Vanos Valvetronic Operation N62
Does anybody have knowledge of the hot start mapping of vanos and valvetronic and what is normal?
I have noticed when engine is fully warmed up, vanos has the cams at full duration (120°) and valve lift is at maximum (9.85) for approx 2 minutes after every start, then drop to 0.8mm lift and 80° duration on the intake side.
I would have assumed if oil/water temps are at normal operating level then (0.8/ 80°) should be an instant change by the DME.
