EGO sensor #1?

I've never heard that terminology before, unless EGR, Exhaust Gas Return, was meant, which doesn't even relate to BMW because no BMW, to my knowledge, has ever had an EGR valve or assembly.

Mr. Bentley doesn't list those codes in the engine chapter.

O2 sensor or the sensor heater, exactly which stomp code do you have?

The 4-wire oxy sensor has a heater inside and heats up the system to a certain temperature. Till then the ECU works with a default value from the oxy sensor.

temp faster, this allows o2 sensors to start reacting much quicker than the early style that doesn't have a heater built into it.
