Oxygen Sensor (Turbo)

Dismantling







1 Open the bonnet.
2 Remove the cover over the throttle body.
3 Unplug the oxygen sensor's connector and remove it from the holder.
4 Snip the cable tie and withdraw the oxygen sensors lead.
5 Remove the oxygen sensor.

IMPORTANT
The leads must not be twisted. The oxygen sensor is highly sensitive to knocks and blows and must be handled with care.

To fit







1 Coat the oxygen sensors threads with Molycote 1000 (30 20 971) to prevent binding.

IMPORTANT
The oxygen sensor is sensitive to knocks and blows and must be handled with care. It is important to ensure that the connection between it and the nipple is gastight.
The oxygen sensor's lead must not be stretched between engine and exhaust pipe. Secure the cable to the clips so that a loop is formed just before the sensor.

2 Fit the oxygen sensor.

Tightening torque: 55 Nm (41 lbf ft)

IMPORTANT
Watch out for sharp edges, hot components, etc.

4 Secure the cable to the turbo's coolant pipe, using a cable tie.
