Hi Paul, I think John posted a picture of the saloon CJB, the Sportbrake one is a bit different in layout.

I have a picture of the Sportbrake version showing which connector that causes problems but don't have access to it until I get home, I'll try to remember to post it later for you.

This is one from a Sportbrake.

Not that I've ever experienced the issues when exchanging or just disconnecting the battery, if you're going to do the exercise of ensuring the system is truly asleep then can I suggest that you leave the key in the house when going back to the car. It will trigger at least one part of the car's...

This is a close up of the connector that causes a problem in the Sportbrake Paul:

Thanks PeteA, mine has slight corrosion on the bottom 3 pins on the blue connector on the bottom left, I would post a picture but still cannot find a way to do it, I also need to see if I can actually drive the car with all the errors shown on screen which I haven’t yet been able to clear

 

[PaulPrior]

Yes that’s the connector, I have some corrosion on the 3 pins on the left, does anyone know what these are for?, I currently just have low washer level which maybe causes the headlight pump not to run?, is that possible ?

 

[Horlicks]

If the level drops too low, only the windscreen wash operates.

What's the current state of play Paul?

Hi
So after cleaning the connector again with the proper stuff, borrowing an obd reader that would clear the alarms I could then set about looking at my initial headlamp washer problem, so all sorted now, for info subsequent disconnections of the blue one did not cause all the other alarms, so must have been the wd40, so thanks everyone for your assistance

If you're still having headlamp washer issues, have a look at this post

Here's what your looking for...

Thanks for this. This has highlighted a problem for me. I recently fitted a DashCam. My fusebox looks exactly like this. I have a 2012 3.0D Portfolio with the heated windscreen pack. I don't have a sunroof, but the fuse is there.... My owners manual does not tally with what I see in the car. Here is a graphic of what I have vs what is in the manual (highlighted in red). Can anyone give me what my correct fuse layout should be?
TIA!!

my car is a 2010/11 and my fuses are as you have quoted in red, seems you have lots of wrong fuses installed
My car has cooled/heated seats & keyless entry so I have fuses in 27 & 29

 

[PeteA]

My PDF owners manual from 2013 has the CJB fuses listed like this:

🤷‍♂️

Yours is a facelift isn't it @XF_luvva?

Yes, it's the 2012 X250 facelift. It had the CJB replaced. Could I have the wrong CJB fitted?

I can't see how, there's just a saloon and Sportbrake version with each having had revisions.. I was more curious as the picture you put up is vastly different to the extract from the manual I posted in terms of fuse positions and ratings..

Going back to this: "I don't have a sunroof, but the fuse is there...." I expect that new ones come 'fully populated' with fuses so that there are no c0ck ups on the production line, it also would be more costly to populate them per model/options installed, it would also be a nightmare in terms of part numbers..

Fuses are very cheap in comparison..

It does seem weird. I have spent a fair amount of time today looking up images of XF fuseboxes and nothing matches.

XF_luvva, I don't know if it is helpful.
I attach a picture of my original CJB. I have a 2013 XF Sportbrake.

Thanks Dirk. And here's mine:

Please remember that the saloon and Sportbrake CJB's are different..

Don't know how I stumbled across this, but:
