This is a 6.5L windshield washer reservoir for a W8 Passat - PN 3B7 955 453 D / 3B7955453D - meant for W8s that have the headlamp washer system.  It includes the headlamp washer ( 3B7 955 681 / 3B7955681 ) and windshield washer pumps, the fluid level sensor and the washer reservoir cap. Everything is in good condition and the pumps were tested to function, as well.

Shipping is expensive, as this is a large item - my apologies!
