Nah its under the scuttle panel, its a coke bottle with a hose fitted to it. I dont drive in the rain so i only fitted it for MOT purposes.
i keep thinking these little 'removals' of various underbonnet items like washer bottles, air con etc wouldn't make much of a difference. but i guess their collected weight is quite a lot and does make a difference!
aye but the standard washer bottle is like 5L volume, thats gotta be pretty heavy when even half filled.
