1. Carefully unscrew oxygen sensors at the primary catalytic converter.

Installing oxygen sensor behind catalytic converter
1. Grease thread of oxygen sensors with Optimoly Paste MF (000 043 207 07) before fitting them. Make sure that the paste does not get into the slits in the sensor body
2. Position the oxygen sensor by hand and screw in as far as possible.
3. Tighten oxygen sensor using special tool (e.g. open-end/ring wrench Nr.98 ). - Tightening torque: 45 Nm (33 ftlb.)±5 Nm (±3.5 ftlb.)







Subsequent work
1. Install primary catalytic converter.
