One of the most notable and useful systems in BMW’s stylish and high-quality cars is the vanos system. A system capable of improving engine performance, increasing fuel efficiency, reducing pollution and improving driving experience. Now you might ask ?
what is vanos system in bmw in response, we should say that a system with precise timing control is the input and output valves that allow the engine to operate optimally at a wide range of speeds and working conditions. This will also increase torque at low and medium speeds, improve engine responsiveness, reduce fuel consumption and reduce engine pollution.
However, since this system improves the efficiency and performance of the engine and improves the driving experience, we are going to discuss in detail what is Vanos system in Bmw in this article, as well as the issues and problems of the vanos system in BMW cars. So if you’re interested in this, stay tuned.
What is Vanos ?
If we want to say in a simple definition what is vanos?, It can be said that the VANOS system, or variable timing system of valves, is a modern technology developed by BMW to optimize the performance and reduce the pollution of gasoline engines.
By controlling the opening and closing time of the inlet and outlet valves, the system allows the engine to operate more efficiently in a wider range of engine rounds. This is a definition that can help us better understand the answer to what is Vanos System in BMW . Of course, the Vanos system also has many benefits, including improved performance, reduced fuel consumption, and reduced engine pollution.
Vanos system in bmw uses a hydraulic valve and a sensor to control the position of the valve mill and optimizes the amount of air and fuel mixture by adjusting the valve timing.
It also has two types, including the single VANOS system, which controls the input part, and the twin VANOS system, which controls both the input and output parts.
In addition, it can be said in response to what is vanos system in bmw that the technology has been used in BMW gasoline engines since 1992 and has made significant improvements in the performance, fuel consumption and pollution of the engines.
Bmw vanos problems
The vanos system used in bmw cars gives these cars very high efficiency and performance. However, this system may also crash and surprise you. So we’ve looked at this in this section of the article what is vanos system in bmw. So bmw vanos problems studies show that there may be a number of common problems and failures in the system.
Some of the most important ones that may be accompanied by symptoms such as poor vehicle acceleration Limp mode check engine lighting cracking noise and uneven engine operation in position and some other things are:
1. Damage to the Vanos power plant
Familiarity with common VANOS system failures can help you better understand what is vanos system in bmw. One of these common failures is the damage to the Vanos power plant. It is an important piece that controls the oil pressure to move the spiral gear in the engine.
This piece is susceptible to breakdowns caused by broken orifice or clogging with contamination and sediment. Rubber or rubber-like materials used in the orifice of the solenoid valve wear out over time and operation, and may lead to the inability of the solenoid valve to regulate the flow of oil.
In fact, electric valve clogging can also be caused by oil pollution and reduce the ability to control oil pressure. Also, to prevent O-Ring failure and maintain the Health of the VANOS system, it is recommended that the O-Ring of the electric valve be replaced after every 80,000 kilometers (50,000 miles). Clean and tidy oil can also prevent electric valve congestion and wear and tear.
2. Making a sound like a metal rattle
The VANOS system in BMW engines is responsible for adjusting the timing of valves, consisting of parts for Gears, Millers, valves and Pistons. Now that the lack of maintenance and wear on these parts can lead to a metal rattle-like sound from the engine, known as the vanos Rattle.
This sound is usually detectable at lower engine rpm and when accelerated further. In principle, it is very important to prevent Vanos Rattle, to perform periodic service and timely replacement of worn parts, as well as to use appropriate and quality oil. In the event of this problem, worn and stained parts in the VANOS system must be replaced.
Of course, this requires specialization and mechanical tools and should be done by a specialist. It is also necessary to be examined by a BMW mechanic to accurately diagnose the location of the creation of vanos Rattle. So if you see the vanos Rattle problem in your car, it’s best to see a BMW specialist to check and fix it. It is among the most common BMW vanos problems.
3. Vanos system oilseed duct clogging
As we mentioned in previous sections of the article in bmw system what is vanos, the VANOS system in BMW engines is responsible for adjusting the timing of valves. The system uses oil to adjust the opening and closing times of the valves for different driving conditions.
To supply the oil needed by the VANOS system, an oily duct is used, which transfers the oil to various components of the system. But this duct may be taken over time and accumulate contaminants and sediments, causing problems such as slow acceleration, difficulty starting the engine, or even entering low power mode.
However, regular and timely oil change and oil filters are essential to prevent clogging of the lubricating duct. It is also effective to use high-quality oils in accordance with the manufacturer’s standards. In addition, you should see a specialist repairman if you notice any signs of cramps.
These are among the measures that can prevent these problems from happening and extend the life of your BMW VANOS system.
4. Failure of the Camshaft position sensor
Other bmw vanos problems include a failure of the camshaft position sensor. This sensor has an important breath in the operation of the car engine.
Because measuring the angle of the camshaft sends information to the electronic control unit (ECU) and the engine management module. This information is necessary to set the exact timing of the opening and closing of the valves and the correct operation of the VANOS system.
The failure of this sensor can lead to slow acceleration, sudden engine shutdown and engine warning light on. The reasons for its failure include burnout, construction defects, and physical damage. Failure detection and repair or replacement is done by a specialist repairman.
To prevent failure, it is recommended to perform periodic car service and use original spare parts.
Vanos Pump
You can’t answer the question in BMW what is Vanos system and not mention Vanos pump. The VANOS pump or variable timing system of the camshaft plays an essential role in BMW engines. The pump compresses the oil it uses with high pressure (up to about 100 times) to help the VANOS system adjust the timing of the camshaft. VANOS facilitates better air entry and smoke outflow from the engine by optimizing the timing of the valves, which leads to increased engine power and efficiency. It also helps reduce fuel consumption and reduce engine pollution.
In addition, possible problems with the VANOS pump include its Wear, which reduces oil pressure and reduces system efficiency. There is a need to repair or replace the VANOS pump if signs of failure such as weak acceleration or vibration are observed in a quiet lap.
To maintain the life and optimal performance of the VANOS pump, it is also recommended to use quality and appropriate oils and to provide timely periodic services. However, if you notice any problems with the operation of the VANOS pump, it is better to consult a specialist mechanic to check its condition. If necessary, it can be repaired or replaced.
Summary
In this article, titled what is Vanos system in BMW, we tried to introduce you to the Vanos system. A system that can effectively increase the efficiency and optimal performance of your BMW engine. But there are also always bmw Vanos problems that you can do well with a few tips and tricks to overcome these common Vanos system problems.
Also, as we said in this article, the VANOS system in BMW engines plays a fundamental role in optimizing engine performance and efficiency.
In fact, the Vanos system facilitates better air intake and smoke outflow by adjusting the timing of the camshaft and valves, leading to increased engine power and efficiency. Of course, it also helps reduce fuel consumption and reduce engine pollution. Of course, the VANOS pump also plays an important role in this system, as it helps the VANOS system optimize the timing of the camshaft by supplying high-pressure oil.
