Mine started something similar when the window regulator was on the way out!
I replaced it and it's all good now!
I've got the number of a guy who supplies refurbed regulators on an exchange basis if you want to do it yourself.
Audi quoted me £750 per side and would only do both

Thought I'd say hi[emoji106] and include a couple of pics of the first change I've made to my S5. I wasn't loving the look of the rear number plate so I ordered a smaller version and stuck it on to remove the screws. Also removed the S5 badge while I was there
