electrical problem?

[phaust]

Hi group! didn't post for a few years!

I currently have a problem with my E60, seem like an electrical problem.

here is the problem.

when I open the door, the cluster light are on for a few sec then it's like the car went off. no doors lights etc.. but I can start the car no problem and hesitation.

I can't open the doors with the touch of the door handle. but I can with the key buttons.

the battery is new and there is no msg like " high battery discharge" on the computer..

someone have already saw this problem? didn't find anything on the board yet but I'm not sure if I searched for the real problem at all.. wires?

the car is a M5 2008 (manual transmission)

thanks guys!

edit: the battery is 1 year old and have been tested for this problem ( if there was any problem with the battery they checked this part) no loose wires for the battery too and the problem is there for about a few months. so was not due to battery change.
