Hello Guys,

Just wanted to share a problem that we have managed to fix on two L663 Land Rovers which have had the same issue of the SOS Limited Functionality error on the dash.

Both of these came back to the Telematics Battery (Back-Up Battery) that is located in the Telematics unit. After successfully changing the battery and clearing the faults there were no error messages.

The location of the Telematics is different for the 3 door and 5 door and accessing them is slightly different.

The battery itself is only £25 which is relatively cheap and the whole process shouldn't take longer than about 40 minutes.

Here is a video of the repair for both the 5 door and 3 door version.


Hope this helps!
