Valvetronic Actuator for B58/S58 Engines

The Genuine BMW Valvetronic Actuator (part number 11377643073) is a crucial component for managing intake variable valve lift in B58/B58TU and S58 6-cylinder engines. This electric actuator, manufactured in Switzerland, precisely controls the intermediate shaft's position based on signals from the engine computer. As part of BMW's advanced fourth-generation Valvetronic system, this unit serves as both the actuator and the sensor, a consolidation that streamlines engine management. This actuator plays a vital role in engine operation. A failure in either the internal sensor or the motor can lead to a "check engine" light, potentially causing the engine to cease functioning. Common symptoms of a faulty actuator include a loud, rapid clicking noise from the valve cover, an unstable idle, and hesitations during throttle application. This Genuine BMW part comes with a two-year warranty, ensuring its quality and longevity. The Valvetronic system relies on this actuator to dynamically adjust valve lift, optimizing performance and efficiency. This Valvetronic Eccentric Shaft Actuator is compatible with a wide range of BMW models, including the 2 Series (M240i, M2), 3 Series (340i, M340i), 4 Series (440i, M440i, M4), 5 Series (540i), 7 Series (740i), X3 (M40i, X3M), X4 (M40i, X4M), X5 (sDrive40i, xDrive40i), X6 (sDrive 40i, xDrive 40i), X7 (xDrive40i), and Z4 (M40i) from model years approximately 2016 through 2026, depending on the specific vehicle model and engine configuration (B58, B58TU, S58). It is designed for engines with 3.0L L6 configurations.
