Hi guys,
I am having a few electric anomalies, AC kicking in when button is not pressed, drivers side mirror not dipping in reverse etc.
I think I read somewhere that the first port of call is a battery disconnect.
It is a 2013 XF 3.0 diesel. It seems to have 2 batteries but it's not a stop start model.
Do I need to disconnect both batteries and for how long?

Is there anything else I need to be aware of for example setting the vents to open, any codes that I will need to enter when connecting back up etc.

I would be grateful for any advice.

 

It is not advised to disconnect the battery of an XF 2012-2015. Well known issue - can lead to a corrupt BCM and render your car a non-starter.

You're best bet is to plug it in for a diagnostics scan to read the fault codes.

 

If you have 2 batteries you do have stop/start.........why else would you have 2 batteries???

 

Info here.......

 

That is good to know, I will certainly be leaving it alone now...
The only fault code I have is the temperature sensor which will be done on Friday.

 

TBH I didn't know that. I thought I had been through all the settings and didn't come across a stop start option. At the moment it is obviously not turned on.

 

Both batteries will need to be in top condition/charge for it to work. I don't have it myself so no real experience.
Iv'e read that if there is high demand (like AC on) then stop/start won't work as the AC would need the engine running to work correctly!

 

Just my 2 bob's worth, but I recently had my main battery replaced (I agree that 2 batteries equals stop/start), and, apart from needing to reset windows and a few other systems, everything worked well. I wouldn't shy away from battery disconnection, if it was needed.

 

I was hoping that would be the answer but it seems there can be a risk.
Did you have to use any codes on re connection?
What was the reset procedure, why the windows?

 

No codes were needed, I can't remember how to reset the windows, but it was simple. I'll see if I can find the procedure,

 

 

Thanks, MoJo88.

 

Any info on door locks not working? I just changed my main battery and now my doors will not lock. I can hit the remote button and hear it attempt but it does not engage. I tried from the door itself as well with no luck. My windows work fine. Thank you for any help you may provide.

 

There's a battery disconnect procedure, if not followed you can lose the locking. You will need somebody with Jag sdd to run immobilisation to recover the locking.

 

If not experienced in these matters with the battery just a friendly heads up, do not touch the battery, simply take it to jaguar dealer, bite the bullet replace the battery ,they will use sdd to reset everything, do not tell them you have any issues, just tell them to replace the battery and let them sort things out at the same price, works every time, no headaches
