1. Heated oxygen sensor 2 (G108) with oxygen sensor 2 heater (Z28)

2. Oxygen sensor 2 after three way catalytic converter (G131) with heater for oxygen sensor 2 after catalytic converter (Z30)


• Tightening specifications: 55 Nm

• New oxygen sensors are coated with assembly paste; the paste must not get into slots of oxygen sensor body.

• For a used oxygen sensor, only coat threads with hot bolt paste. This paste must not come into contact with oxygen sensor slots.

• Wiring connection of oxygen sensor must always be secured in the same position when installing so that contact with the exhaust pipe is avoided.
