Installing
When installing, note the following:
  Note
t  Threads of new Lambda probes are already coated with assembly paste; the paste must not get into the slots on the probe body.
t  In the case of a used Lambda probe grease only the thread with high-temperature paste. The paste must not get into the slots on the probe body. For high-temperature paste refer to → Parts catalogue.
t  When installing, the Lambda probe wiring must always be reattached at the same locations to prevent it from coming into contact with the exhaust pipe.
