Differential service

Rear diff - did the work on my own at about 25 k miles - three or so bottles of Castrol Transmax 75w 140 ran me about $50 to $60 all in. Took me about an hour but I was going real slow cos it was the first E63 rear diff I was doing. Guess if dealer rate is 275 to 300 per hour then your quote is in the ball park.
Front diff - That's supposed to be sealed and you can only get to it supposedly by removing the right side front axle - happy to be corrected if not so. I had mine done under extended warranty at the dealer because it started to leak - that worked out real good for me - zero cost with a full front diff service. Was told that fixing that leak would have been in the high 5k area without my extended warranty.
Tranny fluid change: done at an independent and I supplied parts/fluids Tranny pan, filter, 10 liters Liqui Moly Toptec 1950 tranny fluid, some tools and adapters for the job - roughly $300 for parts. Labor at my indy guy was about $350 but that included a transfer case fluid change too ( note the transfer case fluid is a different fluid than the tranny - think back to the older 7 speed MB trannies from the mid 20-teens - it is that fluid - Fuchs Titan 7134 FE was what I used ). So I got away with a roughly $700 or so parts and labor cost for my tranny service and the transfer case.
Front diff isn't on any service interval I can find, so as OBP mentioned, would only tackle that if there was a problem.

The service schedule for the S213 is pinned somewhere. I posted it a year ago and the admin pinned it. A discussion of the front diff is also in that thread.
