A short while back, I had my dealer fit the JCW Air Intake and JCW exhaust. When I got the car back, I immediately noticed that there was an odd, irregular high pitched whistling type noise emanating from the engine compartment when I have the throttle partially depressed at around 2K-3.5K RPM. To my untrained ear, it sounds like a vacuum leak type of sound.

The service dept had a look at it, and is telling me that this noise is "normal for the JCW airbox". I know at least one full JCW that does not make this annoying noise. On top of that, I think it is getting worse. My MCS has the steptronic transmission, and he has about 11K kms on him.

Has anyone else run into this, or have any useful insights?

Hi there,

I also had a similar problem on my MCc (strangely enough after fitting a JCW Sound Kit!!!) it turned out to be the accesory belt that wasn't sitting correctly - however they replaced alot more things before they figured that out!

I have a noise like this with my jcw airbox, that our works GP definitely doesnt have.

I read an interesting post on NAM, where NewYorkCityMini had an identical problem after having the JCW intake fitted.

I've made an appointment at the dealer's next week to try and fit a new throttle body. I'll post on whether or not the "dentist's drill" option is removed from my car.

I had the car in for service this week, and just got it back yesterday. The dealer replaced the throttle body, and the sound is gone! Well, not totally gone, if I listen really hard it is still somewhat there, but it certainly is a lot better than what it was.

Good job MINI Crowfoot!
