Hi, I have a strange issue on my 2013 2.o diesel X1.

It has been runniing fine for years until today when we tried to start it was dead.

Tonight i jumped it straight away but now when you start it the lights are on all the time but the windows dash lights and other electrical functions do not work .

Now I have run it round the block the battery which is only 6 months old it starts the engine no problem.

Any ideas ? could it be an emergency get you home mode as the lights work

Morning Gary

Welcome to the Forum

Even a relativley new battery can die fully charge the battery (make sure you use the charge points under the bonnet) measure the voltage engine off key out at the charge points it should read 12.5 to 12.8v below 12v is either dying battery or a dead short somewhere. 

Once battery is at full charge engine running measure again you shouls see 14.8v indicating a healthy alternator. Engine off key out let the car go to sleep (takes up to 10 mins) then measure amperage at the under bonnet charge points you should se a few milliamps (clock, memory items etc) if your seeing higher you have a paracitic drain which will need tracking down. Check the starter motor a failing one can kill a battery really fast

Hope this helps
