I was trying to learn more about what this part does and came across this:

So this part is very integral with getting the engine to work, which leads me to two other questions:
1. Can having a faulty Valvetronic Servomotor potentially cause any other issues in the engine by virtue of it not working correctly?
2. Why in the world is opening a door or unlocking it in any way related to a motor that controls the intake valves on your engine? Not sure I understand the connection between the doors and the engine like this. |
Opening the doors wakes up a number of the car's systems. It seems like the issue with the Valvetronic motor is that it turns on and starts doing whatever it's doing when it shouldn't be and that's why we're hearing a ticking when the engine's off. Doesn't seem to have an effect on how the engine operates once it's started up but who can say for sure? My car did it like twice at around 1k-2k miles and then never again.
