Picked up a used A7 and now it's creaking over every speed hump in JLT, did I mess up-Forum-Culture Informatique

So I finally pulled the trigger on a 2017 A7 that I’ve been watching on Dubizzle for weeks and the test drive felt smooth and the Carfax was clean and I was so excited to finally have something nicer than my old Accord that I probably overlooked some of the little signs like a slight groaning sound when turning the wheel at parking lot speeds and a bit of a floaty feeling on the highway exit ramps that I convinced myself was just the car’s character because German engineering and all that right well fast forward two weeks and now it’s developed this lovely creaking orchestra every time I go over the speed humps in my neighborhood and the front end feels like it’s not quite planted when I’m changing lanes and I’m starting to get that sinking feeling that the air suspension or at least the control arms are on their way out and I just handed over a decent chunk of change for a car that’s about to need a four figure suspension overhaul. I’ve been calling around trying to find a shop that doesn’t just hear « Audi » and add an extra zero to the estimate and a buddy from the office said he took his Q5 to a place that specializes in Audi suspension repair and maintenance Dubai and they were actually honest about what needed to be done immediately versus what could wait a few months and didn’t try to upsell him on a bunch of stuff he didn’t need which is basically all I want at this point because I’m already mentally preparing for the worst but hoping it’s just some worn bushings and not a whole air strut replacement saga. Anyone else bought a used Audi with air suspension and lived to tell the tale or should I start looking at coilover conversion kits and just accept my fate as a guy who bought a fancy German car and paid the price for not getting a proper pre purchase inspection.
