Annoying whistling sound at speed


mataku527

Recommended Posts

Since I've had the car, I've had a whistling sound that comes from the driver side.  It is only present when I'm going more than 30mph.  Opening the windows don't make a difference, putting my hand over the roof rail doesn't seem to do anything, I put my hand all over the antennae and it doesn't seem to do anything.  

 

Any thoughts or common causes?

I believe Mr. Mike Self would suggest applying blue masking tape to various potential whistle sound sources (one or two at a time) until the whistle goes away to isolate the sound source. Use the tape to temporarily block air flow over suspect sound sources, such as trim gaps, windshield gasket edges, and so forth. Once you've found the source, making the noise go away is likely to be fairly easy.

just my guess, but since the window position has already been ruled out, that only leaves the front vent window, or rear window, or door seal.  that masking tape idea is a great one

Or the mirror

Or the antenna

Or the door/fender gap

Or the wipers

Or...

As above ^^^   check the front belt line trim.  I had the same problem; sounded like a jet turbine, coming from the windshield, or door.  Felt like it was right next to my head.  Passengers were making jokes about me and my old car!  Put tape all over everything until finally I determined it was due to a gap in the front belt line trim.  Replaced the rusty fastener there, tightened it up, problem solved.

I just had my car painted and all the trim  removed and replaced, somewhat  poorly,  and now I know why it's called the whistling bomb.

 It was definitely making a high-pitched whistle before, but I thought it was coming from my carburetor. 

 I noticed the upper trim  along with the antenna wasn't fastened perfectly  and I plan on giving  The blue tape  treatment  to see if that's the problem

There is a small rubber seal that goes on the top of the door at the front edge that may be missing? If you see the sheet metal edges there then it's not present. I believe that can cause some wind noise.

There is a similar seal for the rear top edge of the door, too.

:(  Looks like it will take some time to figure this out.  I was hoping to make my 2002 my daily driver, but with my usual drive about 5 minutes and hearing how short drives are not good for the car, I only take it out on the weekends.  I'll get working on some of the tips above.  Maybe we should compile a post or list of the most common sites so that it'll be easy to find for the next person.  Gonna start with the beltline trim.  Wish me luck!

    BMW Neue Klasse - a birth of a Sports Sedan

    Unveiling of the Neue Klasse Unveiled in 1961, BMW 1500 sedan was a revolutionary concept at the outset of the '60s. No tail fins or chrome fountains. Instead, what you got was understated and elegant, in a modern sense, exciting to drive as nearly any sports car, and yet still comfortable for four.   The elegant little sedan was an instant sensation. In the 1500, BMW not only found the long-term solution to its dire business straits but, more importantly, created an entirely new

    History of the BMW 2002 and the 02 Series

    In 1966, BMW was practically unknown in the US unless you were a touring motorcycle enthusiast or had seen an Isetta given away on a quiz show.  BMW’s sales in the US that year were just 1253 cars.  Then BMW 1600-2 came to America’s shores, tripling US sales to 4564 the following year, boosted by favorable articles in the Buff Books. Car and Driver called it “the best $2500 sedan anywhere.”  Road & Track’s road test was equally enthusiastic.  Then, BMW took a cue from American manufacturers,

    The BMW 2002 Production Run

    BMW 02 series are like the original Volkswagen Beetles in one way (besides both being German classic cars)—throughout their long production, they all essentially look alike—at least to the uninitiated:  small, boxy, rear-wheel drive, two-door sedan.  Aficionados know better.   Not only were there three other body styles—none, unfortunately, exported to the US—but there were some significant visual and mechanical changes over their eleven-year production run.   I’ve extracted t
