The Vanos system uses a special helical gear system between camshaft gears and camshafts themselves to progressively time the motion of intake and exhaust valves. Older systems just used mechanical friction to open and close valves, in which timing was determined by the size of your camshafts. Introduced in 1992, the Vanos times the opening and closing of fuel intake valves to make your engine work as efficiently as possible. The BMW Vanos is a proprietary valve timing system used by BMW cars and SUVs.

The typical price range is between $300 to $800. Overall, you can expect to pay about $600 on average to replace a BMW Vanos solenoid.
The Vanos system uses solenoids to control camshaft motion, which can wear down over time and need replacing. Part of this performance can be attributed to precision engineering, including the Vanos valve synchronization system. BMWs are known for many things including their engine performance.
