I own a 2008 Jaguar XKR. I'm having a extremely baffling problem with my front passenger headlight assembly. It all started when I turned the right turn signal on and got a warning light stating that it wasn't working.. I changed the bulb and nothing happened I kept getting the warning and then I started getting warnings that the Adaptive lighting system had failed. Overtime sometimes the headlight would work and sometimes it would not other times the turn signal would work other times it would not.There were days when nothing would work and then days where everything worked. It got to the point where it just quit all together not a single light comes on. My mechanic has looked at it and is unsure what the problem is. A new assembly from Jaguar is $3,000 which is ridiculous but thats another issue. Does anyone have a clue what the real problems might be? Please don't say replace the bulbs I have and they work sometimes and they don't work other times so that is not the problem. I put a new headlight balast in and it didn't change anything. There looks like there is a second balast or something in ther as well. Does any one know what that does?

Does anyone know if you but a used headlight assembly from an xk that doesn't have adaptive lighting, if that will work or will it throw a warning light.

 

Most likely a ground problem, I had the problem with my driver side with a corroded bolt/lug. The passenger side ground (for the passenger side light) is accessed by taking the wheel off, as the G06 is farther back you may need to remove the wheel arch cover.

This the thread I posted about my issue:

G06 location and wiring diagram:

 

Very well could be a faulty module , swap the modules over from the light that does work...if no change you can rule that out .... if fully functional even better you know what it is.

In order to swap modules over both headlights need to be removed, it's quite easy no bumper off or anything like that

 

If it isn't a ground, the insulation on the wires in the headlight breaking down seems to be another common issue with these cars.

 

Like so Lol ...if you go down this path you'll need to heat up the headlight and split the lense from the housing

 

Wiring inside the housing should be inspected via the rear of it. Lots of cars with DRLs are having issues due to cracked wiring insulation.

 

IF you've got the AFS system fitted, you must use AFS headlamps on both left and right or the headlamps will not function correctly.

I believe your issue's likely failed wiring insulation as noted above and you've got wires inside the assemblies shorting. Time to remove the headlamp, easy to do and look inside the rear cover and inspect the wiring. Several threads about this on these forums.

Why would jaguar design somthing where if just one wire fraed every light would fail. The headlight, turn signall, runing light , and whatever that 4one does all not working.

 

How can you test to see if it is the graound?????
Others say insulation but why would jaguar design somthing where if just one wire fraed every light would fail. The headlight, turn signall, runing light , and whatever that 4 th one does all not working.

 

Not likely a ground.

Read the thread I posted above and you’ll see what’s going on.

This issue’s not unique to Jaguar, it’s the manufacturer of the headlamps. Other marques have the same issues. These are old cars now.

Once the wires start shorting the headlamp’s going to malfunction.

 

You’re in denial. But once fixed you will be back on board.

 

a single wire could be the one that causes this. Lets say the insulation on your ground wire is shot, that would basically make your headlamp unit inoperable. When you expect a manufacturer to be perfect and never failing, you’re gonna be very disappointed. How old are you? You sound very young or very old, like 97 yrs old. There are ways of finding out whats wrong, but it requires actual inspection. Not some magical internet answer,

 

Why give me a back handed insult? The wires have been inspected by a mechanic and by me twice. I have replaced the balast as i stated in my original post.I apreciate those that are tring to help with out being condesending.

 

So you've removed the rear cover of the assembly and the internal wiring's in good condition? If so, that's surprising. This's what my 2008 original wiring looked like last year, even with no use, sitting in boxes for 5+ years, the wiring failed.

 

It's not just one wire associated with the ground point on the chassis, there are five wires (see pic below) going from the headlamp to the grounding stud on the chassis as per the wiring diagram. I posted in post #3. - this is common practice. Your mechanic needs to look at the ground points on the chassis.You can do this your self

Easiest way would be to visually check the ground points, you could strip part of the insulation on each ground wire in the headlamp and do an ohm meter check to the chassis for continuity.

 

I replaced a passenger side xenon in my 2009 last year, wiring in very good conduction, it's possible a batch of lights went out with crappy insulation.

 

Thank u so much for the info. You are right it is the ground wire. Looked behind the wheel and it was just hanging there. Taking the wheel off tomorrow for closer look. Looks like it might have broken off from the frame. Not sure what to do if thats the case. Again thanks for your help.

 

What I did was drill a hole, tap the hole and refasten with a bolt - I also covered the connection with paint to protect it from moisture. Make sure you use the right drill size for the tap, the frame is not really thick so be careful when tapping the hole, there won't be a lot of threads after you are done. I think I used a 5/16 of maybe 3/8 bolt.

 

sorry about hurting feelings mate. I was just trying to figure out your age due to how expressed your frustration. Hope all the help gets it all fixed for ya
