Thanks Omar, and sorry to hear of your issue.
The Audi dealer’s conclusion that everything is fine, is obviously incorrect, unless every 2022 A3 on the road gives the same noise, and always did from the point when they were new.
I guess you can confirm that this noise hasn’t always been present with this car -? If not, the car is trying to tell you something.
Recommendation:- Try another dealer, and request a road test with a mechanic before leaving the car with them.
Perhaps you could let us know how you get on Omar.
Kind regards,
Gareth.
