Hi all,

I've currently got a couple of little issues with my XJ. Nothing too serious, but it was an excuse to buy myself one of those iCarSoft readers.

A few errors which it's thrown up that won't go away.

B11ED - Electric Heater Control Unit
I believe this is to do with the electric boost heater. This makes sense, as unlike my XF's this doesn't seem to heat the car immediately. Not a big issue, as the car warms up fairly quickly anyway. But am I right in thinking that most likely this is a boost heater replacement? If so I may leave this as I think that's a fairly big job and requires draining the coolant and air-con, as well as removing the steering column etc. Any ideas of quick things I can check though just in case? I can't seem to find a fuse which applies to this.

B110A - Rear Door Driver Side Central Locking Motor
So the rear passenger door has been playing up. It locks perfectly fine manually, just not remotely with the central locking. I don't tend to have people in the back of the car often, so I've kinda forgotten about this one. Looking at the manual, this seems to be an issue with a short-to-ground. What's going to be the easiest fix here? Just replace the lock?

C2006 - Left Actuator (Powered Boot)
The powered boot worked perfectly when I first got the car. Then one day silly me left the boot floor clipped up and accidentally caught the button to close the boot. Since then it was hit-and-miss for a while, and finally, it gave up together. I did replace the powered strut a while ago to see if that would fix it, but it didn't. Any ideas about what may be the issue here, and how to fix it?


Finally, something which doesn't show up as an error, but bugs me anyway. The windows. They all seem to do this now. They go down with no problem. However, when closing, they go up about halfway and then go back down. I have to do this 3 times and then eventually it allows me to hold the button to close them fully. The fact this is happening on every single window makes me think this may be a common (and hopefully easy) issue to fix.

I think . . .

The rear door locking mechanism probably needs to be replaced. A common failure.

The boot may just need resetting. Hitting an obstruction while closing shouldn't have broken anything. When it's open, see if you can push it open any further and then close it.

Windows. Just reset the one-touch open/close setting. Instructions in the handbook.

Electric heater: No idea. But FWIW, mine doesn't seem to do much either.

The boot I think I may have narrowed down to a faulty module. Because I’ve noticed the soft close can sometimes be a bit hit and miss too lately and I have to reopen the boot and close it again. Both of these work off the same module. Fuse is fine. It’s only a £20 part so worth a punt. Does anyone know how to access it though. The part I thought it was is actually the parking brake module.

Also with the booster heater, I figured it’s worth checking the fuse for it just in case. According to the electrical diagram it’s a 150A mega fuse in the engine fuse box. Can’t seem to find it though. Only a 100A one
