Vanos reference position offset ("one tooth off")

P0016/P0018, P0017/P0019

This diagnosis module detects a one-tooth error in camshaft to crankshaft alignment (e.g. by a slipped chain). If the adapted camshaft reference position exceeds an adjustable limit (one chain-tooth), a min fault is set (CDKNWEKW, CDKNWAKW or CDKNWEKW2, CDKNWAKW2).
