Hi All:

I have BMW X5 e53 2005.
I am running into the problems with fuel trims. Sensor 2 on both banks show --% .
I did replace all 4 Brand new OEM Oxygen sensors and still shows these values. Primary problem i am having is the Oxygen Heater Monitor is not getting finished. That led me to replace all 4 New sensors. Please help with ideas.. ?
** NO CHECK ENGINE CODES and car runs great.**

The OBD2 scanner shows
Short Term Fuel Trim (B2-S2) ---%
Short Term Fuel Trim (B1-S2) ---%
Short Term Fuel Trim (B2-S1) 6.2%
Short Term Fuel Trim (B1-S1) 6.0%
Oxygen Sensor Output Voltage (B2-S2) 0.755v
Oxygen Sensor Output Voltage (B2-S1) 0.160v
