I had an issue recently with the coil packs which was covered by a recall.

So I took the car to the Audi dealership and had it done. They even paid for the towing. nice!

Now, while there I also had them fix a leak in the window washer tank ( 170$ ouch ) and they also claimed a fog light burst while they were working on the leak ( 50$! ). 250$ total and I figured the car was good to go.

I managed to stay with my dashboard error-free 1 day only since it now shows that my rear light is not functioning properly. I looked at it and it's definitely on and working. Furthermore, my drivers window won't come down anymore.

Is this just a gigantic coincidence and if so, can I fix these issues easily without getting raped again by the dealer ?

thx
