that I stole that photo from). ("Right click/Save-as" is my friend )

.... but also as likely is that the contacts on the relay are prone to breaking. If you have a soldering iron, open up the relay and resolder all the contacts where they join the circuit board....John

Does the sunroof run through the same relay and is this a likely cause, or is there something more sinister or common afoot?

The sunroof does run through the same relay, hence they both stop working together.

It could be the thermal fuse as mentioned above but also as likely is that the contacts on the relay are prone to breaking. If you have a soldering iron, open up the relay and resolder all the contacts where they join the circuit board.

There's a post on here where others have had the same problem and it's worked. Also worked for me.

I was thinking this relay is the culprit, rather than the thermal fuse ?? http://www.s2-audi.co.uk/tech_articl...al/sunroof.jpg ...... but I have had a few beers

Probably but the 441959257C in the photo below has been superceded to the 441959257D, under dash relay panel, position 5&6 (see second photo below the first):



Not sure about the number on the 257C but it should be in the position of the "287" shown in this photo (the 324 is the after run pump relay, PN 447965571A):

Perfect to demonstrate which ones I had in mind. The two small ones in the foreground of the photo.

Thanks Dave.

Hopefully all of this helps the original poster.

Thermal fuse photos

It’s a small little thin two spade relay/switch/fuse, in a cheap looking aluminum silver casing with a bit of coloured paint on the top. I think it’s made in Indonesia or somewhere unusual. The relevant photo would be so much more informative.

Not exactly what you wanted but here are some thermal fuse photos anyway:

from the C4 UrS4 Auxiliary Relay Panel III

Robbed from urS4boy’s link in another S2forum thread active now, when you scoll down and see the fuseboard photos, you’ll see the little “fuses” I was referring to at the back of the fuseboard.

HTH.

Thanks Dave.
