Hi all, my 2004 e60 m54 530i has got a problem. Problem is Central Electronics Failure. I cant access to car with ista and icom next. (Sometimes i can sometimes not)

Car engine works no problem with engine or crank. Wipers are working itself, locks of doors are not working properly. All lights coming to instrument cluster. Steering wheel is working hard. ONLY MRS-ACSM module no communication

I've checked that modules for corrossion;

CAS , AL , MRS-ACSM, DME, KBM(BCM), MPM, PDC

Checked All fuses and relays.

Whats the problem, no water any modules.

Many Thanks for replies.

What do you mean by "All lights coming to instrument cluster."?

What do you mean by "All lights coming to instrument cluster."?

Like abs light active steering light wiper light.

But i disconnected the kombi 5 minutes ago. No more coming electronics failure. Is this because of Kombi.

Now i ve got a problem with Active steering. I cant process control plan on service functions. I get error like "VIRTSG90_0x90"

You mean after disconnecting the kombi you can now access the car including ACSM? Did you disconnect the battery before disconnecting the kombi? And by connecting a kombi you get problems back?
