Genuine BMW VANOS Solenoid Valve, BMW N55 / S55

The Genuine BMW VANOS Solenoid Valve is a critical component in the variable valve timing (VANOS) system for the N55 and S55 6-cylinder engines. This solenoid valve controls the variable timing of your camshaft, with one solenoid required per camshaft (2 for 6-cylinder engines). Key Features and Functions: - VANOS System Control: The solenoid valve drives the VANOS system, ensuring precise timing adjustments for optimal engine performance.- Performance Impact: A failing solenoid can result in the VANOS system ceasing to function or responding slowly to ECU commands, leading to noticeable issues such as loss of torque at certain RPM ranges and decreased fuel economy.- Diagnostic Indicators: Symptoms of a failing VANOS solenoid might include a check engine light, fault codes related to VANOS control or operation, reduced power, or the engine entering limp mode. Experienced mechanics with the appropriate diagnostic tools can accurately test and confirm VANOS system issues. Product Details
