High Pitched Whining (996)
Discussion
No .. Not a joke .
I've noticed this getting increasingly louder over the last few months .. It appears to be a transmission related noise as it disappears once slowing to lower speeds (say 10mph and slower). It's most noticeable when decelerating in or out of gear,is louder once the engine warms up and is hard to pinpoint the source of the noise , but at a guess its coming from the drive shaft area.
I pointed the noise out when last at my OPC and their response (after a drive in the car) was 'older 996's make various noises , don't worry bout it.'
SO ...... I don't worry about it , and if something gives I'm assuming (naively) that the warranty will look after it. In the meantime , curiosity leads me to post this thread......
Anyone come across similar noises like this before??
Meant to say , it's a C2 , so it's not the usual C4 drive train suspect.
(it's not coming from my wife as it also occurs when driving alone...)

I hate to tell you this.
Mine started doing this about a month ago. Got the OPC to check it out at the service last week. Gearbox bearings failed.....new gearbox needed.
Please tell me you've got a warranty......please......
ETA: just seen that you have. They told me it was a £8k+ job to rectify....all taken care of by the extended warranty.

Ta C2 .. I'm not remotely surprised by this , it's screaming 'transmission/ gearbox' at me .. And I'm screaming 'warranty' back at it!!
I'm curious to know if your 'box went all of a sudden , or was it still working for you when you had it brought in?
... I don't want to be left stranded some morning on my way into work...
TGFW.

Had a wheel bearing go and the symptoms were similar, fixed for nothing under warranty, but
even without, this is a cheap one, hopefully that's what it is.
It may sound louder under deceleration simply because of the engine noise decrease and the relative sound of the damaged bearing appears louder.
More worried about the fact that it is louder when the engine is warm though......
Can you put it on a bridge, or stands and manually rotate each wheel ? You should be able to ear/feel the difference if one wheel bearing is on its last leg....

Nah I'm still driving it and it's fine. The OPC reckon it'll take about a month to get a new 'box sourced from Germany and just to drive it in the meantime.
Your's sounds more 'gone' than mine however, as the whining comes and goes and you don't really notice it much. I haven't noticed any difference in the feel of the 'box either. Which is kind.

Gulliver,
Was that the OPC warranty?? I rang OPC and they said wheel bearings not covered under extended warranty. Were you lucky or am I just getting an unhelpful OPC. BTW what OPC did you use??

My wheel bearing is getting replaced by an indie tomorrow, I too was told it is not covered under warranty and i trust the souce, so looks like you were lucky Gulliver!
I had the same whining noise at speed, thought it was transmision, but when i had an oil sensor repaired OPC brought it up after a test drive.

I confirm that my wheel ball bearing was replaced under OPC warranty, this was the original OPC warranty on a less than 2 years old Boxster at the time.
Not sure if this is covered under Extended Warranty, but one would hardly call a wheel bearing a consumable, bearing failure should be covered.

I only get the noise when decelerating , either in or out of gear , I don't think it's a wheel bearing, I'd be hearing it all the time , surely?
I was messing with it today and the noise is more pronounced if I put longitudinal (for want of a better word) pressure on the gear lever whilst in gear, so it really is pointing that direction.....
Would any of you have any idea if it'll go suddenly or just get louder ?? .. All gear changes are smooth (2nd of course is a little stiffer than the rest)

If you can effect it by moving the gear lever it's not external to the box. If it's on the overrun then it could be excessive backlash on the gears or as has been mentioned a bearing.
Is it in all gears or one gear in particular. Is it like the diff whine you used to get in old Fords?

It's in all the gears on the overrun most especially , and yes , now that you come to say it , I'm reminded nostalgically of the diff whine while the short pants legs are getting roasted off me on the plastic back seats of my dad's cortina!!!!!
(Just how old are you Blairie ole buddy!!!!

The way you describe it it sounds like excessive backlash in the diff or slight wear on the trailing faces of the bevel gears. Pushing on the gear lever *could* be altering the clearance on the gears making it more/less pronounced. I've never taken a Porsche box apart and I'm only going on a schematic here but if it bothers you I would get on to the warranty people. How many miles on the box?

My noise stops when the clutch is in on mine- so it sounds like it's definitely a different problem.

I'm 85 miles shy of 50k 
(It's a big milestone for me so be gentle!!)
I would have presumed more mileage before I'd see any gearbox problems but there you go ..
I'm not really worried about it as Porsche will (hopefully) cover it, I'm more curious to know what might happen next , will it involve me sitting at the side of the road going 'Why didn't I get this sorted earlier'
The reason for holding back on getting it looked at is that it'll take a day to get up and back from Belfast and I just don't have that to give for the next few weeks.
... So .... Can I get away with it for the foreseeable??????
