Diff noise?
I'm getting a low noise on tight low speed turns. Might be the diff. I noticed on the 1,200 service there was not additive listed for the diff oil. I thought all the MLocks got it. The parts guy said only if they're "noisy".
The noise is hard to describe, but like a low rubbing sound, on both left and right hard turns. You can really hear it in a parking garage with the window down. Anyone?

Haven't heard that yet. Although, I hear many noises in the tranny while driving/shifting. Manual states this is normal because of the way it's connected.

I just had my 1200 service done. I didn't get a chance to drive it for long afterwards. Will look out for this in a controlled situation, but I haven't heard it until now. I do get some kind of a "whine" at around 40 mph from the drivetrain (driving straight), but I don't know where it's coming from exactly. I will check to see if it is still there after the break-in. The service guy is saying M drivetrains make all sorts of noises, and that I should drive it for at least another 1000 miles and then see.
Greg, did you go up to the redline after the break-in? If do, how is it? I'll do that today.

How loud was it? I've experienced a similar sound but it was quite loud - but also I would say a metal rubbing type of sound. It's only happened say three times pulling out a hard left from stand still. Not sure if this is what you're talking about though.

Not very loud at all. Only happens on very turns.

I get the same thing on my E46, had the differential oil changed once or twice, it's still there.

I looked. The line item is "Diff. Oil Add 15".

It's kind of a groaning or rubbing noise on sharp corners. Circling through a parking garage you can really hear it because of the reflectivity of the structure. Happens both turning directions. I don't think it was there when I first got the car.

Diff noise
My SA says he is positive the right fluid was used, and it now comes with the LSD additive in it. He said there is not reason for concern, that it's just the clutches working, but the can put more additive in if it's bothersome. I think I'll wait until next time I have it in for something else, unless it gets worse.

My E46 diff never made these noises, but I heard about a lot that did.

check your stabilizer link bushing if it is already worned-out.. or maybe the thing to do is go to the service center and tell them to check your suspension system in front or your steering components ( control arms , stabilizer links , ball joints) and also tell them that you primally suspected your balljoints and bushing... |

A grinding noise may be heard coming from the differential during slow cornering.
This noise is best heard during tight cornering situations; for example, while parallel parking, driving in a tight circle, etc cause When the rear wheel speed differential varies during tight cornering, a slip stick effect is created on the lining and steel discs incorporated in the differential locking clutch, causing the grinding noise. This noise typically goes away as the locking clutch discs in the differential are broken in. The break-in time varies depending on driving habits; for example, tighter cornering (working the locking clutch) means that it takes less time to break in the locking clutch discs. IF THE TECH CAN VERIFY THAT THIS IS THE NOISE differential oil should be replaced with: 83 22 2 282 583 Special differential oil kit e46 differential = e92 differential with bigger cooling fins. there has been a small percentage of people who have had concerns on slow tight cornering such as parallel parking a groaning type sound is heard from the rear differential. Since this is a same issue known with e46 m3, e60 m5, e63/54 m6 and e90/92 m3. a 'special' differential fluid is used

The final drive ratio is 3.85:1. The 215 gear set (crown wheel diameter 215 mm) has been temperature and noise optimized. A friction-reduced gearing is used. The housing of the final drive has been adapted to accommodate the double-row angular-contact ball bearing. The flanges for the propeller and drive shafts are the same as those used on the E6x M5 and M6." BMW Aftersales Training Thanks for the info on the diff oil. I need to take mine in, as it continues to be noisier than I like. As I said in the OP, it didn't start until the oil was changed at first service.
