This Valvetronic variable valve timing actuator is designed to optimize engine performance by adjusting the eccentric shaft, effectively increasing or decreasing valve lift and duration as needed. By dynamically controlling valve timing, it enhances power delivery, fuel efficiency, and overall driving performance.

A failing actuator can lead to noticeable power loss, reduced performance, and an illuminated check engine light. Restore your BMW's performance with this premium replacement from Bremmen Parts, designed to meet or exceed OE specifications.

Features:

Exact Fitment: Engineered to perfectly match your BMW’s specifications for seamless installation. Durable Construction: Built with high-strength materials to resist engine heat, vibration, and wear. Precision Manufacturing: Designed to OE dimensions for accurate clearances and alignment. Optimal Performance: Restores proper timing and functionality at all engine speeds. Get your BMW back on the road with reliable performance and confidence.

This eccentric shaft is a vital component of your BMW's N55 Valvetronic system, responsible for precise control of valve lift. In the N55 engine, the Valvetronic system uses intermediate levers between the camshaft and lifters to adjust valve lift dynamically. These levers are actuated by this eccentric shaft, which is rotated by an electronically controlled motor under the direction of the engine computer.

Eccentric shaft failure is a common issue in N55 engines, often caused by inadequate lubrication due to extended oil change intervals. The most frequent failure occurs when the eccentric shaft gear wears down, leading to disengagement from the motor's worm drive. Symptoms include multiple fault codes, such as P1014 (Shaft Parity Error), P1017 (Shaft Sensor Plausibility), P1023 (Valvetronic Adjustment Range), and P10E1 (Valvetronic System No Travel Detected).

If your BMW is experiencing Valvetronic-related fault codes, a failing eccentric shaft could be the source of the problem. Opt for this premium direct replacement from Bremmen Parts to restore your Valvetronic system's functionality and ensure a durable, high-quality repair.
