Passenger seat buttons stopped working

[hughmungis]

For no apparent reason I cant move the passenger seat in any direction using the buttons,the only thing i have done recently is have the car valeted but everything else seems ok. Any help please

Does the seat have a fuse or relay anywhere that is reachable or could it be something more serious.

Falling out of love with this thing now, keyless unlock/lock has stopped working recently (prior to valet)and the suspension green/orange lights come on when they feel like it.

I think there are about 3 fuse boxes on most audis now. Finding them is easy, finding the right fuse will be harder. Have you got a manual?

Yes but they dont mention a fuse, i am hoping the control module isn't damaged but can seem to find that either ?

Done a Carly scan and this shows up :-

Anyone know how to replace this as it looks like its toast ?

Think it would be best if you could find someone to scan it with VCDS. There is probably component protection on this module so buying one and getting it wrong can be expensive. I think only dealers can remove CP.
