Hi all. I have a 2006 S40 2.4i with the Geartronic transmission with about 57k miles on it.<p>Today on the way home from work a high pitched squeal started coming from the engine compartment. It does not change with RPM or gear selection (or neutral/park) and continues with the a/c on or off as well.<p>It seems to be coming from the upper front passenger side (right) of the engine compartment, but the sound is a bit hard to localize.<p>As it is not RPM dependent I thought it might be the cooling fan bearings, but removing the fan fuse did not stop the sound.<p>The car was ust purchased used from a dealer a week and a half ago, and before I picked it up they replaced the A/C compressor due to the (apparently common) magnetic clutch/heat issue.<p>I have a 3rd party warranty that the dealer threw in, but I'd rather not spend the $100 for the deductible if it's something simple.<p>Any ideas?<p>Thanks!

Re: High pitched squealing (jsalbre)

Sounds like it could be the PCV problem, have you read up on that at all? Do a search here on the forum and you should find some good info. It should be covered under an extended warranty from Volvo. Good luck!

Re: High pitched squealing (carreragt7)

The sticked info post at the top has a couple of threads to reference.<p>Quick test - with the engine running, pull out the dipstick a couple of inches. If the noise stops, it's a broken crankcase breather and very likely a Volvo-covered repair.<p>Tom.

Thanks for the info guys. When I read the intro post a few weeks ago I wasn't having this problem so that part didn't stick in my mind.<p>Sounds like exactly the problem I'm having, though from what I'm reading shouldin't I be having an overpressure? When I pull the dipstick it's sucking air in, not blowing out.<p>Anyway, taking the car into the dealer at unch today, will update with results.

I dunno man. Take a good look under your hood - this happened to my dad's old 960 one night:<p> <IMG SRC="http://lh6.ggpht.com/_NF_7E5UWYkI/SRZB9wZk4pI/AAAAAAAAAfg/AW9X51BSdqU/s800/DSC07476.JPG" BORDER="0">

Well, I suppose that could cause squeaking under the hood. <IMG NAME="icon" SRC="http://www.vwvortex.com/vwbb/biggrin.gif" BORDER="0">

The service advisor told me they don't have an opening to do the work till Monday morning, but he's familiar with the issue and it shouldn't be any problem.<p>He also said he'd hook me up with a loaner car too. Nice, considering I bought it used!

Hey guys, I'm also having a similar problem. But then mine isn't a high squeaking noise. It's more like a low droning noise that's quite annoying to your ears. It doesn't seem like it's affected by RPM or anything. It usually starts when the car is hot and I go over 40 mph. And the sound would die down if I go slower. It's also coming from the lower passenger side of the engine, but I don't know what's down there since our engine bay is so compact. Any suggestions would be greatly appreciated.
