BMW Valvetronic Sensor Faults 2a67 and 2a63 Causing Stalling Misfires and Rough Running
This is a problem I have seen on many BMW's. This applies to all vehicles with valvetronic especially on the N46, N51, N52, and N52K engines. In this video I go over what to check on the N46 Engine and what the common cause of this problem is attributed to.
BMW Valvetronic Variable Valve Lift
BWM Valvetronic Electronic Valve Lift
Get the book and DVD here:
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 ...

BMW Valvetronic operation on N42 engine (fault?)
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?
BMW 3 Series E90 Valve Cover And Eccentric Shaft Sensor DIY Fault Code 2a31 2a47
I show you how to remove and replace the valve cover and eccentric shaft
sensor specifically on a BMW 3 Series E90. This video is very comprehensive
and includes some GREAT TIPS AND TRICKS for the valve cover removal and
installation. This BMW would barely run and had a check engine light. The
fault codes where for the eccentric shaft sensor 2A31 DME valvetronic
eccentric shaft sensor guide and 2a47 valvetronic eccentric shaft sensor
plausibility. The sensor was completely failed which led to very poor
running. There was also oil in the sensor pins.
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

How to clear Check Engine Light and Fault Codes BMW
The method of clearing engine light needs to pass inspection. If you have
check engine light turning on after the car runs for several miles. Park to
nearest Inspection station, and after clearing Check Engine Light, bring in
for inspection. This is good only for car manufactured before 1996 BMW. It
