Anyone managed to repair a headlight washer unit?

Hi guys,

I know a lot of this come up a few times recently following the cold weather but I was wondering if anyone had similar to me and whether they had managed to repair to existing unit. I noticed the washer reservoir had emptied too quickly and refilled to see a flow of water from beneath the front bumper on the drivers side.

A quick look through the empty washer reservoir showed it was not gunk blocking the filter so I inspected through the fog light hatch in the wheel arch. Low and behold leaking washer unit but not from the pipe. Removed the bumper and thoroughly cleaned the unit. Refitted and it worked twice before the leak started again. Anyway, I've cribbed ewazix's picture to highlight were the leak appears to be coming from:

Has anyone taken apart the unit? Its looks pretty well sealed? The unit will twist if you try but doesnt seam to unscrew. However, in operation the unit doesnt appear to twist therefore I was thinking of using a sealant in the small lip around the original seal. Does anyone have a better understanding of how it fits together? Do you think it would be a problem?

Failing that anyone sourced a replacement? Posts on here mentioned £50 - £75. Parts reunited show £36 + VAt and presumably delivery. Contacting soper now to get a quote but would prefer to mend if possible.

Tip to anyone refitting the bumper - make sure you spend some time getting it sat correctly when refitting. Originally I had it to close to the engine to the bonnet would shut properly. Now I've got it too high and the upper of the bumper sits 3 mm too high and looks daft. Whole think will have to come off again!

Cheers guys
 
Ive the same problem. Discovered that the drivers side one is leaking, after removing the wheel arch access pannel. But bit nervous taking the bumper off to see exactly where it's coming from. Was it easy? Ive now disconected the power to the front jets and thought I'd get it repaired when it warms up a bit so it doesn't happen again. Good luck keep us posted.
 
Bumper was relatively straight forward to be honest. It does take quite a pull to get it off from just "above" the reflectors at the top front of the wheel arches. I was a bit worried but wasnt actually a problem once plucked up the courage. Trick is not just to rip it off as you'd probably knacker fog wiring and washer pipes as well as the catches. I had an old duvet laid out to rest the bumper on - something protective on the ground is a must i think.

I obviously need to work on seating it properly as the panel gap is now wrong but I will sort this out when I come to fix or refit the washer unit. As you may also see from my other post, I dont like the rivets now they are back in place but they dont sound like the normal ones. Hopefully Jeeper will clarify that one :wink:

I am thinking of having a look around for something a bit more solid. Surely must be an appropriate fixing somewhere of metal that can be used over and over without a problem.

Will keep you posted as soon as can find time to sort it out.
 
I'm interested in this one as I too have exactly the same issue - driver's side headlight washer doesn’t appear to work (I can see the spray lift from the passenger side when it activates but not the driver's side) and the reservoir empties very quickly. :thumbsdown:
I'm hoping the problem can be fixed under warranty the next time I take it in to the dealership.
 
Add me to the list :thumbsdown:

I've got a missing passenger side spray nozzle and trim, and the drivers side is leaking. I was so bloody smug about my winter tyres that I probably deserved this...

Eyup - I did see another post on here where the poster grabbed the nozzle mid spray and gave it a quick clean and re-alignment - which seemed to work. Worth a try I suppose
 
I got a spare pump body if it will help??

The nozzle's at the top do come out, can't remember how now though :?
 
Hi Gannet. I might take you up on that offer. My drivers side still has the nozzle and trim on the top, so I suspect it is the pump body or the pipework that is leaking. How much do you want for it?
 
I pulled off the bit that fastens to the washer bottle and shoved a small cork in it... pulling the power didn't work for me, it still syphoned out after the first use. I never see the point of those things anyway, they never do anything in terms of cleaning and simply spray washer fluid all over the bonnet of the car. When I replace the car the first thing I will do is pull the fuse to those useless things!

Interesting point there sp3ctre.

Is there a specific fuse in the Z4 to prevent just the headlamp washers from kicking in?

Not sure, but if the system wasn't leaking you could prevent it from firing by pulling the power to the motor, but like I said it didn't help me as it still leaked

I looked at this last night. 3 fuses listed, but I pulled the connector off the pump as it's very easy to get to.

you got PM :thumbsup:
 
I have my Z4 coupe in at a main BMW here in Dublin. I asked them to look at my headlight washers as they both stopped working at the same time (which indicates to me more of a fuse / power issue versus a faulty pump (as both couldn’t fail at the same time?). They don’t even pop up, the units just sit motionless. There are no leaks to my knowledge either.

Anyway, the dealer tells me the washers are 'broken' and asked me if I wanted to replace them. Cost? 294 Euro!!!!! :rofl: :rofl: :rofl:


As Sp3tre says, a pointless thing that does nothing but spray washer fluid onto your bonnet and sweet Jesus, there is no way I am going to spend €294 euro on them! :rofl: :rofl:

Anyway, did anyone have both washers fail at the same time like myself? If there is an easy fix, I will do it, otherwise I will just leave as is. :)
 
I'm still waiting for my next due service, at which point it'll be booked it in for some additional warranty work - which I hope will cover it.
