x 5 code p0604 trouble
 

Hi Guys,
I just replaced my oil separator, I disconnected several wire plugs from the gray box leading to several relays, switches, under the intake manifold to access the separator. After I finished replacement, I re-installed all the plugs.
Now, I went to start the car, and it just turnss over ! I hooked up my scanner and there's a code- p0604- INTERNAL CONTROL MODULE RANDOM ACCESS MEMORY ERROR.
What is that mean ? Is there something I could do ? I'm stuck, does it gotta be brought (towed) to BMW?

Please Advise, Thanks in advance.

I doubt you caused this by disconnecting those sensors. I have done the separator twice, ICV once, and some other things, and had all those connections you mention off upwards of a dozen times. It sounds like your ECU needs to be reset.

If the car hasn't even started since you did the separator, it cannot have run long enough to get a pending code from one of them, and then get it again and turn it into a full blown fault code and flash the SES light.

I think this is something else.

Thanks, I found the problem, blown 30amp fuse in the engine compartment where the computers are. Now I got a code p0444, evaporative system circuit open ? Do you know where and what the PURGE valve looks like? That would be a great HELP!!!
