Question about 2003 BMW 325

1 Answer

Hi, I have a Canadian version of BMW 325i 2003 automatic with 132000kms or 82000 miles. It makes a high pitch whistle at acceleration and disappears when past a certain rpm but comes back when cruising at a constant speed. Question; what it could be and is it a common occurrence in these engine types? Thank you

My 2007 Land Rover Freelander makes a whistling sound when vehicle is idling. Sound goes away when accelerating or applying petrol?


it may be a turbocharger if so equipted, lots of turbocharged cars whistle as the unit gets older..only other thing I can think of is something with the exhaust system.. get it looked at by putting the car up on a lift and inspecting it..now some cars also whistle thru the radio ..this is called alternator whine and is usually correected by a filter in the power line of the radio...good luck

2003 PT Cruiser turbo. Has just 67k miles on it. Just began making a low pitched loud whistle sound on acceleration or load/uphill. Gets louder with greater acceleration/load, no decrease in power.


I took my car to Keller's Auto Repair in Gettysburg PA, He specializes in Chryslers. I have 04 Cruiser with 2.4 Turbo that had the same whistle noise, and check engine light on. He found code P0301. The noise was caused by the #1 Cylinder injector O ring. Check them out on facebook. They will help you.

My 2003 Ford Explorer has a high pitched whistle around 2000 RMPs. If I accelerate or decelerate the whistle stops. I've replaced the idle aircontrol valve, as I read this could be a possible solution to...


you may have a tensioner or idler pulley starting to go bad. They make a high pitched whistle when the bearings are on thier way.

Simply have someone slowly bring it up to 2000 rpm and listen with the end of a wooden broom handle touching the center bolt on each. Be careful not to get caught.

If you're not used to this you may be able to hear it whithout use of the "hearing aid"

Your drive belt may simply need dressing. You can buy this at almost any auto parts store for about 4 bucks. (dont use anthing else as you will cause the belt to stretch creating more issues)
