Function
Actuation of the adjustable camshaft timing solenoid takes place map-controlled via the ME-SFI [ME] control unit (N3/10).
The adjustable camshaft timing solenoid integrated in the oil circuit guides the engine oil, according to actuation, through the ME-SFI [ME] control unit (N3/10), via the oil pressure line "advanced" or the oil pressure line "retarded" to the camshaft adjuster.
Excess engine oil in the engine oil circuit is led back via the return on the adjustable camshaft timing solenoid.
