2019 Q5 AWD clutch replacement

Hi,

If this isn’t the right place to post I’m sorry, just needing some advice. Feel free to point me in the right direction if necessary!

Has anyone had this issue below/could anyone (seriously) give me an estimated cost for this issue if they’ve had this replacement?

My car has been stuttering/vibrating when I turn for a while, I brought it into a European auto shop in Austin and was told they suspect it is an AWD clutch problem based off a TSB they found which affects all Quattro Ultra vehicles. He stated there’s a huge diagnostic tree and suggested I take it to Audi… my car is out of warranty, I can get it diagnosed but imagine the cost would be double and I can’t get an appointment til late September.

Obviously going to get a second opinion from a trustworthy shop I’ve used in Houston area, and will take it to Audi if he can’t help.

Thanks y’all!
