Checking lambda control
Removing and installing lambda probe

  • ‒ Undo cable ties.
  • ‒ Use V.A.G 3337/9 to unscrew lambda probe.

When installing, note the following points:

Notes:

  • ◆ When installing, the cable ties must be re-fitted at exactly the same points in order to prevent contact between the Lambda probe wire and the exhaust pipe.
  • ◆ Tightening torque 50 Nm.
  • ◆ The screw thread on the lambda probe is coated with assembly paste. This paste must not be allowed to penetrate the openings on the probe.
