VANOS is essentially a system that allows for variable camshaft timing. To understand its significance, we must first grasp the concept of camshafts in an engine. Camshafts control the opening and closing of the engine’s intake and exhaust valves, determining the timing and duration of these events. Put a towel under the bottom (exhaust) solenoid, and change this one first. Unplug the electrical connector, use a 10mm socket to loosen the retaining bolt, and once you can twist the retaining bolt by hand, CAREFULLY back the bolt out by hand. Twist the solenoid to the right and then pull straight out. Common VANOS problems & Diagnosing them. These are the most common symptoms and problems caused by a faulty VANOS system in your BMW.

The VANOS unit is basically a pump and solenoid that rotates the camshaft to make more torque at various RPM. Having a variable camshaft means the M3 S54 engine can make a lot of power in the high RPM without feeling too sluggish in the lower RPM. .
