P0604 Bmw ECM Self Check Fault

code po444 is referencing a purge control problem. this could be a bad connection or a problem with the purge solenoid for the evaporative system(EVAP). this is controlled by the PCM to allow fuel vapours to be drawn into the engine and burnt from the gas tank under certain conditions. the p0174 is a lean running condition on bank 2 and p0171 is a lean running condition on bank 1. the lean running conditions could be O2 sensors, lean condition caused by bad fuel pressure, dirty injectors, bad MAF sensor, vacuum leak.

Hi,
Hi,
First thank you for help me for this problem.
I have 2004 530i bmw. mileage 118,250. The check engine (increased emissions) comes on after I serviced windshield washer.
Is there anybody run into this problem?

Hello! a P0604 is telling you that one of the control modules, the Integrated Chassis Management (ICM) module has an internal Random Access Memory (RAM) error....Take it to an authorized BMW dealer and have a diagnostic run on the module...May only need to be "flashed" (software re-load)...
