Jaguar XK 2008 Convertible. Both the headlamp and main beam Xenon won’t work, the side light and indicator work fine. The RH side no problem . Any ideas please? There are two silver boxes on the headlamp assy I’m suspecting one of these seeing as I’ve changed the H8 bulb and the D1S Xenon bulb.

 

1. I'd get a decent diagnostics tool - iCarsoft seems to be the popular one for JLR stuff
2. Headlights harbour some 2000v - don't touch anything with the battery connected
3. Apparently the wiring is known to be a bit problematic - worth having a look at connectors and cleaning with electrical contact spray etc

 

Thanks wsn03 I think I'll invest in the diagnostic tool as you suggest. Fuses are ok and connectors cleaned.

 

You're welcome - I'm just getting deep into the electrics myself, and without the diagnostic its just a complete waste of time. I have the icarsoft 1 or whatever its called, just ordered the 2 version cause its no much more, really easy to use and gives lots of information.
Eg I now know I have no resistance at one of my bonnet actuators, so I'm getting a short or component failure on that circuit - not to hard to get to the bottom of it now I know that.
Just remember disconnect battery - 2000v I'm told can kill you or take the ends off your fingers

 

Luckily there's a big connector I can I can disconnect to isolate the whole headlamp assembly without euthanising myself. The version 2.0 looks reasonable and is on sale at the moment for 136GBP. Cheers!

 

Please let us know how you get on, keen to get as much electrics experience from these cars as possible

 

Will do, but will be a few days, I've ordered the wiring schematics online so I think I'll wait 'til I get those (if they're any good)

 

Hope this helps, sticky from this forum

Big delay due to waiting for eBay to deliver a Xenon power supply

After embarrassing myself and not knowing how the Halogen lights were activated. I.e. turning the steering wheel left or right. I realised I only had one fault, namely, the pax side xenon. Swapping the headlamp assys the fault moved with unit, I had already changed the Xenon lamp so it had to be the PSU in the photo. I bought one online and fitted it today. Success! Luckily not too expensive an exercise. One needs a Torx screwdriver to remove the PSU.

 

Fwiw, I always replace the bulbs and PSU in pairs... as I’m in there anyways and most probably the other will go at the most in opportune time. Glad it sorted. Yes, the active? Headlamps and cornering bulbs are cool... they were a little uncommon back in 2008...

 

Thanks Guy

i did replace the other Xenon bulb as the colours/ brightness were dissimilar. Both match now. I didn’t replace the working drivers side PSU . Thought that might be tempting fate. Cheers!
