Sounds normal,probably normal operation of the cats.

m3cragg · 08-27-2013, 12:11 PM

check in your air intake and airbox something might be stuck in there
sounds fairly normal to me

flaouer · 08-27-2013, 12:48 PM

even this kind of bird whistle? hear carefuly at 1 second on the first video...

maybe i'm paranoiac, but some M3 owners told me they havent this sound.

my second guess would be idler pullies and drive belts, but usually when those go bad, you would hear it all the time, even when idling without reving.

ive checked any leak on exhaust/ lambdas under the car and nothing , but i couldnt check on collector

as u say its only when i accelerate under 2K rpm, above this the noise disappears...

just came back from bmw, they told me it's "typical" of ///M

but this bmw dealer never saw any bmw m3 e9X... :/

positiveions · 08-28-2013, 11:39 AM

Do you have an aftermarket filter?

bkrM3 · 08-28-2013, 01:18 PM

That sound at 0-2 seconds in the first video is a distinct whistle. Don't hear it as much in the other videos, which sound pretty normal to me.

I've never heard a whistle like that and I drive 99% of the time with my windows down. My car is an 09 (which has a slightly different air filter than the newer models if I recall correctly - or there's some difference in the air box, I dunno) and I did not hear that noise with either the OEM filter or the AA green filter.

Swapping the filter to troubleshoot would be the first thing I'd do. Sounds like intake noise.

MRV99 · 08-28-2013, 02:10 PM

I can hear that whistle. My wife had a E53 4.4 X5 and I had a similar whistle. It was a small crack in one of the rubber boots on the intake track. It was on the underside of the part and you could not see it. I hope this may help.

It sounds like an aftermarket filter. I thought mine sounded a little weird at first after installing the active filter

it's probably the filter.

flaouer · 08-31-2013, 04:04 PM

i've already tried to put the oem filter for 2Minutes, and still have the noise...

Cool Steel · 08-31-2013, 04:45 PM

Its the supercharger you wife secretly installed for your birthday...
I'll second or third the aftermarket filter that that reduced your HP...
