Squealing noise in motion at 2-2.5k rpm. Help!

99 328i automatic, 65k


I have a problem that drives my crazy. Recently I have replaced my waterpump. Everything went well. When in idle, things are perfect. When I drive the car, however, I hear a high pitch squeal coming from the engine area. The problem is that I can ONLY hear this noise when I drive (so I can't troubleshoot it by ear) and it only happens when I depress the accelerator and when the RPM is about 2000-2500. Does not happen when I rev it up while stopped in park or neutral. It sounds totally as if the engine is sucking air thus making the noise - BUT it never did this for the first 65k miles! Does the engine suck more air while in motion? It started only after I replaced the waterpump. Any clues??? Help!

Did you replace your water pump yourself or you paid for that ?
Your car has 65K miles on it, have you ever changed your serpentine main belt? if not, cheked the condition of it ,at this milage they mostly are wear out and have small multiple cracks on the body.It can certenly cause the noise when it slips.Check also proper tension of both belts.

Good luck !

If you have just changed your water pump, did you remove the belt?? I've seen this happen before, when the belt was not removed and it got soaked with coolant....but I do concur that you should inspect/replace the belt.

I think it has something to do with the vacuum/air intake - it does NOT squeal at any rpm while stopped, so that eliminates belt slippage possibility. It only squeals at about 2700rpm when trying to maintain a steady highway speed with the accelerator depressed very slightly. It quits squealing when releasing the gas pedal and coasting.

I just solved this problem on my 2000 328i. It was the second piece of my air intake boot, connected to the ICV. The rubber boot had corroded away and left a 1" air gap... it was enough to generate a SES light as well.

Inspect your air intake system from filter box back to ICV for any cracks or corrosion, you'll likely find something's wrong.

it does sound like hootie is right, since stepping off the gas changes vacuum. i also think that having it in motion may change the relative location of some parts, 'cos the engine torques up on the mounts differently then in idle. samochod pewnie potrzebuje nowej gumy.

I'm with Hootie. BMW Throttle Body air intake boots have had this problem for a long time. My cousins '88 325i had it, and my '99 323i had it. The heat from the engine dries them out over time. It also depends on your climate.
And yes, it WILL cause an SES light.

Hey polish dude, (samochod) if you want to make sure it's not a belt, the only difference on belt load between idle/neutral and driving conditions is power steering pump and A/C compressor demand. Turn the wheel and rev up the motor in the RPM range and turn the steering wheel back and forth. This is probably not the case, but I suppose it's better to be sure.

You also may want to reach down and rotate the compressor hub by hand, just to see if it is difficult to turn at all.

Siezed and/or worn auto. belt tensioners will also cause noises.

I'm more apt to the rotting/split air intake hose myself, but I like to make sure I've covered all the bases.
