Seemed to have freed themselves up and are operating g as expected.

Thanks guys. 1 can of isopropyl and 1/2 can of STP carb cleaner they’re starting to free up. I’ll carry on over the weekend and see what happens. £20 on spray is better than a new back box

Just seen something on the B7 forum that explains everything.

Now need to soak them in wd40 and hope they start working

Hello all, I’m a new owner, had my RS4 a week now and I love it!!

Cleaning it today I noticed my left exhaust flap open, the right one closed. It was last used in Dynamic. The right one feels really stiff.
What should it be like?

Thanks in advance and sorry if it’s a daft question.
