If you're not sure if your Vanos seals are bad then the only question you need to answer is if you've replaced them. Every unit from the factory came with the same failure prone o-rings and seals, even the re-manufactured units you can still get today. The only real fix is by replacing the seals and o-rings with material that is built to last in the oiled, extreme temperature environment found in these kits. 

A premium product replacement with easy to follow instructions makes rebuilding your Vanos unit a must. Even thought the power loss is barely felt it's the opposite result once you replace the seals, every car that gets rebuilt ends up wowing the customer and all of them saying they didn't realize what they lost. 

There are a number of symptoms that will plague your car as a result of these failing seals such as erratic idle, engine hesitation, stalling, and increased fuel consumption to name a few. If you've been chasing down any of these symptoms with no fix then this could be your issue.

These WPC-treated bearings are the best we have seen! WPC is a shot-peening treatment at a microscopic level. It's perfect for sensitive surfaces like bearings. The WPC treatment removes imperfections and high spots, while creating a surface that retains oil better than the original surface. This greatly reduces friction. The bearings in this kit are original equipment KS bearings that are sent to WPC for treatment. The treated bearings are stronger with less metal fatigue and less friction than buying off-the-shelf bearings from the dealer.

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.
