What does the BMW Valvetronic do?
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.
Is Valvetronic a feature of the BMW N54?
Both engines have direct injection, double-VANOS (variable valve timing), an open-deck engine block, and an electric water pump. The N54 was produced alongside the normally aspirated BMW N53 engine. The N54’s 2,979 cc (181.8 cu in) engine displacement, lack of valvetronic, and magnesium alloy engine block are all due to the fact that it is based on the earlier BMW M54 engine (variable valve lift).
The N54 differs significantly from BMW’s prior straight-six engines in that it uses turbocharging. To reduce turbo lag, the N54 utilizes two tiny low-pressure turbochargers. Although the term “TwinPower Turbo” has now come to refer to engines with a single twin-scroll turbocharger, BMW advertised the twin-turbo as such. An air-to-air intercooler and 8 psi (0.55 bar) boost pressure are employed. The N54 produces an extra 34 kW (45 bhp) and 108 Nm in comparison to the normally aspirated BMW N52, which it succeeded as BMW’s highest performance six-cylinder engine (80 lbft).
Piezo injectors are used in the direct injection system of the N54, which BMW refers to as “High Precision Injection.” Because piezo injectors are more expensive and don’t perform as well as solenoid-type injectors in achieving the “lean burn” effect, the N55 is its replacement.

What does a BMW eccentric shaft sensor do?
The eccentric camshaft of the Valvetronic valve is fed back using the eccentric shaft position sensor. The Valvetronic motor activates the eccentric shaft, which in turn regulates the variable intake valve lift. Under the valve cover on the cylinder head is where the eccentric shaft sensor is located.
Driving without valvetronic is possible.
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.
Valvetronic actuator: what is it?
To help the vehicle achieve the highest potential performance and fuel efficiency, the Valvetronic actuator regulates an eccentric shaft that determines intake valve lift. Sadly, these motors are susceptible to failure with time, which can cause a loss of power and the appearance of the “check engine” light. We are able to provide this new actuator from VDO, a significant savings over what a BMW shop would charge.
After the actuator has been changed, the Valvetronic system’s “limit stops” frequently need to be re-calibrated using a unique BMW diagnostic tool. Before installation, we advise communicating with a qualified BMW mechanic.
This valvetronic actuator was ordered by me two days before Christmas, and it was delivered within a day. The solution, which resolved the issue resulting in a persistent engine light, is of original OEM quality.
Valvetronic exhaust: what is it?
An exhaust system’s ability to regulate gas flow, sound frequency, and overall performance is made possible by valvetronic technology. As a result, the sports car may produce more horsepower at higher RPMs and more torque at lower RPMs. Generally speaking, drive modes, OEM buttons, remote controls, or remote controls can all be used to engage the exhaust valves. Additionally, Fi EXHAUST has created the “Fi EXHAUST Pro” mobile app for smartphones running the Google Android and Apple iOS operating systems. The App is simple to install and gives additional customization choices, including setting up Auto Mode based on RPM/Speed/Turbo, default valve mode on engine start-up, and many more features to let a driver get the most enjoyment out of their vehicle.
Modern technology has always been important to Fi EXHAUST, and we are constantly looking for new ways to incorporate it into our products. That is why “Intelligent” is highlighted in both our full and condensed brand names to direct our future work and keep pushing the boundaries of what is possible. This also includes creating software, such as a mobile app, that work with the hardware and enhance how well our products are used.
This ongoing development and incorporation of the most recent technology has distinguished us from the competition and given drivers access to an intelligent exhaust system in addition to a distinctive sound note. Drivers can fiddle with custom features using our clever control box and the Fi Pro App. Examples include customizing what physical buttons on a new 2-button form remote control do, or automatically detecting and clearing a Check Engine Light (CEL) associated with the catalytic converter on specific car models.
Why does Valvetronic malfunction?
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 signs might point to a failing Valvetronic?
The good news is that the Valvetronic system is fairly resilient in that it rarely, if ever, fails catastrophically given the relative mechanical simplicity of the system. The eccentric shaft’s movement or rotation is prone to problems, and this is perhaps the most frequent difficulty with Valvetronic systems.
Whatever the reason of a binding or sticking eccentric shaft, the typical symptoms could include one or more of the following. In the majority of situations, the repair is difficult, time-consuming, and expensive.
- MIL lamp that is on and possibly flashing.
- different levels of electricity loss
- rough idling or running while using certain engine speeds
- excessive use of fuel
- There could be a no-start or hard-start condition.
- Since mechanical noise(s) may or may not be present, its absence shouldn’t be interpreted as a lack of proof that a mechanical issue might be there.
NOTE: While electrical difficulties like anomalous voltages, currents, and/or resistances might interfere with the operation of Valvetronic systems, failures of actuator motors and programming faults that cannot be fixed by software updates or patches are rather uncommon. Eccentric shaft position sensor failures or flaws are, in fact, the most frequent electrical issue with Valvetronic systems.
The DME will adjust the intake valve lift to around a mid-range opening when the engine is switched off to allow for more air and fuel to enter the cylinders during cold starts. This final point is particularly crucial to remember. As a result, if the eccentric shaft position sensor is faulty or not functioning properly, the DME may fail to set the proper valve lift distance at shut down, which will almost always result in cold start troubles.
Nevertheless, the lack of technical knowledge regarding the meaning of the various trouble codes is the true challenge with diagnosing Valvetronic problems. For instance, if you are using a scan tool that is compatible with BMWs, you might uncover one or more fault codes that are unique to BMWs, such as 2A59, 2A5F, and 2A63, among many others. Even though these codes are specific to Valvetronic problems, the lack of definitions to guide you in the proper diagnostic direction renders them practically useless. Additionally, even from official BMW sources, it can be challenging to find relevant trouble code definitions and service/repair information, which begs the question:
Does the exhaust from valvetronic affect mileage?
Fuel efficiency improved By reducing fuel consumption and exhaust pollutants while enhancing dynamic performance and the engine’s spontaneous reaction, Valvetronic provides the consumer with instant, tangible benefits. Additionally, because the valves only minimally move during a carefully orchestrated procedure, an even higher quality of running smoothness is met.
This idea of throttle-free engine load management ensures an increase in fuel efficiency of at least 10% under normal driving conditions experienced by a customer and 10% or more in the EU cycle. The main tenet is that the driver should operate the vehicle at lower loads and engine speeds to maximize fuel economy relative to other concepts. The consumption figures the driver may obtain in this fashion are comparable to the fuel economy that, until recently, only a diesel engine could provide.
The 316ti now accelerates well over a second faster to 100 km/h than its predecessor, reaching this significant record from a standstill in 10.9 seconds, demonstrating how much more dynamic the new four-cylinder is than its predecessor. The 316ti’s highest speed has increased to 201 km/h or 125 mph, which is 11 km/h quicker than the top speed of the previous model. The standing-start kilometer now takes 31.6 seconds, which is 1.8 seconds faster than previously.
