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.

How do you calibrate a BMW Valvetronic?

What are the symptoms of a bad valvetronic?

What can go wrong with Valvetronic systems?

  • Illuminated MIL lamp that may or may not be flashing.
  • Varying degrees of power loss.
  • Rough idling/running at some engine speeds.
  • Excessive fuel consumption.
  • A hard-start or a no-start condition may be present.

Can you unplug eccentric shaft sensor?

From what I’ve researched, unplugging the eccentric shaft sensor disables valvetronic and the valve lift is set to maximum at idle.

What is eccentric shaft sensor on BMW?

The eccentric shaft position sensor is used as a feedback for the Valvetronic eccentric camshaft. The eccentric shaft is actuated by the Valvetronic motor and in return controls variable intake valve lift. The eccentric shaft sensor is mounted to the cylinder head beneath the valve cover.

How do you reprogram a valvetronic motor?

Insert the valvetronic motor and connect its 2 pin plug. Then switch the ignition onto position 2 and within a space of 15 seconds, depress the accelerator pedal down to full throttle 10 times and you will hear the valvetronic motor program itself back to factory spec.

Can you drive with a bad valvetronic motor?

If valvetronic fails, your electric throttle body takes over. Your engine is currently operating as a regular engine with a throttle. It is safe to drive to the mechanic.

What does BMW eccentric shaft sensor do?

What is eccentric shaft actuator?

It is responsible for actuating an eccentric shaft that adjusts intake valve lift. The motor itself is pretty reliable and does not fail too often. It’s basically a camshaft on top of the intake camshaft that controls how far open the valves move during one rotation of the intake camshaft.

Can I unplug eccentric shaft sensor?

What is a Valvetronic motor on a BMW E90?

The Valvetronic motor is used on BMW E90 models with a normally-aspirated engine. It is responsible for actuating an eccentric shaft that adjusts intake valve lift. The motor itself is pretty reliable and does not fail too often. However, you will have to remove it for other engine repairs and the gasket…

How do you calibrate a Valvetronic motor?

Do I need to reset the endpoints on a Valvetronic motor?

Just taking the Valvetronic motor out to replace a gasket and returning it to the valve cover it is not necessary to reset the endpoints. “YOU MUST set the new endpoints using ISTA+”.
