Hello. Have a 2007 E350 4MATIC with 223,000km. I find that there is a whining noice when accelerating lightly. Not full throttle and when you decelerate. Usaully when you haven't started the car for a little bit.
It doesn't happen on idle. And only happens once in a while. Not every time. Any ideas?
Low power steering fluid can often be the cause of a whining noise coming from the front of your car, especially if it changes pitch as your engines RPM.

just changed the power steering fluid recently. So that can't be it. I also changed the belt tensioner pulls and another pulls before so.
I just went through a similar thing with my E320 2005. I took belt off and started for 5 seconds and sound went away. I then got a shorter belt and by passed the a/c compressor and started car again and had no whining sound. (A/C compressor)

Have dealer check VMI to see if 2008070002 applies to your VIN and confirm if it was completed. If applicable and not completed, they should diagnose noise if it still exists after pulley replacement for free. If it turns out to be AC compressor see attached bulletin for DIY repair.

hmmmm. I have a bad relationship with my dealer. Lol. I'll see. Could there be any other causes. It doesn't really sound like a pulley. It only happens every once in a while. And it kinda faint now. Ish

I'm not sure if my 04E320 uses an electric fan or a clutch fan. It sounds as if it whines when it warms up especially in summer so I'm thinking clutch fan?

Press the 0 button in the center of your climate control. Does the noise go away? Press it again, does it come back?

It's your tensioner pulley. Sounds like a roaring fan sound goes up and down with rpms. Sounds like the old clutch fans when they engaged on pre 90s cars

well there may be someone else who Googles this problem and finds this thread useful. LIKE I DID. By the way it was my power steering pump not my belt tensioner or idle pulley. Lighten up guys

How is the pulley connected to the shaft? You may be able to dig up something at a salvage yard. There are a ton of 211s on the road and in retirement.
