How do you relearn a valvetronic motor?
Basically you reconnect everything, turn the car ON (don’t start engine), and wait. You should here the car going through the “self test/calibration” on the valvetronic motor. Wait about 30 seconds and turn the car off. Next restart everything should be ready.
What does a valvetronic motor do?
The Valvetronic system is a BMW variable valve lift system which, in combination with variable valve timing, allows infinite adjustment of the intake valve timing and duration. The system claims to improve fuel economy and emissions, and negates the need for a throttle body in regular use.
What is Valvetronic actuator?
The Valvetronic sensor measures the position of the eccentric shaft in the cylinder head which controls the variable valve lift system on the intake side of the engine. The Valvetronic system essentially controls the engine speed by varying the lift of the intake valves.
How does BMW vanos work?
The Vanos system that you likely have in your BMW uses oil pressure to control the position of the intake and exhaust camshafts using a gear on the Vanos actuator and on the camshaft. A long coil of wire wrapped several times, called a solenoid, controls the amount of oil pressure that is applied.

What does Valvetronic mean on a BMW?
This means a BMW with valvetronic effectively negates the need for a throttle body, increases efficiency by minimising pumping losses and improves fuel economy and emissions. This customer’s 135i with the N55 had it’s check engine light come on.
