My driver side head light lens is turning a milky yellow. Found the washer fluid container to be filled with snot, sucked out with shop vac. Put some vinigar in then tried to flush. Head light washers working, blew out lines to wipers but the Tee or diaphragm is bad. Can you buy a new diaphragm or must you replace the entire line. Dealer does not show just diaphragm. This is a 2007 xkr. Thanks for all the tips I have followed them all and love driving her.

 

I always thought that for the headlight units, they needed to be replaced as a whole.. but some garages actually dismantle them to get the unit fixed.. I hope you dont have to buy a completely new unit.. as it is expensive..

My NL garage seems to be able to fix them (exco.nl) perhaps they ship too

 

Thank you I will go to that web site and ask for help.

 

Is it the plastic lens that is milky. If so you can refurb them. I used a 3M kit bought from Amazon and it works brilliantly.

You can watch how on YouTube

Just Google 3M headlight refurb to find it.
I used a sealer afterwards which I also bought from Amazon. They now look nearly new.
Just follow the instructions and it is easy.

 

I used the 3M kit with great results too!
This is the kit I used

Is the milky substance on the inside or outside of the headlight? Newer model XKs have experienced moisture in headlights which causes internal staining of the headlight. There is a TSB on this. I also read that older model years had seal issues.

I had a moisture issue in my headlights but had the dealer replace both headlights as it was under warranty. Depending on your situation, there is a link that you may be interested in regarding headlight staining issue

Thank you for the replys. I was not clear on my request. It is actually the small round lens inside of the head light. The outer part has been polished. There must not be a good seal as a spider is now inside.
