    Hello all,today i took the time to change my headlamp washer pump so i tought i could share the 'experience'with other and took some pics on how to do.Got the pump from ebay with 17£ and the seller name is 'platinumcarparts' don't know how much will be from the dealer!
    i will try to take you to the steps
    1.jack up the car
    2.take off passanger side wheel
    3.take of plastic wheel arch cover(10mm bolt and 4 plastic rivets)
    4.locate the pump(pics to see) and remove connections
    5.after fitted the new pump there was a slight leaking so if you order from the same seller you will have to take the green seal from the old pump and fitted on the new one(last pics shows you where was the green old pump seal)
    6.ready to spray!!

    if there's something you don't understand just ask..have more pics to upload but uploading space wouldn't allowed me

    pump issue

    hi there
    I think I have the same issue?
    am I correct in thinking that the headlamp washer pump is the white upright pump and the black one next to it is the windscreen washer?
    thanks

    Correct, the bigger pump is the headlamp washer.

    thanks for that craiglxvii. ive just put 12v direct onto the pump after removing it and it don't "pump" so I'm guessing its seized. can they be repaired/dismantled or do I need to buy another?
    thanks

    Just buy another, they're a few quid from eBay. I got a whole wash tank including both pumps for my CL from the breaker network for £20 to give you some ideas.

    Had same problem - replaced pump myself

    Firstly - thanks todea for the details - I wouldn't have attempted it if these details were not available.

    I'd like to add a couple of points I think would be useful.

    Firstly to confirm the fault - headlamp washers were not working and there was no sound when pressing the button. I checked the fuse first (Under the bonnet UK drivers side).

    I got a replacement pump for £10 from a local Merc scrapper - but have seen many new available on ebay for around £12-£15.

    My CLK 55AMG failed the MOT on the headlamp washers not working (and two front tyres...tracking also sorted now!). Working headlamp washers are essential for Xenon lights - although this is the first time the MOT testers picked up on them not working in 4 years!!

    So - booked the retest for 10am and set out to a quiet corner of a local ASDA multi-storey carpark at 8am as it was raining :)

    A few (hopefully helpful) Observations:
    1) The cover under the wheelarch is towards the front of the car. Mine had 3 x 10mm bolts, 1 x 8mm and a plastic rivet that I was able to rotate the cover around and not completely remove. The wheelarch cover that needs removing is just the front part about 25cm x 25cm - not the whole lot.

    2) The tube that is inline with the pump is pushed into a seal at the bottom of the washer reservoir. When you pull the pump out (upwards) the reservoir will empty itself all over you and whichever nice clean carpark you chose. I found it was easier to pull the old pump out and push the new pump in while the old one was still connected, then reattached the outlet hose. so:
    - Remove outlet hose clip
    - Remove old pump from the reservoir
    [Starts leaking liquid here]
    - Move the outlet hose from the old pump to the new one
    - The take your time removing the electrical connection which was extremely stiff on mine and required a certain amount of mole grips and bravery (stupidity?)

    Another note - there were holes in the wheelarch cover where the tyre has at some point pubbed against it. Therefore the pumps and all the cabling were covered in mud and needed cleaning up.

    3) Make sure the outlet hose is fully connected - and test it before you put the wheel back on. The first time I tested it the hose blew off and sprayed the inside of the wheelarch with screen wash.

    4) You can hear the pump very clearly from inside the car with the doors shut. If you can't clearly hear a noise when you press the button - the pump is not working (obviously check the fuse first).

    5) The whole thing from start to finish took me about 45 minutes. About 10 minutes of this was wrestling with the power connector trying not to trash the cabling...and a few minutes of hiding behind the car when carpark security were doing their rounds ;-)

    Thanks again for the post - it probably saved me £80 for an hour of mechanic time.
