Hi all
I am a new member.
Sorry for the length of this but it sets out the entire story.
My 2013 XF Portfolio S saloon 3lts diesel auto has been working fine until recently with no known problems
I had not driven it much in the last 2-3 weeks due to illness. It stood outside.
On Monday 15th January 2018 I unlocked the car on the key fob, the car bleeped, the lights came on, the doors unlocked and the mirrors folded out as usual. When I pushed the stop/start button the screen alerted me to a low battery but the car started perfectly fine and I drove it all day without any problem. The stop/start/ eco system worked fine as usual. Every time I stopped the car I was able to lock it with the fob key without problem and the mirrors folded in on locking and out on unlocking and the alarm system activated.
On Monday evening I disconnected both batteries and took them into the house to give them a good charge. Instinctively I closed the boot without thinking that I would be unable to open it now that I had removed the power supply and I did not drop the rear seats first which would have given me internal access to the boot !!. All the doors were unlocked and the bonnet was closed [and not opened at all throughout this process]
I took the manual key out of the key fob in order to open the boot manually. I removed the PVC cover hiding the barrel and inserted the key. The lock was very stiff but after about 15 minutes or so of wriggling back and forth it finally moved and the boot opened. I subsequently sprayed WD40 into the boot key barrel to lubricate it.
The car batteries were then charged overnight and both read around 13.9v after charge.
In the morning I unlocked the boot using the manual key. It was still stiff to open and took some force. The eco battery was connected first. No issue. The main battery was then connected. The ground [negative] cable was connected first and on immediately on connecting the positive cable to the battery the car Alarm sounded and the radio came on. I stopped the alarm by pushing the unlock button on the key fob and turned off the radio.
I then sat in the car and reset the parking brake, the window up/down travel and adjusted the clock. The car then started fist time without any warning notices on the dash/screen.
I took the car for a test drive. I noted that the passenger mirror dropped when selecting reverse…as it did previously… so that was fine.
On driving away I noticed the following:
a) that the drive away locking no longer worked even after turning it on/off via the screen.
b) I was unable to lock/unlock the car when depressing the buttons on the dash board instrument panel.
c) When sitting inside the car with the engine running I was able to lock/unlock each door separately using the door locking leavers. However, on internally unlocking the drivers door it did not unlock any of the other doors as it did previously.
d) On turning off the engine and stepping out of the car and after ensuring all doors, boot and bonnet were closed properly I was unable to look the car by using the key fob.
The car therefore has a permanent fault, namely since replacing the batteries the car will not lock with the key fob.
The key is clearly talking to the car because after selecting “lock” on the key fob there is two bleeps which confirms that the alarm has activated but the bleeps indicates that a door might be open. You can hear a locking sound at the fuel filler door but none of the doors actually lock and the mirrors do not fold back.
The car is alarmed even though the doors are not lock because when you open any door the alarm sounds until you use the unlock button on the key fob to silence the alarm.
The only thing that I have done is
a) Remove, recharge and refit both batteries.
b) Used the manual key from the key fob to open the boot manually.
It seems to me that there is a good chance that the fault might be connected in some way with the boot/boot catch given that is the only part of the car I touched after removing the batteries but I am told that all inspections/testing carried out appear to have ruled this out.
There are no error messages on the dashboard of any nature.
I have replaced the battery in the keyfob [just in case] and the batteries on the car both read over 13.5volts
I have disconnected the battery for 20 mins grounded the positive cable and reconnected....no difference
My Local dealership is stumped and a jag specialist has had the car 2 days without finding any faults [including no fault codes show]
Any Idea's ???
