VANOS is BMW's answer to variable valve timing. It is a combined hydraulic and mechanical camshaft control mechanism, managed by the car's DME engine management system.
At the lower end of the engine-speed scale, the intake valves are opened later, which improves idling quality and smoothness. At moderate engine speeds, the intake valves open much earlier, which boosts torque and permits exhaust gas re-circulation inside the combustion chambers, reducing fuel consumption and exhaust emissions. Finally, at high engine speeds, intake valve opening is once again delayed, so that full power can be developed. VANOS operates on the intake camshaft in accordance with engine speed and accelerator pedal position.
VANOS significantly enhances emission management, increases output and torque, and offer better fuel economy. The latest version of VANOS is double-VANOS, used, among others, in the new M3.
The VANOS system is based on an adjustment mechanism that can modify the position of the intake camshaft versus the crankshaft. Double-VANOS adds an ....

If you were smart enough to find this explanation of Vanos and if you listened to its entirety,, then hear me out to hopefully avoid costly repairs and damage to your engine. Make sure you change your engine oil more regularly. Only a fool would follow the BMW recommended oil interval. Always ensure you use the best quality engine oil with the correct viscosity. Don't let any "amatures" change your oil and filter . Even if you don't change your own oil , you should always be knowledgeable about what type of oil and quantity of oil your specific BMW takes. This so that you could ensure or prevent mistakes from taking place. The Vanos system is "very complex" and relies on clean and proper oil to operate the variable timing. The oil solenoids have small oil ports and get dirty/plugged up and and will effect the cars performance/operation. These Vanos solenoids get weak with age and don't react as fast and will cause all kinds of issues including engine codes. The vehicle will go into spasms. You should expect to change them before they fail and don't buy crappy "online" no name types from China, always stick to Genuine BMW Solenoids, at least you get a warranty with them. "Don't be cheap".
The crime to the consumer occurs when they take the vehicle to a BMW dealership. BMW dealerships will throw all kinds of parts at it to correct the problem. Note, that not all dealerships are dishonest but some will take advantage of your lack of knowledge. Therefore BMW owner.... "Be Aware of these type of issues". It's very rare Honda and Toyota have problems with the variable timing. That's because they made it simple unlike over engineered German variable timing. I am speaking from experience and my intent is to prevent someone from getting ripped off for thousands of your hard earned dollars.
Great explanation on this subject, thanks for taking the time to post this, Mandy.

What oil should I use 5w40?
Youre a good man sir
U forgot to mention the most important part. A Mann oil filter. Always.
vanos kicked in yo !
I used to have a tuned up e36 325i, I could definitely feel the massive increase in hp when the vanos was fully engaged
Was this in 5th gear?
@@dxrkshvde1877 to all gears over about 4000rpm
@@odysseasa.1313 So is the hp added the already known and stated hp, say for example my e36 320i has 125hp, does the Vanos increase that or it works within that range
That's right. Honda's design is fantastic. In all my years in the field I have yet to see a manufacturer as reliable as Honda. Vtec was also simpler in design with dual valve lift, rather than a more complicated design like BMW valvetronic. But, they're all advancing and I like technology and efficiency. Thanks for posting.
Honda’s are fine but I like to drive something that doesn’t feel like a matchbox car.
Vtrash. Honda's have the personality of a washing machine and look like gargoyles~
the vid is a great service.. it's crazy how the amazing vanos- double vanos.. is now old school tech.. and now it's all about (dual)double vanos fully variable intake with valvetronic.. thank U for the vid!
I honestly think it's a great system. The hellical VANOS gear rarely gets stuck which is why Beemer VANOS tend to be fairly reliable. Yes, the O-rings is it's weak point, but cheap and easy to change if you know what you're doing. A heck of a lot cheaper than other when you need to purchase the whole VVT sprocket.

BMW is one of the most reliable brands out there. It is part of the ultimate Rat-Pack in the automotive world: BMW, Mercedes, Honda and Subaru. It is not opinion, it's what every mechanic knows to be true. Thanks for posting.
ADPTraining Excuse my question, but how come subaru gets a bad rep when it comes to reliability? Do people just mod the wrong parts at the wrong time? Or is maintenance usually neglected? Just curious. Cheers mate.
Thanks so much... and thank you for your profile pic... that's a nice Beemer...

true, it could be valvetronic that makes noise and reaction so slow as well, probably more possible problem!
Let us know and keep us in the loop....
VANOS,in my opinion wasnt perfect on these early beemers ,the sprockets were notorious for failing, but the principal of variable cam timing is excellent, i dont want to compare it with vtec , because it is different ,in that it alters timing rather then lift, but i think honda had a much better system of using valve timing/lift to extract more more from small engines, even if you had to rev the stones off them to access that power.
VANOS chages valve timing (open and closing) not lift. Valvetronic, which I have a video on this channel does increase lift. Thanks for posting.

