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.

Flat Tire Monitor FTM
Principle
The Flat Tire display detects a tire pressure loss
while driving and issues a warning if the tire pressure
has dropped.
General information
The system detects tire pressure loss on the basis
of rotation speed differences between the individual
wheels while driving.
