hi,
i have left on my interior lights over the last couple of nights and my battery is now flat.
the central locking wouldn't work so i opened the car using the key. problem is the battery is completely flat , i cant switch off the alarm, i cant open the boot to charge the battery. big question ; - how do i open the boot ??????

thanks in advance,

Ian.

ps. its a 1998 c180.

 

Hi i had the same prob last year on a C220 1999. under the bonnet there is a black plastic box where the bty power gose to conect another bty live to that and the earth to a good point on the car and that shouldgive power to your boot.

 

What he means is that underhood is a positive battery connection post. That will provide battery power with the use of a jumper battery.
