engine whistling
 

I notice my 02 3.0 X5 has a strange noise coming in the engine, like whistling sound, specially if you accelerate. Is this normal or time to call the dealer to check this out. Please give me some info for this... Thanks.:)

Search the forum. I think someone answered to this problem. I think he/she found a leaking rubber air intake black tube that was causing the whistling sound.

Yep. That was me who had the whistling sound. My MY05 4.4 had a black condensation drain tube which connected into the vent system and exited down by the transmission. The result: whenever my fan was on at any speed I heard a whistling sound coming out of my vents. That whistling sound was actually the normal whine of my transmission being heard through my vents. If you turn your climate control system fully off and it goes away, then that's what your problem is.

The fix: A new drain hose design avail from your dealer which has a slit for an opening. When water collects at the bottom, the weight of the water opens the slit and it drains out. But no sounds are allowed back up into the black drain tube.

Hope this helps.

I Hate To Sound Like The Dealer But......they All Do That. At Least The 3.0 Its A High Pitched Whine Or Whistle That Sounds Like Its Coming From Under The Vehicle. Only Happenes Under Light To Moderate Acceleration Right? I Think It Might Be The Fuel Pump Or The Transfer Case. In Any Event, All Of The 3.0 Vehicles Ive Driven (loaners, Test Drives, Ect.) Exhibit This Behavior..........fraankie P.

Yes. It's fine. You are just hearing noise that should remain outside the car; not get transmitted inside.

I just went to the dealer today to check it out with the whistling noise, they found out the noise is coming from the water pump, it takes only an hour to replace it, and the whistling noise is gone.

Glad to hear you're all fixed up! :thumbup:

Mine, 2005 4.4i, whistle when I am not pressing the gas and cruising. It is starting to bother me do you think it is the water pump too?

Just check it out with the dealer, u still have warranty anyway.
