the clutches will wear, but this is what they are intended for. any clutchdisc will wear... slowly...
as long as they scratch, they are still vital ;-)

Had the noise at 30k miles. Went away on its own and hasn't come back. Now at 38k

really?!
bmw doesnt offer spareparts for that unit... they dont even offer the complete vlsd unit... only a new rearend.

you definitely need a special tool to open the vlsd unit. it would really be interesting, where they got the clutches and the tools from as gkn doesnt provide this stuff either.

Am I the only one who had the diff oil changed with the special diff oil, and the noise remains?

It can take quite a few miles for the modified diff oil to work its way between the clutch plates in the diff....making tight figure of 8 turns in a parking lot can speed up the process.
For future searches on this issue:
My car has made a rubbing noise from the diff when cold on slow speed RH turns since new but I refused the offer from my SA of having the modifed oil...45K miles later it still does makes the same noise with no ill effect I can discern. On the plus side the diff locks up perfectly - smooth power slides in the wet and dry are super easy to perform.
AIUI the factory diff oil fill can be one of several diff oils and it does occur to me that that perhaps one of the factory fill oils is less able that others which would account for the rather random occurence of the the problem only affecting some cars.
The Castrol SAF-J diff oil has been around for a long time and is very popular with manufacturers so I'm wondering if the affected cars got some other inferior oil?

do the turns that is stated by the SIB when the modifier fluid is changed.

Also, I would check the receipt and look for the part number that's unqiue to the additive just to make sure they used that fluid.

I did the turns as stated in the SIB, I checked the part # with the one on the receipt, they match up. So weird. The only thing I can think of is an independent shop did the diff oil change, and not the dealer. I may take it to the dealer and have them change it once and for all.

I also hear the scraping noise when driving in a straight line, downshifting, and engaging the clutch fast. At the point of engagement (clutch pedal released), it emits that scraping sound. This scraping sound is also present when in gear, under engine braking, usually more audible when the car's not warmed up yet. Same scraping noise can be heard when engaging clutch in reverse, in a straight line, even when car is completely warmed up.

I'm suspecting there is something more going on here than a noisy differential.

The diff oil with extra friction modifier will only "fix" the rubbing noise heard when making relatively tight slow turns usually when cold.
Your noise sounds more clutch/MT related....can you make a recording of it?

Just heard this noise for the first time a few days ago n have duplicated the noise a few times since. I guess im gonna have to call the dealer. Is this a recall (free service) or is it something I will have to pay for?

Not a recall. FIY, this is an issue that was pretty common with the E46 as well. Usually when people switched to a new diff fluid and had noise, the issue almost always went away when going back to OEM fluid with friction modifier.

Mine will go in on Thursday for this issue. My sound is a low whoooo whoooo. Is that what people call grinding noise?
Knowing how clueless my dealer usually is, I need as much information to take with me as possible.....
