Hi

I have a 2005 Volvo S40 that's recently been fitted with a brand new windscreen washer pump and reservoir tank. However, the water from this tank keeps on disappearing. I haven't used the wipers in quite some time especially to see if the water would still disappear, and it did. About half of the water in the tank was missing even though I havent used water from this tank at all. I had it checked at my local volvo dealer and they could not find anything wrong. Has anyone else had a similar problem? Could it be a leak? Could this water perhaps be used up by something else?
