Unlike traditional BMW engines, modern engines, like the B48 and B58, use a volume-flow-regulated oil pump. Instead of providing a consistent volume of oil, these new systems control oil supply at each individual operating range.

This Control Valve Solenoid is a critical component in the volume-flow-regulated oiling system. This piece seamlessly adjusts the oil pressure based on inputs from the DME. In the event of failure, this means the engine oil supply system may become restricted.

Thankfully, Bremmen Parts offers this high-quality, OE replacement Control Valve Solenoid at a fraction of Genuine price. Built with durability and fitment in mind, this component is an exact fit for your BMW.

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.

Rocker arms work in conjunction with your camshafts and valves, applying pressure from the camshaft to open and close your intake and exhaust valves. If your rocker arm rollers have failed, this can lead to extreme camshaft damage, requiring the camshaft to be replaced. Replace your rockers whenever servicing your camshafts or replacing your hydraulic lifters to ensure long-term engine reliability.
