If valvetronic fails, your electric throttle body takes over. Your engine is currently operating as a regular engine with a throttle. It is safe to drive to the mechanic. The most common problem is the eccentric shaft sensor.

What does BMW eccentric shaft sensor do?
The eccentric shaft sensor is responsible for controlling valvetronic timing, and has been known to be a common issue. If your car has been experiencing difficult starts, low fuel economy, and overall lack of engine power and performance, this component may be to blame.
What is a Valvetronic eccentric shaft actuator?
The Valvetronic sensor measures the position of the eccentric shaft in the cylinder head which controls the variable valve lift system on the intake side of the engine. The Valvetronic system essentially controls the engine speed by varying the lift of the intake valves.
What are the symptoms of a bad valvetronic?
Common symptoms that you will notice in this case include engine light is on, your BMW won’t start, runs rough, or an engine misfire.
How do I reset my BMW valvetronic?
Insert the valvetronic motor and connect its 2 pin plug. Then switch the ignition onto position 2 and within a space of 15 seconds, depress the accelerator pedal down to full throttle 10 times and you will hear the valvetronic motor program itself back to factory spec.
What causes valvetronic to fail?
Poor servicing or after market oil filters are often the route cause of valvetronic failure. As you can see from the picture above, the after market oil filter on the right hand side has started to collapse.
Can you drive without valvetronic?
You shouldve just unplugged valvetronic instead of trying to actuate it via software… when the dme sees valvetronic not working right it disables it with the valves at maximum lift. the car continues to drive fine with disabled valvetronic.
Can valvetronic cause misfire?
The main question – can the problems with Valvetronic be the cause of such (misfires/shivering) problem? Short answer – within the limits of reason: no, Valvetronic is not the cause of this problem!
Will valvetronic harm my car?
It will not damage anything. By disconnecting the eccentric shaft sensor, the DME will put the valvetronic into emergency running mode. The valves will go to full lift via the DME activating the valvetronic motor and the accelerator will work off the throttle body.
How does BMW valvetronic work?
What is the function of valvetronic motor?
The Valvetronic system is a BMW variable valve lift system which, in combination with variable valve timing, allows infinite adjustment of the intake valve timing and duration. The system claims to improve fuel economy and emissions, and negates the need for a throttle body in regular use.
What is eccentric shaft?
The eccentric shaft is an essential part of the fully variable valve lift control. The valve lift changes continuously from maximum to almost zero by rotating / pivoting the eccentric (shaft) by means of an electric motor.
How do you read a BMW code?
- Standalone diagnostic device. Using a standalone diagnostic device to read out the error memory is easy and fast.
- Laptop with software and OBD cables. You can also read a BMW’s error memory with a laptop.
- Your smartphone and an OBD2 adapter.
What is BMW vanos?
BMW’s VANOS stands for Variable Nockenwellen Steuerung. The VANOS is incorporated in the BMW M50 engines, where they focus on controlling the cam gear, which has a mechanical link to the exhaust gear by a chain.
Does the N55 have valvetronic?
Design. The main differences between the N55 and its N54 predecessor are the use of a single turbocharger, the addition of Valvetronic and the type of fuel injectors.
Does valvetronic exhaust increase performance?
The valvetronic technology allows an exhaust system to control the gas flow, sound frequency, and overall performance. This allows the sports car to have higher torque at low RPMs and even higher horsepower at higher RPMs.
Does damaged exhaust affect car performance?
It is true that if your exhaust pipe has a hole or a leak, your engine performance will be affected. For those driving older vehicles, the problem may not be immediately evident because older cars tend to be slightly noisier and less efficient.
Does changing exhaust affect engine car?
even without silencer the engine will continue to do its work. changing the silencer changes nothing.
Where is Valvetronic located?
Located in Pennsylvania, our team is obsessed with sound. From our marketing department to all of our highly trained engineers, we all have one goal of developing, manufacturing, and delivering the worlds greatest exhaust systems.
What BMW engines have Valvetronic?
A brief overview of Valvetronic technology The redesigned N52 inline six-cylinder engine, which was introduced during 2006, received the second-generation Valvetronic system, while the third, and current iteration of Valvetronic systems is in use on almost all BMW engines across the range of BMW vehicles.
What is the use of eccentric?
It is used most often in steam engines, and used to convert rotary motion into linear reciprocating motion to drive a sliding valve or pump ram. To do so, an eccentric usually has a groove at its circumference closely fitted a circular collar (eccentric strap).
What is the difference between eccentric shaft and crankshaft?
A crankshaft is simply the same as an eccentric, except the eccentric is a much smaller diameter than the shaft itself Crankshaft length mainly depends on the number of cylinders are present in the engine . Firing orders also considered while designing the Crankshaft.
What does eccentric drive mean?
eccentric-and-rod mechanism, arrangement of mechanical parts used to obtain a reciprocating straight-line motion from a rotating shaft; it serves the same purpose as a slider-crank mechanism and is particularly useful when the required stroke of the reciprocating motion is small in comparison with the dimensions of the …
