AMG GLC 43
don't know if I'm correct or not it seems the car program changed around 500 miles,
it was driving me crazy shifting up too high in Comfort, suddenly starting holding a gear longer.
I really feel the car getting better now around 600 miles. When turning in CLA250 3 year lease made me ill,
car seemed like new and I still liked it, I think it broke in about 12000 miles and I turned it in at 21500 miles. They wanted
3k more than resale so I let it go, was too small to be my keeper anyway. I cant imagine I will accept anything
less than AMG again.

just an update : got this done at the dealer under my PPM contract. the tech was extremely nice and apologized since he missed the code on the next screen for "471" that is my vehicle. Im unsure what it would cost without PPM, but it was 3 bottles of fluid, loctite, and some sort of adhesive.

Could you verify that info with MB-USA on cars with code 471 not needing differential fluid change @ 1875 miles and report back for us? We are seeming to get conflicting info from dealerships. Thank you in advance ~

My dealer just changed my rear diff fluid this month (04/19). Covered under my prepaid maintenance plan. According to them, the quickest way to tell if you have a performance diff that needs to be flushed is to look at it and see if it has a heat sink on it.

Agree
If it’s a big deal just do the rear diff at home. Took me 1 hour to do.
also the break in is a hoax. They just don’t want people wrecking their cars and to learn the power before they go all out.
Ive owned many cars and if my Ferrari came broken in with 51 miles then the Mercedes will be fine.
As as I said before drive it hard and seal it all up lol
