My left outer tail light unit has a crack, and I've ordered a new one.
This is for a 2010 model XKR, so it's the LED version.

My question though is how I remove the unit.

Ive looked inside the trunk, and I see one nut holding the unit.

And then I also see inside a small lid in the trench betwen the body and the trunk that there is a lid. Behind that I see a connector.

So, is there any more nuts holding it, than the one I see?

And is there any other special things to observe while replacing the unit?

 

There are 3 nuts inside the trunk, plus some sort of clip close to the rearmost nut - you can see all of them marked in purple on the attached image. The main warning is:

Torque for the nuts is 2Nm.

 

Thanks for the info and picture.

That means I also somehow need to remove some of the lining.

And I'll try to be as careful aspossible with the front end.

 

To remove the lining ("Loadspace Trim Panel"), remove the battery cover, the lift-out floor panel and the spare wheel. Then remove the scuff plate and the side panel:



Installation is just the reverse - bolts should be torqued to 10Nm.

 

Well now,

The above information was very helpful, and there was no problem getting rid of the old one.

But then there was a problem.

I got the replacement from a place called S.N.G Barrat in UK. The part that arrived has the exact same part number on its sticker as my old one. But the are differently wired.

See the two included pictures of the connector.

Why is this? Can it be due to that mine is a very early build of the new 5.0 face lift. Can it some how use seome other connections in the body?

Mine is off course the new LED tail lights. Is there any difference in the connections between the previous non LED lights, and the new LED lights?

If someone could check this in some electrical charts it would be greatly appreciated

New unit:

 

The connector is called CA054 on my wiring diagram; however, the diagram only covers MY11, which is the correct year for your car but has nothing about later models. At least there isn't any indication that there are wiring differences between UK & European models. And, annoyingly, the lamp side of the connector has all black wires, so it's hard to determine what has changed.

The wires on the other side of the connector (on the end of the car's loom) will be as follows:

CA054/1 LH_TAIL_LAMP_CTRL GREEN
CA054/2 LH_STOP_LAMP_CTRL ORANGE
CA054/3
CA054/4 LH_REAR_LED_DI_CTRL ORANGE
CA054/5 GROUND BLACK
CA054/6 REAR_FOG_LAMP_CTRL ORANGE/YELLOW

If we can get someone to check the wires on a later car, we can probably figure out which ones have been moved around.

 

Thanks for the info, lets see if some one has any ideas about any newer versions.

I'll try also to see if I can find out what is what using a low amp power supply at work. Maybe I can get some idea what's going where. These are LED and no other electronics, so there should be no trouble testing around a bit.

I'll also check the colors on the body side of that connector and see if it is connected as your list.

I'm not sure if it is possible to move the pins around though. Usually these kind of pins require special tools to pull out.

So Investigation continues :-)

 

Apart from the typo (45 instead of 54) and I think CA054/4 should be Orange not Blue, the 2012 on cars look the same.

I wonder if the connector has been incorrectly assembled?

Interestingly the 4.2L cars have all 6 connections in use so it can't even have mistakenly been wired up for those.

 

Arrgh - dyslexia rules, KO?

And I must have looked at the wrong link on the diagram - 54/2 is orange, as you say. The RH one is blue.

Original now corrected.

 

There might be something wrong with this one. The supplier would get another one in from Jaguar in a couple of days, they will check how that one looks.

One more thing that might point to something wrong with the one I got is that my original one has a kind of seal/trim on top (black) (see picture). The new one does not. How about yours?

Tomorrow I will also take out the light again and compare it with your description.

 

The set of lights I ordered DID have the black trim

 

Yeah, that looks like my original ones. Where did you get these from?

And also if you still can see. As which one of the above shown connectors does yours look like?

 

I've checked the connector on the new unit I've gotten. And that one has an empty position on Pin: No 2, whilst on my car, and on the list above, the empty pin is No 3. So there has to be something wrong with the one I've gotten.

I'll get back to the supplier again.

 

Just to brief you on the final solution. It was as suspected a wrongly wired unit that I had recieved. This was discovered when SNG Barrat recieved a new one, and it was dirfferently wired.

They then directly shipped it to me, and that one worked perfectly.

Thanks for all the support in here

 

Thanks to the info in this thread I was able to replace the taillight on my 2010 XK in under 15 minutes. I really appreciate the parts diagram Ngarara!

 

PLS I WANT THIS TAIL LIGHT LEFT-HAND SIDE (DRIVER SIDE ) TO BE REPLACED


.

 

Without the lense they look very much like the ALC tail lights

 

Yes, I’d be setting it back to original, too. But it won’t be cheap.
