Audi Q5 2.0 TDI S line S Tronic quattro Euro 5 (s/s) 5dr No cat 2 keys Monitor CarPlay rear camera The car's engine was overhauled a few months ago. The brake pads and discs were replaced recently, and the belt was just changed. Everything runs perfectly; the only thing is that the check engine light comes on sometimes. I had it diagnosed, and they said it's due to the AdBlue hose, but it doesn't affect the car's performance.( The replacement cost for the hose is 250)
