BMWâs Variable Valve Timing system is called VANOS (Variable Nockenwellen Steuerung), and hereâs how it works! 1  The VANOS unit lifted off, notice how the cam and the cam gear are independent of each other without the VANOS gear in place. Image courtesy of Beisan Systems. This is the single VANOS engine (found in M50 engines). It controls the intake cam gear, which is mechanically linked to the exhaust gear with a chain. The key of the VANOS design is that the cam gear and the cam itself are independent, and both have splines. The gear/cup in the VANOS system inserts in between these two parts, mechanically linking them. The VANOS gear has two sets of splines, the outer for the cam gear and the inner for the cam itself. The splines have a twist to them, also known as a helical gear, so as the gear inserts itself further between the cam and cam gear, the relative position changes, if by only a few degrees.
Screws into the engine similar to the vanos solenoid. I had this same problem,p0012,and it was a clogged non return valve. The vanos solenoid is controlled by oil pressure,and adjust timing.if your non return check valve is clogged,oil can't flow to your vanos solenoid. I replaced my chain kit,no help,did my vanos,no help,dealer,no help, but one shop made an article about sending someone's cylinder head off to be machined,and left this little valve in,so when they got it back,the car was giving this same error message.
