There are many helpful DIYs for taking apart and changing the vanos solenoids, but I’m having difficulties figuring out what products or techniques you guys use to really clean them. Can somebody provide further information about using brake fluid and letting it soak? I’ve read that some people do this.
I used compressed air and throttle body cleaner. however it didn’t work for me. One had to be changed because it was still producing error codes.
I did the same thing, but I also switched the upper one into the lower location and the lower one into the upper spot. I’ve driven roughly 3000 miles since then and haven’t experienced the problem once more.
Mine was just cleaned two days ago. Actually, I had to replace one because it repeatedly threw errors. I cleaned the intake solenoid and replaced the bottom exhaust solenoid.
CRC mass air flow cleaner was employed. My approach was straightforward; to begin, I took out the rubber o-rings that were attached to the solenoid’s base because spraying them with cleaning solution would probably shorten their lifespan. After giving the solenoid a short spray to remove any remaining surface oil, I grabbed the solenoid and inserted the small spray stick from the cleaner into the end of the device before flushing it out. seems to force a significant amount of old oil and other debris out of the solenoid body. I continued doing this until the fluid flowing out was spotless.
After turning off the CEL and swapping over at higher RPMs, the car feels fantastic once more.
Last year, I used MAF sensor cleaning to clean my Vanos. I switched them, cleaned my MAF sensor, and cleaned them. For the MAF sensor and Vanos, I utilized CRC. I carried out this maintenance in advance. I’ve never experienced any sort of error.
No specific mileage, merely that when the problem code appears, the majority of men try cleaning before replacing. After cleaning, I was able to go for another 10,000 miles or so before the fault reappeared, at which point I had to replace the bad solenoid. The other one I have is still authentic and error-free.
I had to adjust mine at about 54 kph, however it only occurred once when running the tune. So that I wouldn’t have to disassemble again, I simply changed my. For the last 6,000 kilometers, the cars have been operating without any misfires.
Codes as soon as he changed to the violent song. He doesn’t have much money, so I’ll have to clean his or use my old ones, which is why the cleaning inquiries surfaced.
Yes, cleaning the solenoids has occasionally been successful in providing a lasting fix. In order to replace the solenoid when it malfunctions once more in 3–5 thousand miles, I would advise your friend to start saving $100 on the side.
You all at least have the choice of cleaning or replacing the unit with one of your used ones.

The function of the BMW VANOS solenoid
The Vanos system regulates the intake and exhaust camshaft positions using oil pressure. The mechanism makes use of a gear on the camshaft and a gear on the Vanos actuator. The quantity of oil pressure applied is then controlled by a solenoid, which also regulates the direction—inward or outward—of the cam gear, so regulating the timing of the valves.
Here is a photo showing how the actuator’s gear appears:
How can I tell if the VANOS solenoid is defective?
- loss of torque and horsepower.
- Slow response while applying the gas pedal.
- gradual cold begins
- After accelerating, the auto computer may enter limp mode or experience issues.
- decreased ability to drive.
- loud rattling or harsh idling.
- loitering without purpose.
- low fuel efficiency
Why does a VANOS solenoid malfunction?
Several problems could result in VANOS failure. O-ring failure is the initial problem. Since these rings are composed of rubber, they may naturally degrade with time.
The solenoids, which might develop clogs, are the second most frequent problem. The solenoids won’t function properly if dirt and other materials obstruct them.
A BMW VANOS unit: what is it?
The acronym VANOS stands for a German-made engine part that was created to improve the effectiveness of BMW intake performance. By changing the location of the camshaft and drive gears and opening the intake valves more effectively, this technological advancement streamlines the timing of the engine.
What exactly are BMW VANOS issues?
Fortunately, it is possible to recognize a failing VANOS system using a number of distinct symptoms. A common primary indication of VANOS system failure is the check engine light coming on. Any problems with the VANOS system typically cause the check engine light to illuminate rather rapidly because the system is so essential to the engine’s ability to operate. Naturally, there are a number of additional causes for the check engine light to come on, from a loose gas cap to an engine misfire. Therefore, your best option if the check engine light on your car comes on and you’re not sure why is to take it to a qualified repair right away.
Poor fuel efficiency is another common sign of VANOS system failure, in addition to the check engine light illumination. Your BMW won’t be able to control its fuel usage effectively if the VANOS system malfunctions. As a result, it can begin to use more fuel than usual. Your car may also splutter and accelerate slowly simultaneously as the engine struggles to send the extra gasoline through the exhaust cam. Therefore, there is a good probability that your BMW’s VANOS system has started to malfunction if you detect either of these symptoms, either separately or simultaneously.
What BMW engines are VANOS equipped?
The BMW VANOS engine with a valve timing system is most likely found in any BMW vehicle built in 1993 or later. The effectiveness, power, and efficiency of an engine are determined by valve timing. You must learn how VANOS engines operate, what they are made of, and how to spot failure symptoms if you want to drive your BMW safely and keep it in top shape. These specifics are listed below.
N63 contains how many VANOS solenoids?
