What is the purpose of BMW Valvetronic?
The intake valve timing and duration can be infinitely adjusted using the BMW Valvetronic technology, which combines variable valve lift and variable valve timing. The method obviates the need for a throttle body when used frequently and promises to increase fuel economy and pollutants.
Valvetronic was first used by BMW in 2001 on the 316ti small and has subsequently been incorporated into many of the company’s engines. The N55 engine was the first turbocharged engine to use this technology.
What leads to the failure of a Valvetronic motor?
Between the valve stem and the camshaft, a second set of rocker (intermediate) arms are used in valvetronic engines. An additional, electronically controlled camshaft allows these intermediate arms to revolve around a central axis. The intake valve lift can be changed from fully open to practically closed by this action alone, independent of any movement of the intake camshaft.
In theory, the system is incredibly effective. The problems start later in the life of the vehicle when components deteriorate from improper or delayed maintenance. The BMW N42 Eccentric shaft system is shown in the diagram below since it is by far the most straightforward. The latest BMW V8s use the same method.
Over time, the eccentric shaft and rockers deteriorate, resulting in either poor running or a misfire in the car. These rockers are so perfectly constructed that each one is given a unique number. A replacement shaft is then purchased from BMW using this number.
The main causes of valvetronic failure are frequently improper maintenance or aftermarket oil filters. The aftermarket oil filter on the right side has begun to crumble, as seen in the image above. This results in a decrease in oil pressure and has a significant impact on how quickly the valvetronic system wears down because it isn’t receiving enough oil to keep everything properly lubricated. We specifically utilize genuine BMW oil filters because of this.
Every time we service a Valvetronic engine, we replace the needle bearings (shown), eccentric camshaft, whole set of rockers, oil filter, and oil change with engine oil that is in accordance with the manufacturer’s specifications. Timing chains and intake camshafts may need to be replaced on engines with substantial damage.
These Valvetronic engines are repaired with specialized equipment. At Grosvenor, we make significant investments in tooling to guarantee that every repair we perform is flawless.

Since 1992, BMW has utilized the variable valve timing (VVT) system on a variety of gasoline-powered automobiles. The name is an acronym for variable camshaft timing in German.
The latter “double VANOS” systems are used on both the intake and exhaust camshafts, in contrast to the earlier version, which was retroactively called “single VANOS,” which was only used on the intake camshaft. Since 2001, VANOS and the valvetronic variable valve lift system have frequently been utilized together.
What does the Valvetronic motor do?
Describe Valvetronic. The world’s first engine without a throttle butterfly is the Valvetronic engine. With Valvetronic, the engine can operate without a throttle butterfly because under part load, the cylinder charge is calculated as a function of the valve-opening duration.
How does one set up a Valvetronic?
- Connect the plug in the first step. The plug for the BMW Valvetronic motor has two pins.
- Step 2: Turn on the ignition: Next, you must turn on the ignition and set it in the proper position.
- Step 3: Apply the gas pedal:
How are BMW trouble codes read?
It is simple and quick to read out the error memory using a standalone diagnostic equipment. Just like a pro, you simply insert the connecting cable into the BMW’s OBD2 socket, and the device displays the diagnostic codes. Typically, a diagnostic tool is a suitable weight and useful size.
The drawback in this situation might be the need to first purchase an appropriate diagnostic tool. They are typically available online for less than $100. But not every diagnostic tool is compatible with every BMW.
Be cautious! A product’s low cost does not always imply that it is high quality. particularly for BMW diagnostic equipment. Extremely cheap devices should be handled with extra caution because they can be fake. These frequently have problems or can only be utilized in conjunction with expensive, specialized software that must be bought.
Is driving possible without Valvetronic?
At exceptionally low lift settings, the automobile might not even idle. When the dme notices valvetronic isn’t functioning properly, it disables it with the valves at maximum lift, therefore you should have just unplugged it instead of attempting to actuate it via software. Even with valvetronic off, the vehicle still handles well.
Can a misfire occur in a valvetronic motor?
The key query is whether Valvetronic issues could be the root of this (misfires/shivering) issue. The short answer is no, Valvetronic is not the root of this issue, within the realm of reason.
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.

An example of a Valvetronic problem
The ABS pump keeps your wheels from locking up from too much braking and maintains safe braking pressure. Issues with this crucial component of your F30 BMW can frequently be seen. The fault codes that will appear on your OBD sensor if your ABS/DSC pump is malfunctioning are either “5DF0-Hydraulic unit pump motor” or “5DF1-Hydraulic unit pump motor connector faulty.”
Typical causes and signs A defective valvetronic eccentric shaft sensor, a missing reluctor on the valvetronic eccentric shaft sensor, or improper electrical connections in the eccentric shaft sensor are potential causes of this failure code. An illuminated service engine light would be the obvious warning sign for this error.
How to fix it: Usually, the fix entails a detailed inspection by a knowledgeable mechanic and a service when the affected and damaged parts are changed. The costs for replacement and service are often substantially less through a third-party mechanic than through a dealership facility.
This problem code indicates that the eccentric shaft of your BMW’s valvetronic system is no longer functioning correctly as a result of wear and tear in specific shaft components.
Typical causes and signs The valvetronic eccentric shaft may wear due to wear and tear as well as increased mileage, which will result in the shaft binding. The higher shaft resistance in this instance is what sets off the fault code. Unusual throttle or harsh running would be the obvious warning signs for this, but often no engine light will arise.
How it’s fixed: Our staff at AutoScope will check the wiring, plug connections, vehicle voltage, and limit positions on the eccentric shaft when you bring your BMW in for servicing as a result of this trouble code. Our staff will make a recommendation for the best line of action to get you back on the road following this thorough evaluation.
When your F30 BMW displays this problem code, it means that the valvetronic system is malfunctioning, which affects the vehicle’s typical fuel efficiency and lowered emissions.
Typical causes and signs This fault code can be caused by a broken valvetronic motor, an open or shorted eccentric motor harness, or a bad electrical connection within the motor circuit. A check engine light would be the obvious warning sign for this error.
Bring your car to AutoScope when you observe this error code so we can determine exactly what needs to be fixed on it in relation to your valvetronic eccentric shaft failure.
The phrase “When it Won’t Start, No Fault Code Appears, or Combustion or Injector Codes Appears”
You may have made a quick diagnosis of the problem if your F30 BMW is having trouble starting or occasionally not starting at all, but the results may have revealed one of several fault codes, such as 29CC – Combustion misfire on several cylinders, 30BB – Injector circuit failure 4-6, or DME internal fault.
Common reasons and symptoms include malfunctioning machinery, insufficient maintenance, or excessive strain on the BMW mechanics. In this situation, you might notice the engine light is on, your BMW won’t start, it runs rough, or there is an engine misfire.
In contrast to changing the entire engine management system, replacing the ECU is a frequent and more affordable solution. A skilled and knowledgeable BMW mechanic will be able to choose the best repair strategy for your problem.
What is meant by Valvetronic Exhaust?
1. What is exhaust technology using valvetronics? The valvetronic exhaust systems were first used in 1960 in the exhaust systems of Lamborghini, Ferrari, and other supercars. This technique was a significant advance for the automotive sector, enabling performance, sound loudness, and exhaust gas flow management.
