Valvetronic mufflers are designed to be used throughout the exhaust system and offer a safer experience. Additionally, the utilization of vacuum exhaust valves ensures that this kit will last and you will not have problems with electronic component failure like most of the competition.

Can Valvetronic cause misfire?
For a warm engine, the threshold for misfires is by Lambda around 1.4 .. 1.5. So – unless the wear of the Valvetronic is not so significant, that the air fulfillment of the cylinder is for 50 .. 60% less than optimal – Valvetronic IS NOT the cause of 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 failure?
Typical causes could include poor electrical connections, a damaged or defective actuator motor, low system voltages, or a binding/sticking eccentric shaft. The presence of this code will typically cause the Valvetronic system to be deactivated, and in some cases, a limp mode to be initiated.
What does Valvetronic 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 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.
Can you unplug eccentric shaft sensor?
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. In layman’s terms it will run like a conventional non valvetronic engine.
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.
How much does it cost to fix a valvetronic motor?
Repair cost is around $3,400.
What does valvetronic motor do?
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 does a BMW eccentric shaft do?
This gives faster and more precise throttle response. What controls valve lift is an electric motor and an eccentric shaft that adjusts the valve lift. The eccentric shaft sensor measures the rotation of the eccentric shaft that translates into how much valve lift there is. The sensor itself is a HALL effect sensor.
How does BMW eccentric shaft work?
What is valvetronic exhaust?
Valvetronic Technology Fi EXHAUST. 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.
What is BMW VVTI?
Variable valve timing is a regular feature of modern motors. Before the invention of this technology, valve timing was restricted to the type of camshaft used. In short, VVT controls the timing of the intake and exhaust valves opening and closing. Valve timing impacts performance, emissions, and fuel economy.
Can you drive with a bad valvetronic motor?
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.
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.
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.
Is Valvetronic exhaust good for engine?
Advantages and Benefits. Fuel economy increased Valvetronic offers the customer direct, immediate benefits, with fuel consumption and exhaust emissions decreasing, but dynamic performance and the spontaneous response of the engine improving accordingly.
Are Valvetronic exhausts good?
I’d definitely recommend grabbing this exhaust. Bryon Solomont recommends Valvetronic Designs. Very good customer support along with good delivery times too, the sound is amazing, extremely easy install and never an issue with fitting, highly recommended.
What happens when VANOS fails?
If the VANOS system fails, your BMW will be unable to properly regulate its fuel usage. As such, it may start to burn through more fuel than normal. Simultaneously, your vehicle may also sputter and accelerate sluggishly, as its engine will struggle to push out the increased amounts of fuel through the exhaust cam.
What RPM does VANOS kick?
3500 RPM on E36 or very close to that number.
What RPM does VANOS engage?
From idle to redline. 0-8K rpm.
How do I know if I have a N54 or N55?
Probably the best way to tell without looking under the hood… is IF it has a DCT it is an N55. IF its an auto it is an N54. IF its a 6MT… you’ll have to look under the hood.
When did BMW switch from N54 to N55?
BMW’s N55 engine began production in 2009 and started replacing the N54 in 2010. However, most applications built in 2010 still carried the twin turbo N54. The N55 officially replaced the N54 in 2011 (with the exception of the 1M and Z4 35i).
