BWM Valvetronic Electronic Valve Lift Get the book and DVD here: https://www.createspace.com/4278102 https://www.createspace.com/371201 Valvetronic engines use a combination of hardware and programing to abolish the need for a regular throttle mechanism. Valvetronic varies the lift of the intake valves. Based on signals formerly taken mechanically from the accelerator pedal position sensor, the stepper motor changes the phase of the eccentric cam, modifying the action of the intake valves.This system has a conventional intake cam, but it also uses a secondary eccentric shaft with a series of levers and cam followers, activated by an electronic stepper motor. The Valvetronic engine replaces the function of the throttle body by using infinitely variable intake valve lift. Valvetronic has its own computer housed in a separate unit away from the engine management system, networked through CAN network with the digital engine management system incorporating a 40-megahertz, 32 or 64 bit computer. Valvetronic reduces maintenance costs, lowers exhaust emissions, improves cold start behavior, and provides a smoother running engine. It also does not need specific fuel grades or fuel qualities because of its fine atomization of fuel. Because Valvetronic allows the engine to breathe ...

This is how the electric motor turns the Valvetronic eccentric shaft on a BMW N42 engine. The system has a fault, but I don't know yet what it is. The engine doesn't start with Valvetronic activated. It starts only when I disconnect the eccentric shaft sensor (near the oil cap). The behaviour in the video seems somewhat erratic, but I'm not sure if the fault actually manifests itself here. What do you think?
Valvetronic disabled by disconnecting eccentric shaft sensor. No error on dash but on diagnose we can see valvetronic is put in limp mode home. Done on Malaysian assembled E46 318i 2002 BMW N42

This video shows you how to access the components in the E-Box also known as the electronics box. This area contains the engine computer known as the DME (Digital Motor Electronics Module) as well as important engine fuses. The DME engine computer main relay and injector relay are also in the E-box. This is also the location of the wiper relay which I also demonstrate the location of. I also go over some troubleshooting tips for an odd failure I have seen for the throttle.
BMW VVT Vanos CAM Timing Get the book and DVD here: https://www.createspace.com/4278102 https://www.createspace.com/371201 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 .... Get the whole story right here in this video.

How to identify a failed coil and or a failed spark plug on a BMW E46 and other BMW models
This is a common failure on the M52TU and M54 engine. This would be on any BMW with the above mentioned engines. E46 3 Series. E39 5 Series. X3 E83. X5. The P0344 fault code is for camshaft position sensor A which A is refering to the intake camshaft. My video goes over step by step the process to install a new sensor to fix this common failure of the intake camshaft position sensor.
This is in response to a question on how to remove the VVT or valvetronic motor on a BMW 1 series. This would be similar on any vehicle with the N52 engine. Removing the valvetronic motor on a 1 series with N52 Engine.

An illustration of how the BMW VALVETRONIC system works. The technology removes the need for a standard butterfly valve throttle as the intake valve does this job. The valve can be continuously adjusted between 0.0mm and 9.7mm lift. An electronic stepper motor adjusts the potion of the eccentric shaft depending on the engine operating condition. This allows for fully continuous variable valve control.

Full procedure on how to replace the VANOS solenoids on a BMW 3 Series, 5 Series, 7 Series, X3, X5, X1 or any BMW with the 6 cylinder engine N51 N52 N52K N54. Procedure shown using a BMW X3 with N52. The VANOS solenoids can often cause rough running. This can occur with no fault codes and is usually felt at idle when selecting reverse or drive. They can also set a check engine light with various fault codes. P2A9A Camshaft sensor inlet signal signal invalid for synchronization. P2A98 Crankshaft inlet camshaft correlation value outside reference range. 2A82 Vanos intake stiff jammed mechanically.2A9B Camshaft sensor exhaust signal invalid for syncronization. 2A99 Crankshaft Exhaust camshaft correlation value outside reference range. 2A87 Vanos exhaust stiff jammed mechanically.

BMW Compact losing power up to 2.5k revs? Checked your plugs, your coils, and your MAF sensor already?? Chances are that your CCV (Crank Case Ventilation) valve is either staying full open or full closed! Time for a ccv change out possibly. They are rated to 100,000km or 62,000 before being due for a change out. The symptoms are that the car, when started in the cold winter days, is very rough in idle on start-up and in fact can take two or more attempts to start, after the first attempts stalling. Even when started - for a period of maybe 5 minutes whilst the engine is getting to optimal temperature... the car can be extremely rough in low revs up to 2.5k. Pulling out of junctions is a bitch at low revs - slipping the clutch is the only answer - but causes premature wear on your clutch. On warmer days the start-up issue does not exist for some reason but still power fails beneath 2.5krpm because of the problem... fuel economy whilst in the lower gears and accelerating really does hit the pocket harder than it should - more fuel is being wasted because effectively the engine is misfiring and rinsing the engine. BMW are aware of the issues that are caused by temperature, and the CCV valve. So much so that for colder climates (canada etc) that they created an insulated version of the unit for each of the e46 engines.
The N54 powered BMWs respond amazingly well to tuning, but the increased power has caused some owners to experience misfire issues. Trouble shooting and repairing a BMW can seem like a daunting task with things like an advanced electrical system, specialized tools, and intimidating engine covers. But, diagnosing and repairing the typical misfire is fairly straight forward, and COBB Tuning can show you how!
