I've just bought a 2001 325i. When I start, I hear a zi zi zi sound, like current flowing. I don't know it's normal or something wrong inside. Hope someone can help me.

Are any lights showing? Check Engine maybe?

I test-drove a ridiculously badly-maintained E46 and it made a short of sound like that, and at ignition it stuttered - but it showed the Check Engine light.

The VANOS pump (top front of the engine) always sounds a little loose at start-up. Have an assistant start your car with the hood up and you leaning over the VANOS, and try to determine if it is from the engine or elsewhere.
