I have owned X-Types (3) over decades. I love them for all sorts of reasons, but there is one reason for which I am certain that the Valeo and Jaguar engineers deserve a special place in Hell - which circle, I cannot say (see Dante...). Replacing the headlamp bulbs is simply the worst and most labour-intensive job I have ever found on these or any other Jaguars - even though I have done this procedure a number of times. My hands bear the permanent scars as proof.
Today I attempted remove the cover from the right side (LHD) unit to replace a blown bulb. The interference of the ABS unit, the headlamp washer hoses, and various electrical harnesses, not to mention the virtually inaccessible and unseeable clip for the cover....well, all of these caused me to give up for the moment.
I might try again later...or I might not. The rub is that as this is a Canadian-market car the headlamps (and all other exterior lamps) are illuminated all the time - which means that headlamp bulb replacement is a pretty regular thing. This particular car (2002 manual shift 2.5) has served us faithfully and reliably for 18 years and it still runs as new...but the headlamps....ugh.

 

4.5 hours today at the right hand headlamp....why? Well, once I got the bulb out I found that it was fused to the wire connector. Not unusual. In fact it also happened on my Sportwagon. Jaguar has a neat kit to repair this issue (actually a Ford repair kit). It consists of a new ground wire and a new power wire with connectors, and heat shrink tubing. The kit replaces the combined ground/power connector used originally. Enough material for two headlamps.
As I did only one headlamp on the Sportwagon, I had one set of wires/connectors left to use on the sedan this morning. Easy, eh? Not so fast. The miserable bit of access means that it is a $%#+ to strip the original wires, crimp them to the new wires with no room to use a crimping tool - after an hour of contortions and bleeding wounds I resorted to vise-grips, then fit the bulb and the metal clips (a job in itself), then tested (YES! it lives!), then try to fit the cover back on without being able to reach the clip in the deep recesses of the fender...finally having searched out a strong enough flash light (torch) and having made a grasping hook from a coat hanger, I was almost finished...oh, did I say that the headlamp adjustment mechanism broke?....

So, any Valeo engineer I happen to come across will be in mortal danger.

 

I hear ya. I tried to do the H IDs on my STR by coming into the back and there was no way in hell I could get my hand to bend 90° into the housing and then there was no way the my finger tips would be able to release the connectors and the bulb latch. Ended up having to take the bumpers off and remove the headlights assembly to do it right. Then some guy on the STR Facebook page tells me he can replace the bulbs without removing the headlight assemblies and he does all the time and that was easy. I called hogwash

 

Its tricky but I have done mine several times in just minutes, but I am a mechanic and have those 3 extra joints in my fingers!

 

My headlights were always going out from getting banged around. My dad also resorted to a coat hanger to get to the clip and it now just lives permanently in the engine compartment for that purpose.

I am curious if anyone has ever found a way to keep the headlight assembly from breaking in the first place, since I'm now the owner of a car with still secure headlights

 

Why such bad words for Valeo as X-type headlights are made from Hella

novium what do you mean with "a way to keep the headlight assembly from breaking"? Do you mean the inner adjusters?

 

I'm not actually sure about the proper wording, but there's something plastic that's supposed to hold them in place that breaks and then your headlights go all crooked and also bang around and it makes you go through bulbs like crazy.

 

Fix the underlying cause =

 

Thanks! Is that for preventing the problem or fixing it after it occurs?

 

It is. I have replaced more than 50 pairs and they are all fine. The material they are made off is different than factory one and they do not brake like the factory ones.

 

They are Valeo units, not Hella, as far as I am aware.

 

Hella part numbers for left and right headlight.
