Crazy noise while engine is off
What in the world is this noise? It happens shortly after shutting the engine off and will still be going an hour later. Been going on for a month now.

Mine seems to do it every time I drive. One time I washed my car and hadn't started it in 2+ hours and it was still making the noise.

According to the factory description: "The Valvetronic servomotor is activated via pulse-width-modulation. The duty cycle is between 5 and 98 %."
This causes the chirping noise, so it is normal. The only question is if this is normal when the engine is off, and for how long? For such an extended period is suspicious for me. |
