Well as title states. Started the car today, and thought it was smoke billowing out from under the bonnet!! closer inspection revealed ( once pressure had died down ) that it was the aircon line ( i only re-gassed 3 weeks ago!!!!! ) that has been split by what looks like a poor design!! check your lines guys and put something underneath to support it. The pipe has rubbed on a bare edge of body work and cut through causing instant failure of the line over no doubt a long period of time!! Phoned dealer, its £90 ( with dealer discount as good friend works there. ). Should have been £102!!!!! rip off!! but on back order world wide lol so delivery is 6 weeks!! here is a pic:
if you look its the line which has a flexi pipe in middle of it via a high pressure crimp, its been rubbed by the thin metal body plate bare edge underneath, located on left hand side of engine bay as you look at it.
