Rear Axle Oil Change No Longer Needed at 2K?
The service guy tells me they did extensive research on this last week when the owner of an Edition One showed up for the 2k service and found out it was not required -- so it wasn't done on his car either. They say that 2k requirement is for the W204 model.
Anyone else here get this feedback? Did MB change this requirement recently?

I don't know of any LSD that doesn't require a break-in oil change. Do a Google search on various aftermarket LSDs. They always require it. My dealer was clueless as well, but I told them to do it anyway.
My dealer and my windsheild sticker from AMG says DO IT.
It's not much money.
GL.
My 70 yr old dad say it's not necessary... but he says I should only pay $24/tire..... at least that's what he paid in 1973 for his cutlas

My father-in-law (in his 70s) is a auto geek and would kill me if he knew I was letting someone touch my car at today's labor rates. He thinks you should offer the repair guy a cup of coffee for the work. Otherwise, put on your "gosh darn it" overalls and do it yurself

My dealer spent all last week looking it up, and their conclusion was that the rear differential fluid change was NOT required. They said it was due to the S-model having an electronic LSD instead of the mechanical LSD on the non-S model.
The mechanic there is one of the very, very few people I'd allow to touch my car, so I'm definitely inclined to believe him.

some dealers say it is needed and
the UK manual says it is needed and
One owner contacted AMG and they say it is needed and
Past experience says it is needed
So I am inclined to do it at 2k miles along with the not needed oil change
I don't have sticker in front of me, but I don't recall it saying I needed the change.
I remember the salesman and service tech both reading the sticker and consulting whatever they used to look it up at delivery, and both said it didn't need to be done. They both were working under the assumption that all AMG models needed the change, but they looked at whatever they did and determined that it didn't. They also last week consulted whatever they needed to do and still said it didn't need to be done.
Not trying to argue, just stating my personal experience.

Her Owner Manual (not service sheet, not PPM schedule, but the big, thick book in the glovebox) had a section on break-in. It had a paragraph in there that stated specifically that her AMG-model CLS needed the differential service. I've attached a PDF of the 'Break-In' page in her manual.
I went online to get the Owner Manual for the MY15 C-class, both for the Sedan and Coupe. I've attached PDFs of the 'Break-In' sections from each manual. The Coupe has the same language as the CLS; it says the differential service in required. If you look at the Sedan, nowhere in that section does it say any of the MY15 C-class sedans require the service.
I understand many will disagree with me. That's fine. I'd rather go by what my trusted service tech tells me and what my Owner Manual tells me.

This one has all the AMG info in it that the one you show does not.

They checked with the technical team and if you have an S model it is a sealed unit and therefore cannot have the oil changed - it is only required on standard C63 not the S version, as that has a mechanical not electronic device.
I'm not sure if this varies depending on whether the car was made in the US or Germany.
Either way, they have put notes on my customer record stating that they told me it is not required and therefore if there are any issues in the future relating to a lack of oil change they will cover any repair costs under warranty.

If it is sealed and can not be done how did 4 of the posters above have it done to their C63S cars?????
