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: 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 ...

Cleaning BMW VANOS Solenoid // SAVED ME $$$
Today on JD CARS I show you how to clean the VANOS solenoid on a BMW E90. I was driving down the street (close to home luckily) when my 328i suddenly misfired in two cylinders and I lost significant power. I babied the car the remaining half a mile home, and it then stalled out in the driveway. I was worried to say the least. After a quick diagnosis I discovered the VANOS intake solenoid was clogged. After spending minimal time cleaning it, the car started right up! This is a very easy repair, and also a good thing to do if your idle is a little rough. THANKS FOR WATCHING AND PLEASE SUBSCRIBE!
