Where to Score Reliable BMW VANOS Repair in Humble?
BMW models are popular for their reliability and improved engine performance. One of the features that makes this possible is the VANOS system which helps to improve engine power at high speed and also improve fuel efficiency.
However, the VANOS system uses advanced technological innovation, which makes it easily susceptible to failures. To protect your car’s engine, you need to be able to identify the signs that point to a failure in the VANOS system so you can plan a repair before more damage is done.
The BMW VANOS System and Causes of Failure
In older models, the timing for the opening and closing of engine valves was fixed. However, most models needed flexibility, especially under different driving conditions. This led to the innovation that developed variable valve timing, however, with a compromise. Drivers mostly have to choose between smooth driving and better performance.
The Variable NOckenwellen Steuerung (VANOS) system, developed by BMW manufacturers and unique to BMW models, became a solution to this problem. This system allows the engine valves to open and close based on the driving condition. This helped to improve performance, fuel efficiency, and smooth car operations.
However, due to the complexity of this system, anything could go wrong, leading to a VANOS system failure. Here are some common issues that can lead to a VANOS failure in your BMW.
- Worn Out Components: This is a likely cause if you have had your BMW for a while. As your car ages, so do its parts and systems; with aging and frequent use, some parts of the VANOS system like seals can wear out, causing problems such as oil leaks which eventually damage the system.
- Debris and Dirt: Like dirt and debris clog water pipes, the same can happen to components of the VANOS system such as the oil feed lines. These lines help to move oil to the system and when it gets clogged by dirt or debris, there can be a problem. The VANOS system needs a clean supply of oil to perform its functions, when this is not available, it fails.
How Do You Recognize a VANOS System Failure in Your BMW?
Early detection of any system problem in a car can save you money, time, and effort. The earlier you identify a fault, the earlier you can get it fixed before any real damage is done. Here are some signs to alert you of a VANOS system issue in your BMW:
- Loss of Engine Power: One of the top signs you will notice in a BMW with VANOS system problems is a loss of power or poor acceleration. The VANOS system helps to improve the engine’s efficiency by aiding the opening and closing of the engine valves for optimal air intake. However, when this fails, the result is a loss of power as the combustion process is affected by a disruption in the air intake process.
- Check Engine Light: If you notice the CEL on your car’s dashboard, it could mean several things including a faulty VANOS system. If the engine’s control unit spots any issue, no matter how slight, that affects the engine’s performance, it triggers the CEL to come on so you can take a look at your car and fix the problem.
- Reduced Fuel Efficiency: If you notice that you are consuming more fuel than usual in your BMW over the same distance and you have confirmed that there is no fuel leakage, the next thing you should look at is the VANOS system as it can cause fuel economy problems. If the VANOS system gets faulty, it affects the air intake process in the engine, leading to an air-fuel imbalance. The eventual result of this is that your car keeps trying to make up for the problem by burning more fuel, leading to reduced fuel efficiency.
Other common signs are:
- Rough idling
- Unusual and loud noises
- Engine stalls in cold weather
- Poor acceleration
