Do any of you with bluetec engines hear a slight clicking noise when the engine hits a certain rpm (I believe it's just about 1200-1500 or so, but varies depending on circumstances)? My dealer says it's the active engine mounts kicking in, and is normal. I'm not sure if it is the case, as I didn't experience this when the car was new. Anybody out there experiencing the same thing?


I forgot to add- Mine is a 2012 with no airmatic, 19-in wheels.

Thanks,

Mark

 

Admittedly I almost always drive with the windows closed, but I virtually do not hear the engine unless full throttle is used, and even then it is sweet.

If there is clicking in the engine mounts, then perhaps they should be replaced.

 

I just got the vehicle back from the dealer again, and they confirm it is the mounts, that it is normal, and that other vehicles in their inventory have the same behavior. They won't do anything unless the "mothership" tells them otherwise.

The clicking sound is audible with the windows closed; it's more of a solenoid type of click. If the engine is revved slowly, no click is heard.

 

I've the same problem as well on ML350 with Airmatic. clicking noise around 1500rpm
