• Ignition off
• Reinstall the connectors, components etc.
• Start the engine.

  Read off the camshaft shift angle and the camshaft shift angle, desired value.

  Check at idle speed and at approximately 4000 RPM that the camshaft shift angle, desired value, corresponds to the camshaft shift angle to an accuracy of 3°. The difference between the values can be read off in the lower display.

  Carry out the check at stable engine speed (RPM).

  NOTE:

  Before the engine speed stabilizes, the difference between the values may be 3° over approximately 1 second. This is normal.

  If the values correspond with an accuracy of 3°, it indicates that the fault is intermittent. If the values deviate by more than 3° it indicates that the fault is permanent.
