I meant to ask you on Friday if you'd had any DU replacements considering you're still on your original A pack.

Well, the DU is separate from the battery pack and is not replaced as part of this work. Aside from somewhat slower Supercharging, my A-pack seems to be doing okay. I did have the main contactors in the pack fail, but all of this is separate from the DU.

It will likely live again. Also could have been the gearbox or inverter, unless you were told specifically that it was the motor.
Service center said they were replacing the entire drive unit. Not sure if that's with a new one or a refurb one, but certainly not my original one.

Mine was replaced (again) yesterday. Part number is 1002633-00-Q. No indication on the Service Order, but the Service Manager said in passing that it was a "remanufactured" unit. The annoying "clunk" is gone and the incessant "angry mosquito" buzzing is also gone!
It's only been 1 day, but all the whining and high pitched squeals I heard from my original drive unit at various speeds are now gone with the new one... Crossing my fingers.

Has anyone with a "Q" DU revision experienced any issues yet? I'm under the impression that there's at least one case where the milling came back. I'm due for my second annual maintenance and I'd like to get everything done at once, but I'm hesitant if they're still working on updated versions.

Just learned that my S received another drive unit. This will be its fourth. Car has 41K mi on it.
The previous drive unit lasted um . . . 7 months. All I had reported was that I noticed the very beginnings of the milling/cicada sound. I figured it'd take 6 months to get real loud and obnoxious. Well, some service tech noticed the faint sound too, and they had a drive unit refurb lying around, so they decided to proactively swap the old one out.
Also getting a new brake vacuum pump, and new heating system (the latter being the main reason the ranger came to tow the car away).

I just received a new DU for the milling noise on 3/2/16 with 26,000 miles on the car. I think it's a Q? The invoice says ASY,P-TRAIN,MECH,COMPLETE,RC (10026xx-00-Q).
Anyways, my car has never been more quiet. I've been driving around the past 2 days without any music, and I'm blown away how silent the car is. I'm pretty sure it's quieter than when I first took delivery. Can barely hear a whine at acceleration! It might just be me, but it feels like it drives different as well. Thanks Tesla! Never been happier!

Spoke to my service advisor and a technician. Both told me that they have the milling issue sorted out. Hopefully that is the case. But you have an 8 year DU warranty anyways so if it comes back, you can just get it replaced with a newer revision DU down the road.

Thanks for posting the positive too. I think too many folks here are only reading about the "concerns" and there are not enough praises.
Since this thread is still active...
Even though the post below is old, and you used the words design flaw, I figured I'd point to another post in another thread... (You're not the only one to refer to repeated DU problems (mainly noise) as a design flaw...)

(emphasis added is mine)
I disagree that there is an absence of a "fundamental design issue" and argued my case starting at Review calls Tesla's Motor subpar - Page 5. About the only way someone can make that statement is if they had knowledge of every single DU that came back and the root cause of each problem. Even w/that, design flaws can still be discovered later.

32k kilometres on a May 2015 delivery S85 and I have the milling noise. Embarrassingly loud. At this rate I'll go through 8 or 9 motors under warranty

Add another one to the replacement count. Just got my second annual maintenance done at almost 36k for an S85 delivered 09/2014. Looks like I got a "Q" revision based on the part number.
After bearing this noise (ahem, see what I did there?) for maybe 6 - 9 months, it's back to near-silent like it was originally. Hope it stays this way forever.
