Having problems with your 2002 Audi A4 ?
High Pitched noise\015 There is a high pitched noise coming from the underside of my 2002 Audi A4. This is not coming from the engine compartment. It makes the noise while idling and is not affected when I accelerate. It started this winter during and unusually cold spell...It went away when it warmed up and now its back again, This only happens about 50-60 percent of the time...Any thoughts what might be causing this.\015
I had a high pitch noise, didn't sound like it came from the "underside". Turns out it was one of fans that had little chips in the blades? My Audi dealer replaced it, and it's fine now.

My brand new 2009 Highlander has this high pitch whining noise right from the start. It happens when decelerating, like if you go on a little hilly road, once you get to the peak and then just let gas pedal go so the car just glides down the hill, you will hear this high pitched noise, very high, like airplane landing, but not very loud. What's going on? Took to a dealer, they said it's "normal" operating noise. ????

A high pitch noise that happens after I have driven for 10-15 minutes and then stops when I hit the brakes. Appears to be coming from rear drivers side of car.

My 2004 Chevy Trailblazer is making a bizaar noise when I start it up. It's starts as a high pitch squeal then drops to a lower pitch squeal then ends in kind of a grind. Thought it was a slipping belt but there's only one belt and it's fine. It runs fine and the noise dies away after the engine settles. It only makes the noise on start up. If you cut off the engine before it settles down - the noise continues, so it doesn't stop with the engine. Seems to be coming from inside the engine itself.

2004 ford freestar...I have a VERY high pitch noise coming from the drivers side wheel area. Took it to Midas and they checked everything..my calipers, rotors, bearings, brakes (still had 90%), CV joints...and they couldn't find ANYTHING WRONG!! I used to only hear the noise at high speeds, but now it's happening at lower speeds too. There is no humming, thumping, vibrating, grinding, leaks, lights or smells coming from the van. If i didn't hear that noise, I would neve know there was a problem.
I had this problem and took it to a dealer. There is a service bulletin on this problem... replace the wheel bearings as they are a known problem. Could be a batch production problem. This fixed my problem. ... 2004 Ford Freestar
