Has anyone actually found a reliable Audi gearbox service in Dubai?

I'm completely stuck with my 2014 Q7 and its ZF 8 speed that's started slamming into drive with a loud clunk, and the two places I tried so far couldn't even read the transmission codes properly because their scanners were outdated. One guy just said "it's normal for older Audis" which I know is nonsense, and the other quoted me for a full replacement without even dropping the pan to check for metal shavings. I really need a Reliable Audi Gearbox Service Dubai that has the proper diagnostic equipment and won't waste my time or money guessing. I don't mind paying a fair price, but I'm tired of driving across the city to places that claim they're specialists and then clearly have no clue. If anyone has a shop they've personally used for something more serious than just a fluid change, I'd be super grateful for a recommendation before I lose my mind.
