HI folks - Just had a look at the washer bottle today and found that one of the hoses that comes off one of the washer motors (the one behind the washer bottle as you look at it) had simply come off and thats why the flippin thing was emptying the entire contents on the floor......Think this happened when the bottle froze and the ice expanded and luckily for me the pipe just came off instead of cracking the bottle...
Might be worth a look for anyone else thats havin this problem before you buy another bottle just to check that the plumbing pipes are connected first...might save a few quid..
I still had to take the bumper off and headlight out to get at it though... Pain in the aris...
