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.
