Had my Q7 over to repair a fault trough warranty first, they ran a diagnosis, "repaired" the fault, i paid then £634 only for me to collect the car and the issue the remain exactly the same. Contacted them again, said the issued was still there and was told to take the car back to them to be checked out. They ran a second diagnosis, said there was another issue related to the first one that was giving a fault reading. They managed to put another claim trough the warranty and were charging me £1823 pounds for a part that i got for £560. The same part, original, with warranty a third of what they were charging me. In the end i had to pay £605 on top of the £634 because i needed the car fixed. If they had done their job properly in the first place i would never had to spend so much money. Never taking my car to this garage again, ever!!!
