Washer bottle leak?

[mattbarber]

Hi all,

B5.5 Highline Saloon 130 AWX (for the win!) lol
I think my screen wash bottle must have a leak, my warning light and message beep pops up. Usually my screen wash would last ages, but now every month it seems, my beeper comes on - and it takes 2 litres to fill it back up to the neck.

The thing is, I'm no way using 2 litres since I last filled it, maybe half a litre at the very very most.
Maybe it froze and cracked the bottle in winter, but I'm pretty sure it didn't freeze, or maybe an O-ring on the pump / sensor?

Not sure....but...how easy is it to get to the bottle? Inner arch liner out? Hopefully not intercooler off to get to it? I can't see any leaks on the ground, but does have an undertray etc....
