W210 Windscreen washer fluid disappearing!

[Johnniek]

My s210 320 cdi's windscreen washer bottle is emptying itself. Fill it up with screen wash and a couple of days later it is bone dry. A bit of a pain.
Any thing obvious to check?
Cheers JK

Look for drips underneath the reservoir.
There may be drips under the car if it is emptying so fast.
Also check under the headlamp washers

I suspect one of the headlamp washers may be constantly dripping due to a failed valve.

The easiest way to check is to add some coloured dye to the washer bottle, that way you can see where it stains.

its the o ring on the pump

+1 for Pump to reservoir "o" ring.
Check both pumps, (headlight and windscreen).

Could be the O ring as said...but on my car it was the off side lamp washer...I learnt not to use them...as soon as I did it would empty.
