Hi.

I have a 2014 XF Sportbrake 2.2D R-Design. Until recently everything was fine however I've started experiencing some electrical problems.

1. Rear passenger door will not open
2. Audio/phone pairing doesn't work
3. Parking sensors audio feedback not sounding
4. Stop/start is active but doesn't actually stop/start

I have replaced both the main battery and the auxiliary battery and nothing has changed other than the stop/start feature is available even though it doesn't actually work.

The fuses listed in the manual do not align with reality or even any online pictures I have found.

I have also connected an OBDII reader and there are no fault codes. I have an appointment with Jaguar booked for late Nov and they are going to do diagnostic tests but if there is something I can do to diagnose problems to avoid the costs beforehand then that'd be great.

Given the passenger compartment is where the manual says the fuses for most interior features are I have included a photo for advice.

Any ideas welcome.

1. probably a failed latch, it's very common - can you unlock/open if from the inside?
2. Did it work before with the same phone? ( also check for water ingress under the passenger seat )
3. Have you checked the volume level for them in the menus?
4. Did you inform the cars battery management systems that the batteries where changed ( with a suitable diagnostic too )?

A generic OBDII reader will only show engine faults, you need to get something like Autel AP-200 ( no postfix ), which will show you full length codes from all modules, as well as live data, and allow you to "reset" the BMS for you new batteries etc.

 

Hi Sportbrake Phil. 1. The rear door wont open at all from inside or out.2. All of the phone connections was working with the same phone until recently. I have noticed it is quite misty these autumn days on the inside so I will check for damp under the passenger seat.
3. The volume level is fine, there is just no radio stations nor sound at all. The audio looks like it is off but is in fact on because switching the audio on and off changes the display to say audio on or audio off when you press it.
4. I didnt change the batteries myself but i will check with the garage who did tomorrow.

As the for the OBD, I'm a novice so didnt know that so thanks. I will ask at the garage and if all else fails i may invest.

Hmm, that door lock is going to be a pain to deal with, probably have to take the back seat out to get the door card off, and then work out where to drill/cut the mechanism to release it ( as they are screwed in from the door edge )

Have you checked under the floor in the boot for any signs of water ingress?

 

I haven't gotten around to checking for water ingress just yet however I find I can open the door if it is unlocked manually from the inside.
I have a better OBD reader coming today as the garage said Jags don't have a new battery thing unlike German cars.

I will get around to checking for damp later this week.

 

Lol, yeah they have two, one for each battery.

 

Thanks Phil.

I got the Autel AP-200 yesterday and hooked it up today and there are 2 faults showing:

1. FCDIM Front Control/Display Interface Module
2. Passenger's door module

Both make sense given the symptoms. I have checked for water ingress and can confirm no ingress at all.

Reading the Autel codes for FCDIM, I can see code U1A24-87 which states "MOST ring complete, no communication". The code for the Passenger's door module is B110B-15 "Rear door passenger side central locking motor".

 

That's an interesting code, I wonder why there is no communication if the MOST ring is complete, presumably means there's a bad module on it, but it is still working enough to forward messages to the next unit on the ring.

I imagine the other code is very likely a faulty latch mechanism in the door. Third party ones are pretty cheap.

You should be able to inform the battery management system of the new battery using the hot functions on your AP-200.

 

Thanks

Agreed. A garage I spoke to seems to think it's the Bluetooth module and is going to take a look in a couple of weeks.

I have just watched this and found this part (or this genuine part) and it seems pretty straight forward. So I might have a go myself.

i think i have tried but it hasn't made a difference, I might try again later.

 

If you look at the live data for the GWM, you'll find "Vehicle battery - Time in service - battery 2", that'll tell you how long ago the "battery replacement" for the small battery was done, it says the units are seconds, but they are days.

There is also "Vehicle battery - Time in service" for the main battery.

 

Interesting. Both batteries say 2623 s which, as you say, means 2623 days. The hot functions on the Autel AP200 doesn't appear to do anything. It simply changes colour - see image.

 

Yeah, when the hot functions just change colour like that they're not working. If you have an older android device I suggest you try that, hot functions work great on my old android 6 phone, but not on my up to date one.

 

So.

I changed the door module and nothing changed, I still can't use the key fob to lock/unlock the door. It wasn't an original Jaguar part I used but the one in place wasn't either; it was a Volvo part.

The Stop/Start is still not working even after the garage who changed the battery did a flash to say they had been changed. Could the FCDIM module play a part in this?
