Start your car, let it drop to idle, pop the hood and closely listen to the engine on the driver's side. Then closely listen to the sound of the engine on the passenger side. Is it identical?

For me, the passenger side of the block has an extra chut chut chut sound. I was wondering if somethings wrong with one of the plugs or coils or something on that side.

Appreciate it.

Before you take the engine apart :-) check if the belt does the "chut chut" sound. Just spray some water on it, when it's running and listen if the noise changes or goes away.

It's coming from the passenger side of the motor, and its not very noticeable (I have a sensitive ear).

And spraying water on the belt? That could cause slippage.

Water on the belt will not hurt them and will dry up in a matter of minutes. Water enters the bottom of the engine area when driving in the rain. From there, the belts do get wet from time to time.

I don't own a 220 but these cars in general have ALOT of running gear that is a bit noisy when it starts and then goes away when the car is warm, even with cars as young as the ones you guys have there still will be a little wear on teh parts

I finally found time to make a small clip. Turn the volume up and listen closely. The video starts off showing the driver side of the motor (normal sound) and then passenger side. The passenger side has a click click click or something sound.

I don't think its normal.

Man, thanks for speaking up. I thought everyone was trying to ignore my problem, but it was just the video. Video is fixed now.

its kind of hard to judge the sound. i know that most mercedes make some kind of ticking noise, at least the many i have heard but i dont know what everybody else hears. that video makes it kind of hard to tell what im looking for