This solenoid controls the variable valve timing (VANOS) on the N55/S55 6-cylinder and N63/S63 V8 engines. Each camshaft has a solenoid (two for 6-cylinder engines, four for V8), and if any of them malfunction, the VANOS won’t work or won’t react quickly to signals from the ECU. There aren’t many warning indicators of a VANOS failure, but if you observe a decrease in torque at a given RPM or worse fuel efficiency, these could be signs. The computer and tools needed to test the VANOS system will be available at an experienced shop. For VANOS control or operation, there will typically be a related fault code and check engine light, and in extreme circumstances, there will be reduced power and limp mode.
This solenoid, which may be used with either the intake or exhaust camshaft, is genuine BMW. All cams and banks use the same solenoid on the N55, S55, N63, and S63 engines. Sold each solenode. O-rings are present.

A BMW VANOS code: what is it?
The first system that BMW released was single VANOS. The exhaust camshaft is unaltered in this model, leaving only the intake camshaft’s timing mechanism to be altered. This technology is present on older BMW cars, including those powered by the M50, M52, S52, and M68 V8 engines.
A single VANOS only generates the P1519 error code. This error code means that the VANOS mechanism is jamming and sticking. The symptoms of a single VANOS system failure are poor driveability, reduced horsepower, rough idle, and poor fuel efficiency. In Single VANOS, the electrical connector on the VANOS actuator solenoid may be the source of harsh idling. If the issue persists even after the solenoid has been fixed, the VANOS actuator is likely to have failed and will require maintenance and repair.
How can I tell if my VANOS is malfunctioning?
- loss of power or torque.
- Engine Stuttering @ Low RPM.
- Rusty Idle.
- reduced fuel efficiency
- Cold Start Issues
- Stalling in the Cold.
- producing fault codes.
- Engine Sputters When Accelerating
When should VANOS be replaced?
VANOS System Replacement The seals on your VANOS system should be changed every 50,000 miles, or sooner if you start to experience some of the problems mentioned above. To guarantee optimal engine performance, the complete unit should be replaced or serviced every 70,000 miles.
If my solenoid breaks, can I still drive?
Yes, it is possible to operate a car with a damaged transmission solenoid. However, you should keep in mind that if the issue is not resolved right away, it could turn into an expensive repair.
Additionally, if the solenoid issue is not fixed, the driver will have trouble driving because solenoids govern gear shifting and vehicle acceleration.
What is the lifespan of a VVT solenoid?
It is no accident that your car runs smoothly. The engine needs a lot of different components to work together smoothly for it to operate. The way your automobile idling and operating is greatly influenced by the variable valve timing (VVT) system. This system has a solenoid and a switch that work together to control how much pressure is drawn into the system. Because oil pressure in a car is crucial, there are numerous different components designed to control it. The variable valve timing system’s (VVT) switch keeps track of the amount of oil used and relays this data to the engine computer.
The VVT switch is made to last a lifetime, just like other sensors and switches on your car. The heat from the engine is typically what makes this portion of the car need repairs. Lack of routine oil changes is another common reason for damage to this switch. This switch can become clogged with thick, sludge-filled oil, making it practically difficult for it to function as it should. Maintaining the proper operation of your engine also depends on changing the oil in your car.
The illumination of your Check Engine Light is typically the first sign that this switch is malfunctioning. You must take your car in for a diagnostic examination as soon as this light turns on. The tools required to extract the fault code from your OBD system are available from the mechanic. This will assist you in identifying the problem and arranging for the necessary repairs.
Some of the warning signals that your VVT switch is failing are the ones listed below:
- The engine is making a lot of noise.
- The fuel efficiency is beginning to drop.
- The vehicle won’t idle without stopping.
You won’t be able to get your engine to run as you’ve grown accustomed to it without this switch to help control the flow of oil to the VVT system. To prevent your vehicle from experiencing any additional issues, have a qualified repair replace the worn-out variable valve timing switch.
What is the purpose of VANOS ointment?
Several skin problems are treated with this medicine. The swelling, itching, and redness that can develop in these kinds of situations are diminished with fluocinonide. This drug contains a potent corticosteroid.
What exactly does VANOS mean?
Timing modifications made it simple to manually tune an engine in older vehicles. In those cars, the crankshaft drove the timing chain, which moved the engine cams after spinning the gears in the head.
To increase a car’s performance, it became common to install a different kind of cam. You have to choose between having high-end power for racing and performance and low-end torque for cruising. The timing and operational performance of the engine were fixed. However, modern technologies made it simpler to alter time. Variable valve timing, or VVT, is a feature that many automakers have designed, yet they all provided different explanations for the same problem.
How can a non-turbo engine produce the best power curve while using less fuel and emitting fewer emissions?
An excellent idea that allows for superb engine performance while cruising at a low RPM but also has the ability to spike the RPM is the ability to change an engine’s timing while it is running. VANOS is the abbreviation for BMW’s Variable Nockenwellen Steuerung.
The BMW M50 engines include VANOS integration, which focuses on managing the cam gear, which is mechanically connected to the exhaust gear by a chain. Because VANOS was developed with independent cams and cam gears, each component’s splines were unique. The VANOS gear contains two distinct sets of splines, the inner set of which only drives the cam and the outer set of which drives the cam gear as well. When a helical gear—a twist—is used, the position of the gear between the car’s cam gear and the cam is sometimes only slightly altered.
