Hi all,

It seems that the only established DIY option for fixing heat cracks on the headlight glass/polycarbonate is replacing the entire headlight assembly as of now, and unfortunately good condition examples of the whole assembly are quite pricey. I think if I recall correctly that the cited reason being that the headlight assemblies are sealed to prolong the life of the bulb. Is this true?

Has anyone seen these aftermarket lenses or shells that seem to have appeared on eBay recently? Last time I searched for headlight replacements I didn't see these. I reached out to the seller to see what the recommended installation process is like, hopefully it's something that is actually DIY possible and also hopefully not just an adhesive layer over the existing lens.

 

this may help.
getting out the angle grinder is scary

 

ANY UPDATES? I am in the same boat...

 

Kind of confusing?
He calls it glass but the description says it's PC (Poly-carbonate)?
He also states it replaces aftermarket lens covers? What about stock head lights?
Just not clear how these are installed either?

As the posted video above shows I have only seen people saw the clear covers off. So do these glue in place after you remove the stock ones?

Agreed. Did a search here, most of the advise is, “It’s expensive” and “It’s covered under warranty mate.”

I'm the third owner of a 2016 S, so it’s not under warranty. I should just roll over for it’s expensive? That’s not like this forum. What are others doing?

 

No real update on my end. The eBay and AliExpress sellers I reached out to all said either “have a professional install them” or “no installation instruction provided” lol

looks like the above video is the recommended way with removing the existing shell with a heat gun and reapplying adhesive and installing the new ones. Looks very involved but might give it a shot eventually.

 

The heat gun method is the old way and I thought that video showed you had to actually saw the head light open?
Jaguar changed the adhesive and on my old S-Type you could bake them and take it all apart but the newer cars this does not seem to work anymore?

I have donor headlight that I just replaced otherwise I would try this. IF anyone wants it to try I would let them go for a reasonable price. One has a shattered lens and one broke tab
Matching one the lens is showing it's age but highly usable. I upgraded to auto leveling versions.
2017 chrome bezel non adaptive all tab's intact on good one, missing one tab on shattered lens.

 

I did these lenses once for a BMW Z4 and it was a hell of a DIY job.
the complete headlight should be warmed up in a oven/stove for the seal to get soft. The proces of dismounting the original lens was a **** Job because there is a lot of force invalved. I ended up to dremel/saw the lens in pieces so I could remove it piece by piece.This was excellent sealent that BMW used 💪.
Once the base and inserts where clean, the new lenses are easy to mount/seal and the headlights looked new again.
