vanos solenoid valve What does it mean

< span style="font-size: 16px;">The vanos system operates the intake camshaft depending on engine speed and accelerator pedal position. When the engine speed reaches the minimum, the intake valve will open later to improve idle quality and smoothness. When the engine is at medium speed, the intake valve opens early to increase torque and allow exhaust gas to recirculate in the combustion chamber, thereby reducing fuel consumption and exhaust emissions. Finally, when the engine speed is high, the opening of the intake valve is delayed again, allowing maximum power to be developed.

The vanos system greatly enhances exhaust emission management capabilities, increases output and torque, and provides better idle quality and fuel economy. The latest version of the vanos system is dual vanos, used in the new M3 models. This technology was first used in the M50 engine of the BMW 5 Series in 1992.

vanos solenoid valve failure symptoms

BMW's vanos system is a camshaft control unit operated by the vehicle's engine management system, combined with hydraulic and mechanical controls. The vanos fault may be caused by vanosSolenoid valve. Symptoms are that the engine malfunction light comes on, the vehicle cannot accelerate, the idle speed is a bit wobbly, and the central message displays "Unable to obtain full transmission power." Remove it and clean it first. If it still doesn't work, it needs to be replaced at a 4S store.
