I've got a 2016 Q7 that's been absolutely brilliant for the family until recently when the air suspension started acting up – the car sits unevenly in the mornings, sometimes drops all the way down on the rear axle overnight, and I've had that dreaded "air suspension fault" warning pop up on the dash a few times now. I've been quoted absolutely insane prices from the dealer to replace the compressor and a couple of air struts, and honestly it's making me wonder if I should just cut my losses and trade the car in rather than sinking thousands of dirhams into a repair that might not even solve all the issues. The thing is, I actually really like the car and it's been reliable otherwise, so I'm torn between fixing it properly or just getting rid of it and moving on to something else. I'm trying to find a specialist who can actually diagnose which specific component is failing rather than just suggesting I replace everything at once, because I've read that sometimes it's just a leaking valve block or a cracked air line that can be fixed for a fraction of the cost. I've been searching for an Audi maintenance specialist in Khalifa City since that's relatively close to where I live, but I'm not sure if these independent shops are actually capable of dealing with the complex air suspension systems or if they'll just be guessing like everyone else. Has anyone had a similar issue with their Audi air suspension and found a cost-effective fix, or is it really as expensive and hopeless as the dealer makes it out to be? Really need some honest advice before I make a decision that I might regret.
