x 5 code p0604 trouble

[salvy]

Hello,
I changed my oil separator this weekend, while doing so I had to unplug all the sensor/switches coming from the gray box, (under the intake) after installation of the separator, the code p0604 came up, and it won't start now, Does anyone know why or does it have to be towed to BMW, I cleared it, but it returns everytime I crank it over. PLEASE advise. Thanks in advance!

There was a blown fuse in the computer box up against the firewall, next to the cabin filter, passenger side, with 4- 30amp fuses and 1-20 amp. I had done the battery trick already, Thanks for the advice.
