Camshaft adaptation, flank x

Measurement range between -20° to +20°.

The value stored in the control module for adaptation of the camshaft shift angle (flanks 1-4). 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°.

The value indicates how much the control module has adapted to the position of the camshaft, i. e. the deviation between the 0-position for the camshaft when camshaft control is not active (the camshaft's 0-position = the camshaft position set alignment in relation to the crankshaft TDC (0°).

Normal value is between -7° to +7°.

Turbocharged engines: The value must be controlled at an engine speed above idling speed but lower than 1200 r/min.

Naturally aspirated engines: The value must be controlled at idle speed.
