2019 C63: Locking differential oil change
I entertained the idea of changing at 1K miles but my service advisor talked me out of it saying it wasn’t necessary. Might do one at 5K. Thoughts?

If you want to change it, go for it. More than likely won't hurt anything. But it isn't (and wasn't) required anymore.

What do you mean by dealer honoring it, I'm sure they're happy to take our money even if the service is unnecessary.

I have 1,400 miles and will call Dealership this week to see what's what. If they say we will do it then I'll bring it in.
I agree - it'd be nice if there was some form of consistency from MB on this. Spending the time / money to change the oil may not be much, but if you kill your rear diff and they point to a lack of oil change as the reason, it could mess with a warranty claim.

I called and asked a local dealership about it and they were more than happy to tell me it needed to be done, and also quoted $300ish for it, so I don't have a lot of faith in that dealership anymore. Hell, they wanted $42 for ONE of the replacement drain plugs for the diff cover.
I'm going to do the change because, as others have pointed out - it can't hurt, and the questionable nature of the need tells me to lean on the side of caution.

I'm new to the forum and I had previously owned a C250. I have finally upgraded to my dream car. I bought a 2019 C63s Sedan and picking it up on the 27th June. I'm super excited and will checking these forums regularly.
I'm based out of Melbourne, Australia and I'm so confused with a few things. I'll be speaking to my SA and figuring it all out but I wanted to be prepared before I asked for anything or making sure its all hunky dory.
If you guys can help with the following that would be awesome.
1- Break in period - some owners saying it is not necessary
2- Diff oil change - I'm on a free 3 year servicing plan, will this be required? If it is I know it will be included.
3- I'm a bit worried about the pops and crackles conversations going on in different threads. The Australian version of the C63s - is this going to be affected by quieter exhausts due to the EU regulations?
4- Is paint protection worth it? or interior leather protection from permaguard? The dealer is trying to sell me that post the sale. I was thinking a clear PPF or a stain finish. (the color of my car is Selenite Grey - metallic with black multi-spoke wheels)
When I test drove the 2019, it was loud and popping and crackling all along the test drive. I pushed it pretty hard.
Any input be highly valued.
Thanks

Any thoughts and suggestions will be welcomed.
Pops and crackles is a different issue which will hopefully be addressed.
Personally, I prefer the odd ‘rifle shot ‘ crackle or two. No more.

My 2019 E63S just had its rear-end oil changed for free on the prepaid maintenance plan. This dealer, at least, has not had any instruction to stop doing this and they are quite a large AMG center.
