Whistling noise fixed
 

It was the intake adjustor. Replaced it. Unplug the electronic connected. Remove the torx bolt....replace with new intake adjustor and rebolt and replug. No more whistle.

Interestingly enough, my low end torque is much more powerful. Hmmm...I guess the intake adjustor makes a difference. It is part of the variable intake system which allows more low end torque with choosing the longer intake pathway @ the lower RPM and more HP @ the higher RPM with shorter pathway (better breathing!) The part cost $150!

See part#7....

Would that be part 7? :dunno:

Yes, part#7...$150 is the intake adjustor. No more high-pitched loud whistling @ idling.

Compared to my original part, it looks like the newer part has been slightly redesigned to prevent leaking of air.

The thing is we get a loud whistling too. A little bit a idle, but as soon as you give throttle you can hear it, it soo loud. I thought it was a consensus that it was a normal sound. :dunno: Which engine do you have?

2001 X5 3.0i.

Hmmm, sound clip? :dunno:

Anyhow, you must have a leak somewhere in the air intake system.

BTW, I never did get a SES light but noticed that the engine throttle response was a little sluggish until I got it fixed (I thought it was due to the 121K miles).

The throttle is extremely sluggish. The dealer told me that it was normal, that it was a software issue. Apparently theres no fix. When I push the pedal, it takes about .5 second or more to respond. :dunno:

Kewl, did you get this sound mostly under load or at all times? I want to be sure i have a problem before going to the dealer. I dont know how to host a sound clip. :dunno:
