Hi all, seems like a good place to start before jumping into a purchase,  I've had a quick flick through forum and I'm sure it's been asked 1000 times so I'm sorry, (BUT) I was hoping to get some advice, I'm looking to buy a q7 and with my budget of 10/15k it seems it's going to be a early quite high mileage model, I'm not to concerned about mileage as long as it's got lots history, I've read about them eating tyres and swirl flap failure, few electrical gremlins but in general is there any signs to look out for that are a walk away warning sign... Also just general q7 common faults. Thanks in advance and any feedback will be very welcome (good or bad) :) 

Hi Lee welcome to AOC and best of luck with the purchase. I believe air suspension can be one of the most common faults on the Q7.
