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

  Check the camshaft adaptation by reading off the adaptation values of the camshaft (flanks 1-4). All values must be between -7° and +7°.

  Turbocharged engines:  When checking, the accelerator pedal (AP) must be depressed slightly but the engine speed must be below 1200 RPM.

  Naturally aspirated engines:  When checking the engine must be idling.

  HINT: Theoretically the values for flanks 1-4 should be the same, however because of mechanical tolerances the values may vary between the different flanks by approximately 2°.
