    Just because the battery is only 4 Weeks old is no guarantee. If the Alternator is no charging it, it will go flat/drop volts and then all sorts of spurious messages appear.
    If you can start the engine, look for at least 14.5V at 2,000 RPM with EVERYTHING switched on.

    This section is really for feedback about the LZ site, not tech help.
    @blue beasty could this be moved to the correct place please?

    Not on a diesel, diesel charge rate is 13.8 unless the controller has been changed.

    Except possibly on late ones I think, but as you say the alternator regulator may well need to be changed and his problem could be a dead alternator.

    Put a voltmeter across the battery it should read as above 13.8v on the diesel if the Alt is working
