Whistle
 

Hey guys! When accerlating, I hear a whistling noise from the left front wheel or is it the wheel? Anyone heard this?:stickpoke

p.s., Anyone had the engine flushed? If so, who and what brand?

For the whistling noise its most likely your "elbow intake tube". It happens allot. If it is you have two options you can have the elbow replace(easy fix just a b*tch to get to) or you can get a special tape to seal the leak.

Just replaced the elbow part was 16 bucks and took less than an hr to change. had the same whistle your talking about and now gone.

Thanks to Everyone for your responses. I have ordered the part to be installed ASAP!

ok, I had the $13.40 part installed for around $80. Yippee! Another question. When your start you bimmer -- does it sound like a volkswagen with a faint rattle from the rear/muffler/exhaust. After about two minutes it quiets? This is my first bought used so I am still learning the vehicle -- what to expect.

mine rattles a bit also. but i think its just the way it is.

ok, thanks -- glad to hear. One more question, how's your gas mileage? I was thinking to change out the Induction Throttle Actuator also. I just change the elbow intake hose and the whistle is gone, but it seems a little slow. No engine indicators anymore and it passed emissions test yesterday. Your views?

as far as mpg i get about 16, but have been doing highway trips lately. should be somewhere around 14.5/15. strange to me i used to get 13mpg on my 02 530i sport

Seems to me that I am not getting good mileage. I may be paranoid as I am a runner. I went through emissions and should have detected a lean code as before the elbow replacement and if the actuator is bad I should still have a code pending. It's up in the air whether I will replace it. Had yours replaced yet?

i haven't gotten to replacing anything under the hood except for the valve gasket. Everything seems fresh probably previous owner took care of that for me, and i'm not a big fan of replacing stuff before they break, however i am one of those that will be annoyed if something doesn't feel right. could be paranoia!?!!?!
