transferring to A5 from TT

[beatricerossrg]

Hello! After almost ten years of driving a 2012 TT cabriolet, I just purchased a 2022 Audi A5 cabriolet. I really enjoy driving this car, however, whenever I turn, the rear end emits a low-pitched rumbling sound accompanied by a hint of thumping. Before it had the Haldex all-wheel drive system, my TT never had anything like. I was wondering if the dealer should investigate this sound issue or if this is standard on all A5s with the Quattro system. Any advise or help would be much appreciated.

Additionally, I upgraded from a 2013 TT Quattro Coupe to a 2018 A5 Sportback!
So, I'm assuming you've already made sure the trunk isn't hiding anything, like a spare tire that may come free. One of the back wheels may have loose lug bolts. Unfortunately, the most inconspicuous details are often the ones that cause problems. Other than that, is there any urgency given the lack of details? difficult cornering, etc., there is no easy way to diagnose. Have a great time!

Three visits to the dealer were necessary to resolve a similar issue with my 2021 A5.

So glad you were able to resolve that.
Just a couple inquiries. What kind of vehicle is it? A transmission fluid is probably what they mean when they say "clutch fluid" if that isn't the case. Reviewers have suggested changing the transmission fluid every 40,000 miles.
What is your car's mileage?

They are automatics with about 34,000 miles on the odometer.

Wow, that's fascinating. It makes me question whether it was shipped from the factory with any gaps. Other than that, I am at a loss to explain it.
