BMW X5: Emission Control, Oxygen

REPLACING LEFT OXYGEN CONTROL SENSOR (N62/N62TU)

Special tools required:

(cylinder bank 5 to 8)

Necessary preliminary tasks:

WARNING: Scalding hazard! Only perform this task on an engine that has cooled down.

Unlock and detach plug connection (3).

Unclip control sensor cable.

Release control sensor (4) with special tool 11 7 030 in conjunction with 11 9 150.

Emission Control, Oxygen
Fig. 737: Identifying Control Sensor

Installation:

Threads of new oxygen sensors are already coated with Never Seez Compound.

If the oxygen sensor is reused, only apply a thin and uniform coat of Never Seez Compound to thread.

Oxygen sensor section projecting into exhaust system branch must not be cleaned or come into contact with lubricant.

Installation:

When special tool 11 9 150 is used in conjunction with special tool 11 7 030 , 47 Nm on the torque wrench dial corresponds to an actual tightening torque of 50 Nm.

Tighten down control sensor (4) with special tool 11 7 030 in conjunction with 11 9 150.

Tightening torque 11 78 1AZ.

Pay attention to cable routing of control sensor.
