Mein Auto: 2008 BMW 528i
Sound on start up.

I Have a 2008 528i with 70k miles. I've notice that when I start the car a click sound comes on. Its hard to explain how it is, but right when I push the start it comes (like a ding). The sound doesn't come on all the time, but it does come on a lot. The car drives perfect no check engine no lights at all. I just want to know what could that sound be or what's causing it.

Thank you!

I've been hearing that click as long as I've owned my car. It's probably an electronic module or some sort. It's normal so don't worry about it.

Source of the noise is throttle actuator.
To see if your car makes that noise, put the key in ignition (turn off radio, fan, to be able to hear that click noise) and turn the key to position 2, you will hear a click noise. That's the sound of throttle actuator doing a self check. Butterfly in the throttlebody turns a little and goes back to it's closed position. Due to age/degradation, 'play' develops in the shaft that connects the butterfly to the actuator; this results in that click noise.

I have verified this by removing the throttlebody from the car while the electrical connector still connected to the actuator and when I turn the key to position 2, I can see the actuator doing the self-check and I hear the noise from that actuator.

Is that a big problem? Why would the trans make that sound?
