Hi to all, my 2011 328i with 76K miles, is showing 002A47,002A33,002A32. This has happened like 4 times when I am getting close to a stop light the car turn off just after I have shifted to neutral (Stick shift car) to coast to the light. I have noticed it after I replaced the spark plugs, I know the code is eccentric valve sensor, but could the spark plugs create the code? or just a coincidence , and I need to replace the valve sensor?
Reading codes with laptop and Rheingold ISTA software. Thanks
PS it hasn't happen while driving so far.

Eccentric shaft sensors are a common failure on this engine. Before replacing the sensor, I would recommend removing the valvetronic motor and inspecting the worm gear on the motor and the gear on the eccentric shaft for wear. Do some research on removing the motor first. You can break things if you don't turn the motor the right way before removal.
Post the descriptions of the codes. Not just the codes themselves. You might as well be speaking Latin.
And there is no magic to removing or reinstalling the valvetronic motor. Unbolt it, remove. Install it, bolt it up. Never have I once, ever, done anything other than that. And I'm sure by this point in my career, I've removed/installed hundreds, if not a thousand or more.

Also the Valvetronic has its own power source coming from your battery. It’s the red wire clipped into the second slot on top of your battery and it’s usually a smaller gauge. Check that wire and connections. I replace the whole valve Tronic motor and still got the same codes went back traced it to the power supply and found a bad loose wire and that’s all it was
