Genuine BMW 11-72-7-838-028 VANOS Solenoid Control Valve

The Genuine BMW 11-72-7-838-028 is an OEM VANOS solenoid control valve designed to maintain precise operation of BMW's variable valve timing system. This solenoid regulates oil pressure flow to the VANOS actuator, allowing the engine control unit (ECU) to continuously adjust intake and/or exhaust camshaft timing for optimal performance, fuel efficiency, and emissions control across the full RPM range.

As a Genuine BMW part, this control valve is manufactured to the exact tolerances and specifications of the original component installed at the factory, ensuring a direct, no-modification replacement. Using a genuine OEM valve eliminates the risk of fitment issues, premature wear, or fault codes that can arise with aftermarket alternatives.

Key Features:

• OEM Genuine BMW replacement VANOS solenoid control valve
• Regulates oil pressure to the VANOS camshaft timing actuator
• Enables dynamic adjustment of camshaft timing for improved power and efficiency
• Direct factory-spec replacement — no modifications required
