Hello,

I'm in Australia and have a 97 A4 b5 1.8 Audi. The last couple of summers I have noticed that when the car is idling (clutch out) and air con is on there seems to be a rattling noise almost makes the car sound a bit diesel. The noise goes away when I put the clutch in.
My mechanic asked me to ask the forums as you guys may have more experience with this thang.
Any help is most appreciated
