Hi all, just back from another test of the 718. Heavy rain over night resulted in a very annoying dripping noise at the rear of the van, just where my head is in bed! Got up at 5.30 as the water torture got too much and went to find the offending drip. It's coming from inside the offside rear corner panel. Can't see anything but it's definately dripping inside the corner cover. Anyone else had this problem? Thanks all
