Have a 525i 2001 model and the problem is that I can not open the front doors with remote control (tried both keys). Had another problem earlier that all dashboard instruments were dead (happened 3-4 times)but now OK (so fare). Is the problem in the computer?? Is there more than one computer in this car??

tried both keys... Can open driver door only manually, passenger door can not open...
There are many control units fitted to this car they all control different functions around the car.
The instrument cluster is a small computer itself.possible dry joint if all working ok now.
The door locks are controlled by a door lock module called the ZKE unit this also controls windows and alarm functions etc.
I suspect both problems are not linked to each other.If both door locks are not working the only thing you can check is that fuse 6 & 29 are ok.
