Are you sure it's the car moaning? Lord know's I'm guilty of moaning when getting into a cold car in the early AM!
Seriously though, I have noticed the same thing with my car. The turbo has <50K miles on it so I think it is fine. Likely something to do with the densitiy of the air and morning dew setting in the turbo FWIW. I can make the moaning go away quickly though. The stereo does the trick every time.
Had the moan from the power steering pump, changed all the fluid, noise gone. You wont believe how dirty the fluid is! And this is one that never gets changed. Just my 2cents.
I am with Prospero as well Volvo gave you a good unit for tunes it always helps.
Interesting input! I'll have to do that to mine this week. BTW, know anyone who has installed an SC-900 in an 850? I may be doing so to mine and wasn't sure about some of the advanced functions working. I don't expect to use the DOlby feature but I was wondering about the information functions ect.
Matt, I have not seen it done, I will check out some info on Mon for you. The functions should work may need the external amp for max thump, and some have dual ant imputs, like I said the 3 stacker system has been some trouble with the cd's stuck, I have taken some apart to retrieve cd's and can not see why the fault occurs, it is clear in other units but not this one.
The Brickboard has an active thread on a very similar issue regarding the "gohstly moan" after starting up. Someone there seems to have traced it to synthetic oils >5w\30 weight and the oil filters ability to pass sufficent quantities on start up.
I've been using Mobil 0W30 for several months now and the car loves it! I still do get the moan sound every now and then though. I have not yet changed my P. Steering fluid so that is next on the list. I'll post results. If you are even the slightest bit concerned about the moan, try the 0W30 at the next oil change. I have noticed a touch more consumption over the 7K miles than with the 10W30, but we are talking ounces if anything. Usually I will be down about 40 oz after collecting all oil from the pan and what pours out of the filter. Add the filter oil into the mix and it is about 6 ounces lost in all. Not too bad for hard driving and 197K miles on the clock.
