    Hi all,

    I posted this on MBworld after some confusion between dealers as to what's supposed to happen regarding the mechanical diff service on the non-S W205 C63. Hopefully it helps:

    Here's some news that might benefit other users, as I know there's been some confusion regarding the first diff oil service for the mechanical diff in the base C63. I know most have the C63S with the electronic diff, so I don't think this applies, but hopefully it will help some.

    A little background: when I purchased my C63 in the UK I was told that the car did not need the diff oil changed after a few thousand miles, that the first service would be at a year as per the rest of the MB range.

    The service manual, however, recommended—although didn't enforce—a diff oil service for mechanical diffs at 1,850 miles. With that in mind and that mileage approaching, I called the dealer, who insisted no service was required.

    A while later, a got a call back from the dealer, who had asked around and uncovered a bulletin from 2011 that stated that all AMG vehicles with part number 471 (the same for the W204 C63 PP diff AND the W205 C63 standard diff) will receive a complimentary service when quoting reference number SV-1327, but at 2,000 miles and not 1,850.

    Apparently this information should have been sent to me on week two of ownership, but that was not the case. Why, no one seems to know, and why they are telling people not to get the service, I also don't know, but at least now I can get the service and get it for free.

    Hopefully this information helps some of you as well.

    Just wanted to add the clarification that the C63S should also have this service. Had mine done this morning :)

    Considering that diff would need less than a litre of oil, changing it after a run in period is a no brainer even if you have to pay for the service.

    Thanks for that info. I wasn't aware that both w204 and non S w205 models shared the same LSD.

    There's a long discussion about this on the official AMG PL site, a lot of owners worldwide were unaware of this requirement, both C63 and C63S.

    To be fair to Mercedes my C63 had a sticker on the upper RH corner of the windscreen advising the diff service at 3000km (1800ish miles) along with the running in instructions.

    My dealer was surprised when I asked for the oil to be changed, but I just pointed him to the sticker.....