I've done the chains on broken guides on the m62 v8 .and its a huge job not to mention the procedure if you don't do it right ..the first time .you'll be sorry the next. 9 out of ten times the vanos gears are worn because of the seals in the vanos gears. Its over complicated. That's y so many e38 and e39 bmw r being sold so cheap now .because the owners don't want to spend 5 or 6 thousand on the repair. But the strange thing is in Europe they never have this problem
alex silver thank
You need to retime the CAMs. It takes a specific Vanos Timing Tool set to do the job. Tool sets are anywhere from $350 to $700 and you must follow specific instructions on how to do it. You only need to remove the upper timing covers on both sides, no need to take the entire front off. It takes some know how, but nothing too dramatic. Search the tech-manual and YOU NEED THE TOOL. Spend the $ and do it right. Post back if you need more information. THanks for posting.

The splined shaft of the exhaust camshaft lobe is called the "hydraulic piston set screws" these go into both splined shafts of cam lobes of vanos unit. I need exhaust side camshaft lobe SPLINED SHAFT ONLY...if at all possible thank you.
wiltse0 that's great its not a rare ocurrance that older German cars last a very long time. Intact I recall a friend who owned a vw golf mk2 that had over 400k. My comment was regarding pols that are up to date I was sent talking about 1994 I was talking about 2 decades later then that. Peace and respect!
geil
Read, read, and read but still didn't understand how it tweaked the cam those few degrees to delay valves . Thank you animation ;)
Fuckin love BMW!
What do you use for the audio?
To keep forces in the valve train low, cam profiles move the valves as slowly as possible. This leads to valve overlap where gas can blow freely through the cylinder. Usually you use throttle, blow-off valve, waste gate, design of intake runners, and exhaust headers to control the pressure difference so that the whole exhaust gas does not flow back or you don't blow unburned fuel into the exhaust. With closed throttle this is not possible, and you have to reduce the valve overlap as you close the throttle. Note how this creates a simulated Atkins cycle for the intake valve, but loses efficiency for the exhaust and instead makes the engine loud.
Like with ignition you want to advance the valve timing with increasing RPM.
Repeating the slow-cam-theme: to get a little more RPM, racing engines close their intake too late into the compression stroke, and open their exhaust too early in the work stroke. In racing classes with air-restrictor, in countries without silly tax laws, and in warplanes optimized for the stakeholders, you better just add displacement.
Thanks for posting and taking the time.

No, it's not that simple. It cost more to do the audio capture and editing than the video itself. That's why sound techs and narrators on animated movies make millions. It's about $500 per minute on the cheap side. Glad you like our videos.
Simple solution. Type up a script and do the narration yourself.
Thanks for sharing... For the money it's tough to beat BMW and those makers of the same caliber, except probably Porsche. They last forever if maintained properly, hold their value, exceptional technology, safe and as fast or as slow at the track depending on how much you spend on it. Only the Porsche 911 Turbo 4 outshines all others. Why? For the money, although new in the $100K, no other model will deliver as much on the track, unless you buy a Formula-1 or one of the exotics.
I bout my 05 BMW 352i new. 50,000 miles I still drive it today at 176,000 never had a problem oil change when it needs it and 92 octane for fuel its a 2.5 inline 6 4 door sedan
your lucky
Well, as the VANOS gear moves in and our, while the CAM is turning, it actually advances or retards and valve timing. Vanos is valve timing and Valvetronic is valve lift.
That's whats up..from Ricer to Racer!
Hi...we replace the timing guides on a 01 BMW 740i now I'm getting codes P0011 and P0021 the car runs fine...do you think it will be a bad sensor? If it were a mechanical problem would it be running rough?
230 on my 98 323is..I haven't touched the engine at all, and the only reason I needed a clutch master cylinder is cause the plastic separated from the pedal
I misspelled Vanoss and now i'm here...
Hallo wird nicht einfach nur die Nockenwelle verschoben und nicht das zahnrad weil die Nockenwelle hat ja auch am ende so eine Verzahnung und ich sehe das gerade so dass das Zahnrad am ende stehenbleibt und dann der kolben weiter eingedrückt wird und sich nur die nockenwelle verstellt ist das so richtig ?

This animation only seems to explain how the cam lobe angle is changed when the camshaft isn't rotating. But how is the stationary helical cup mated to the camshaft when it's rotating at engine speed? Does it spin on a bearing once the two are engaged?
I couldn't possible explain the concept if the thing's moving, which is why it looks stationary.
ADPTraining
No problem. I have since removed the Vanos unit from my engine and see that the helical 'cups' are mounted within the camshaft timing gears and always spin at the same speed as the camshafts even when the two are not mated. There's no relative rotation between the two and so both are effectively stationary - as per your animation.
The pistons push on the rotating cups via thrust bearings. Neat!
Thanks for the excellent video :)

I don't know if that adaptation will work. The issue I see is the ECM won't be programmed for the double Vanos. The parts may be the same but what about the software that run the vanos? Anyhow, post back with more. It is interesting.
So the chains probably never need changing? Love it!
lmao, i agree it was an amazing upgrade.
How is it not cost effective? Its the difference of typing and speaking. Only thing that would cost more is a microphone... which nowadays really isnt that expensive. I dont think he means the sound quality, its more the digital accent that is hard to understand at times. Producing these videos with a human voice would be more beneficial for everyone. Nonetheless good video! Thanks
This isn't gmod funny moments
Got another question for you. Am I right in saying that since the double vanos changes its timing variably it is done through pwm? Thanks
Yes, most all manufacturers if not all effect solenoid control by PWM.
ADPTraining
However, the earliest single vanos were not correct? It was a simple I/O, right?

