AC Condensor
 

My X is in the shop tomorrow to have the AC Condenser replaced. The AC stopped working and when it was tested the Condenser was leaking. This is the second Condenser I have had to have replaced. This time I have a warranty so not too bad but is this a common fault? Has anyone else had the same problem and how can I avoid it happening? I don't tailgate or drive off road so i can't understand how the condenser gets punctured.
