						Hi all, owner of a D4 SE 2010 3.0 for 25K kms and it would seem my headlight washers dont work.Correct me if I am wrong, they come on with windscreen squirters and headlights on once every 5 washer squirts?? Anyone know where to start in locating a problem, does it use the same motor as the windscreens? plumbed to ?
Thanks in advance Paul

						Yes I know thats how they are supposed to work, but mine dont.
Ok, is the washer bottle full? There is a sensor in the bottle for low level & if not above this level will only squirt windscreen only & not headlights.

						Yes I checked that thanks.
Have you checked fuses? Located behind lower glovebox.
Bottle has 2 washer pumps, One for front & one for rear.
Both located L/H/F of vehicle, may need to either remove wheel arch liner &/or bumper to gain proper access.
Swap over washer pumps to see if the other works well & that will tell if it is the pump.
Has it had a bumper/bullbar replacement?
Cheers

						SubscriberId be glad if mine didn't work they annoy the hell out of me when the car is freshly washed and want to wash the windscreen sometimes the lights are on and sprays all over the car!! Haha
I'm to be convinced that they actually "wash" anything.

						SubscriberThey will clear a small amount of fresh mud off the headlights to a point but otherwise they just make an annoying mist !
