While in the parking lot last night -all the windows and the sunroof open- I heard something different coming from the engine of my 03 MCS (28K miles). Here are the detailes:
After the accelerator is pressed and released (as low as 2.0-2.5K rpm), while the engine is going back to idle, there is a "humming tone" coming from the engine. It seems to originate on the passenger side, next to the supercharger. It is NOT the power steering pump whine for sure and it only appears when the engine is going back to idle. It sounds like a "horn" playing 2-3 bass notes. Very weird... I cannot describe it very well, but it is similar to when an air opening is block with something. Weird.
I repeated the same thing clutch repressed; no difference. It is also the same while driving or just stationary.
Any help would be appreciated to diagnose this noise. Anybody else had this?
Sorry for starting with a problem with my first post to the MINI2. I should have posted many happy days with my MINI before.
Thanks!
