sound from under the hood

tommy23g · 03-22-2011, 10:24 PM

Hey guys, i have a winding noise coming from under the hood...it sounds like an RC car when i accelerate...decelerate and at idle..in park etc....pretty much whenever the cars on...when i turn the car off it doesnt stop right away it winds down i thought at first maybe a fan bearing...but its on all the time...even when the fan isnt spinning...then i thought it was a belt but i was pretty sure the belt had more of a squeal or squeaking sound...any suggestions? i can seem to locat the exact location of where the sounds coming from and i havent brought it back to bmw yet but i was hoping that maybe befor i did that i could hear some suggestions and possible come up with a solution...please help lol

At first I was thinking maybe his turbo's were about to crap out on him. But then I noticed he drives an 06 325 so that's not the case...

Otherwise OP, I have no idea

tommy23g · 03-23-2011, 06:33 PM

put a 335i badge on the back roll it to bmw and mabye they will order turbo's and then install turbo's

Video? Does the pitch change with speed?

Or a constant whine?

Maybe it's the water pump? I think that stays on for a bit after shutting off the car.

tommy23g · 03-23-2011, 08:04 PM

when would the warranty on the water pump expire? pitch changes with speed,...getting higher as i accelerate and then lowering when gear changes...so on and so fourth...shit sucks...i might try the 335i badge trick tho lol

hopefully its the water pump, its covered up to 100,000 miles
