- Release the electrical wiring for the front
Lambda sensor from the retaining bands
and remove the sensor.
Refitting
NOTE Apply special grease (e.g. Bosch VS
14016- FT) to the threaded part ot
the sensor
- Place the Lambda sensor in position and
tighten to torque.
E Lambda sensor : 4.5 daNm
Reverse the order of the operations de­
scribed for the removal.
REMOVING-REFITTING REAR LAMBDA
SENSOR
Removing
- Position the vehicle on a lift.
- Disconnect the negative battery terminal.
1. Disconnect the electrical connector (1a)
and release the electrical wiring from the
retaining bands.
- Raise the lift.
2. Undo the lower fixing bolts (1a) and the
side fixing bolts (1b) and remove the
shield (1c) under the engine.
3. Use tool USAG 875 (1a), shown in the
diagram or a similar tool to undo the rear
Lambda sensor.
Refitting
NOTE Apply special grease (e.g. Bosch VS
14016- FT) to the threaded part of
the sensor.
- Place the Lambda sensor in position and
tighten to torque.
E Lambda sensor: 4.5 daNm
Reverse the order of the operations carried
out for the removal.
