my new Engine sound not even at idle

aladdinAndMagicBmw · 10-26-2010, 03:16 PM

I got a new 328xi almost a month. At the first few days I didn't care about not-even engine sound, because I was so impressed by its driving fun.

When I pick up the car, the engine sound was not even at idle when I started car. Irregularly, there was very little tremble, like this ____/\_____/\___/\________________/\__

The dealer said it's okay and it will disappear.

But still I hear and feel the irregular engine sound. It's very little but noticeable. Maybe I am too sensitive?!

Will it disappear if I drive more?,

or is it normal BMW engine sound?

Are you talking about at idle? Does the change in tone correspond with a change in RPM? If so, is the range large (ie >150-200rpm)?

Mine on a cold start sometimes has a RPM pop of about 500 up and down about 5-6 times.

Given OP's location and large oriental population in said location, in conjunction with his syntax, I would wager he is Asian

Probably like a stumbling at idle. That would make me nervous too, but it's probably nothing and you're under warranty.

one of your valves has a murmur. once it seats, it'll go away.
