Hi I've just bought a 2011 xf diesel sport with a charging fault, have replaced the alternater and it's now charging the battery but still showing on the dash the battery warning light and in restricted mode, I'm getting 14.5 volts on the battery so is charging any ideas anyone.

There's a wire that runs from the BMS module on the earth post, to the positive terminal, that wire contains a fuselink, if it's blown or the wire is loose, the warning light will come on.

First thing is to reset the BMS you can do this with an icarsoft or SDD or live with it for a while when it will reset itself.
The voltage you have is fine. Check the voltage on the battery when it has been stood for a day or so. If it drops below
12.2 change the battery.
