Dead Car Suggestions Please?

[Prudie]

I'd not driven my car since Friday afternoon and when I went to go to work this morning:
Neither remote fob (normal and spare) would open the central locking had to open with the key (would that leave the immobiliser active -??)
Key in ignition - totally dead, no lights, absolutely nothing

My first thought is a catastrophic battery fail, I had to get a lift to work and can't look at it until this evening but what could this be? I can't think anything left on (light etc) would flatten the battery to zero in a couple of days?

Prudie, when you put the new battery on the next step is to get an auto electrician to check the charging system and also check that something isn't draining it.
15 months isn't very old !.

Get the Alternator checked , it only takes a few minutes at a garage, if it is the alternator a new battery will not be any use as it will just go the same way. It does sound as if there is a charging fault so that the battery is just not being fully charged. When they check the alternator they will check the battery as well.

Just to give you an update for those interested. Took the battery out and it charged back up to full 12v overnight and started the car regularly today. I've taken it to a garage tonight who have confirmed battery fine and alternator working. Now to find out what drained it. The interior lights look like the number 1 likely culprit.

Well done, Prudie. The boot light and under bonnet light ( if it has one ) could be likely suspects to.

I have a BMW 2006 year (series 6) and after a while driving I can smell fumes inside, giving me a headache. Reluctant to drive too far now due to this. Any ideas why?

Can you smell petrol, Daca ?.

Could it be a small hole in your exhaust system near the front allowing fumes to come in through the airvents??
