Hi I have been a bit of a donut and let my MOT run out by a week or so and took to local garage. It failed due to the windscreen washers not working, so they replaced the washer pump [£134 not sure if fair], but they still could not get it working in the car. Pump was working fine connected up to machine but not in car, maybe working every few times they had a go but not all the time to pass MOT. They mentioned that it could be an issue with the body control unit which could have been from previous pump leaking and shorting it inside. They've suggested taking to Jaguar, however there is an independent Jag specialist I usually use for any servicing etc. I am picking up this afternoon and taking to them, having spoken to their receptionist, she advised lots of issues with BCMs on late 2012 & 2013 onwards for XF. Mine is 62 plate so guess I am lucky enough to be in this, she said they eat through these parts and Jag don't always give out all the codes so you have to go back. Has anyone had similar problems to this and can advise what sort of costs I could be looking at? I only bought the car September 2022 and love it but I've had a couple of issues since buying and starting to worry.

Hi all apologies for the delay in responding. Took it to local jag specialist, they diagnosed it as being the fact the battery was replaced by last owner approx a year ago and not reset. They reset the battery to the car which fixed the windows, locks and folding mirrors [didn't even know these closed when you locked car]. Cost me £100.00 but at lease no replacement door / lock parts and am happy everything is tickety boo!

Not that I noticed, it is been in independent jag specialist near me today, receptionist said it was done ready to pick up and they would explain more but sounds like an electrical issue, mentioned resetting battery and driver pack? Will find out more later and let you know in case of any use.

Hi @Bigvic the windows do not go up or down using either the driver panel or the rear controls. Can't hear any sounds either when pressing. The other day it did come up with a very brief flash of battery light on screen but not since. Due to go in tomorrow so will see what they say. The lock thing sounds expensive, i've seen a video on youtube for changing but worried it looks quite involved for me!

@Tomato did you try this out and did it resolve anything? My car is booked into garage thursday so just hoping they can take a look first before going ahead with anything.

@Tomato what is the battery trick?

Thanks @Old Peter will try some other resets this weekend and see where i am. @LunarGrape not seen this thing about the battery, have you tried it?

Hi Peter Thanks for your reply. Seller tells me new batt fitted in last year so wondering if linked. What do you mean by checking the numbers on radio? Also have two other issues relating to rear windows not opening and rear doors not locking which maybe are linked to batt too. Taking to independent jag specialist next week to see and might buy a fault code reader to check. Car is in great condition otherwise and reduced payment accordingly.

Hi, new to the forum, I have a 2012 XF which I bought recently and stupidly did not check the rear windows went up and down. The front two are fine, but I also have noticed they had manually locked the back doors, again did not check this because I am an idiot... Speaking to the previous owner who was selling on behalf of his father in law, they had a new battery put in a year ago so thinks it could be to do with that? It seems more than a coincidence that both rear windows don't go up and down and neither do the doors remote lock. It is not a major issue right now as I can set rear doors to be locked and don't use rear windows but has any one else had either of these issues?
