This is a common fault mate and hence the pipes are like rocking horse poo, This happened tom my MK2 paj and i found that mitsi want about £115 for the pipe :shock: i tried for ages to get a second hand bipe bit in the end i used some of that plastic metal stuff, if you build it up in 2 of 3 layers and cut a slightly larger pice of thube length ways and sandwich it over the offending pipe it will hold.
I know its a bit of a bodge but it meens the aircon stays working .
