500E zoom
 

hi,

When I'm driving around +- 1500rpm I hear a zooming noise in the engine bay!

If I go faster or slower It disappears.

It doesn't matter in what gear the car is.

Does anybody know what my problem is?????????

I put the A/C off and on this doesn't make any differences to.

I hope somebody can help me:)

Thanks .

That is most likely the engine fan turning on and off. The main fan is controlled by a hydraulic clutch that works more frequently in the hot weather.

BENZMAC,

thanks for the reply!

So I think its broke , its really anoying when you are cruising and the engine revs around 1500RPM.