I prefer the VVEL system on my 370Z, as it results in a nearly flat torque curve across the whole rev range.
Agreed, but this is BMWs older system.
@@ADPTraining Thanks, it would be interesting to see a comparison of how well a Nissan VVEL engine compares with a similar displacement BMW Valvetronic engine.
Why they do fail on the S54 so much?
It may be more efficient, but if something tragic went wrong inside the engine, would you really wanna work with the extra hardware that VANOS adds?
Every manufacturer now has a Vanos Like system, so there's no way to escape it. Thanks for sharing.
Yes.
Now go home.
It's not difficult especially on E46 cars. If you can turn a wrench you can work on it!! You say if something goes wrong in the engine..whatever that means? I blew the head gasket on my 04 325Ci because of overheating which was my fault by the way. Except for machining the head I did the job by myself in my driveway. Vanos is just a part like any other. You take it off, do your thing, then put it back! BMW's are very easy to work on. It's a bunch of mythological bullshit that they're overly complicated!!!
You're right, they individual parts them selves are easy to work with, it's how goddamn jam packed it is under the hood that makes it difficult. I still love my E46 though.
Nermin C. You're right about that!! My hands took a beating doing the job! Love my 04 325ci too.. She's absolutely beautiful!!
So my question if your constantly getting Banos codes must mean it's time to change out guides!? Instead of swapping the sensor!?
That may be correct.

I have a Bmw 550i 2015 I was driving I forgot that the car was on manual mode I had the music on so you couldn’t hear the engine that I needed to shift the gear higher since I could hear it I felt in the car that I needed to shift to higher gear but when I did shift to fourth gear the car just lit up like a Christmas tree it shut off on me and I just let it role till a complete stop now the car won’t turn on ... is the engine seized ?
First of all, remove the radio and get rid of it. You didn't blew the engine. All engined are speed rev protected. More than likely you blew a fuse or broke a wire at the engine bay from the vibration. Look into those areas.

Mike Leisz it means you're screwed. Beautiful cars, but expensive to fix.
Could just be the solenoid; swap it with the exhaust solenoid (super easy many vids out there can guide you) and see if the code changes. New solenoid costs ~$150 (always get real bmw/oem parts, not generic crap)

Does anyone think that voice is a computer?
Curious to know as how and where does the system increase valve lift. I thought and I only see Vanos - single or double - that was only designed to change the position of the cam timing either to advanced or to a retarded timing depending on engine load and rpm. However, I don't see how Vanos is also responsible of changing valve lift. Care to explain, please?
ADPTraining
Right, I know that Valvetronic is responsible for variable valve lift. However, in this video at 3:54 on the double vanos it states that the intake valves are extended to 12 degrees with an increase in valve lift by 0.9 mm. So, again how is it possible that vanos also changes the lift when it is valvetronic's responsibility to do that and not the vanos? I think you've added a little misinformation here. Correct me if I'm wrong. Thanks.
You've made a point here. I should have mentioned D-Vanos and Valvatronic. Point taken. Valvatronic is also covered in another video right here in this channel.
ADPTraining
Good to know that I pointed out a little misinformation here and that it shall be taken care of! You may want to make a note of this in the video, I suppose. Otherwise, this can be very misleading to an extent. Thanks.

I agree your right but bmw CBS data and the cars sensors account for all of this, so usually there oil services are pretty correct. the vehicle bases it on time and driving condition and miles so long as you change it regularly you should be good but yes your very right. now the part about bmw dealerships scamming. I don't know about everyone but ive been training to become a BMW tech for 3 months now. they teach us the proper way to diagnose a car. We DO NOT THROW PARTS AT OUR BMW VEHICLES. us BMW techs, at least me take extreme time and care into diagnosing a vehicle. Nor would i ever rip a customer off. there's some extreme knowledge that goes into knowing how to fix a BMW. German engineering is so advanced and always updating. Germans, specifically BMWs are the ones who discovered vanos variable valve timing, and valvetronic variable valve lift. then other companies created there own just like it, BMW techs have very specific repair instruction that we follow for every car. we have websites that fully devote themselves for SIB and common issues to vehicles and what can cause that. So when you get written up for thousands of dollars, remember there's probably a good reason for that, besides you bought a BMW didn't you. there designed for customers not to be able to work on them, so they get fixed/diagnosed correctly
I hear you. You're right on most of your points. Just that there are lots of non dealership BMW Techs that are worth their onions. 👍
So this is basically German V-Tec
VTek is something different.
Vtec yo! nah, just kidding.
