Who Makes BMW Vanos Solenoid: Do This Engine Part Can Fail

If you’re the owner of a BMW, then there’s a good chance you’ve heard of Vanos solenoid. It’s an important engine part that helps control the valve timing on your car. But what happens if it fails? In this article, we’ll tell you who makes BMW Vanos solenoid and what can happen if it goes bad.

Who Makes BMW Vanos Solenoid?

The first thing to note about the BMW Vanos solenoid is that it was created by the German company BMW. It was designed as a way to improve engine performance by allowing for variably adjusted valve timing. This ultimately translates to better power and range for the car. It should be noted that this is an important part of any BMW engine computer. Many people don’t realize how crucial this component is to the car’s success. 

The Vanos solenoid is an essential part of any BMW engine computer and its proper function is crucial for peak performance. When troubleshooting issues with a BMW engine, it is important to check the status of the Vanos solenoid as well as other engine components.

How Does the BMW Vanos System Work?

The BMW Vanos system is a variable valve timing system that uses oil pressure to control the position of the intake and exhaust camshafts. The Vanos actuator is located on the camshaft gear and is controlled by a solenoid. The solenoid controls the amount of oil pressure that is applied to the actuator, which in turn controls the movement of the camshaft gear. 

By controlling the movement of the camshaft gear, the solenoid effectively controls the timing of the valves. The Vanos system allows for more efficient engine operation by optimizing valve timing for different engine loads and speeds. Additionally, the Vanos system reduces emissions by reducing engine knock and improving fuel economy [1].

How Do You Know If Your Vanos Solenoid is Bad?

The Vanos solenoid is part of your BMW’s Variable Valve Timing system. This system regulates air intake and improves combustion efficiency by regulating the timing of engine valve opening and closing. In short, it makes your car run more smoothly. Over time, however, the oil inside the solenoid can break down and cause the Vanos unit to fail. 

As a result, you may notice a drop in performance as well as increased fuel consumption. If you think your Vanos Solenoid may be going bad, it’s important to take your car to a trained mechanic for diagnosis and repair. Ignoring the problem could lead to long-term damage to your engine.

Can Vanos Solenoids Fail?

As any BMW owner knows, the Vanos system is essential for maintaining optimal engine performance. Vanos solenoids play a key role in this system, and when they fail, they can have a major impact on engine performance. There are several reasons why Vanos solenoids may fail, including clogged filters and worn-out seals.

In some cases, simply replacing the solenoid may be enough to get the system up and running again. However, in other cases, more extensive repairs may be necessary. Regardless of the cause of the problem, it’s important to get it fixed as soon as possible to avoid further damage to your engine.

Do All BMW Engines Have Vanos?

BMW engines have a feature called Vanos, which stands for Variable Valve Timing. This system uses both mechanical and hydraulic camshaft control mechanisms to optimize engine performance. The DME engine management system manages the Vanos system, making sure that it is constantly adjusting the timing of the valves based on driving conditions. 

This ensures that the engine is always operating at peak efficiency, providing maximum power and torque while minimizing emissions. Not all BMW engines are equipped with Vanos, but it is available on most models. Those that do not have this feature can still benefit from other advanced engine technologies that BMW offers.


We hope this article has helped to answer some of the questions you may have had about who makes BMW Vanos solenoid. It is important to remember that if you think your Vanos Solenoid may be failing, it is important to seek service from a trained European vehicle mechanic as soon as possible to avoid long-term damage to your vehicle.
