BMW E39 – No start / no electrical power

Posted by Dave 0 comments

If you find you have no power to the ignition circuit, no warning lights on the dash etc. it would be very easy to assume that the immobiliser has developed a fault. There is an additional mega-fuse box hidden under the carpet in the drivers foot-well. One of the fuses contained therein governs power to the ignition and fuel pump circuits. It’s an absolute swine to get at and requires the drivers seat be removed. If one of the fuses has blown, check the mega-fuse box in the boot as some models often have redundant ones there that can be utilised.
