Has anyone done on the c43 ? If so how difficult is the job if self done and oem fluids or motul ?, I was gonna go w motul as that’s what I use for my srt but just playing on the safe side w the Benz

MB said the diff is a sealed unit. But few who had their diff warrantied, service changed the fluid first because it was faster and cheaper but ended up getting them the new diff.

So lifespan of diff fluid is probably when the warranty ends so will see you back here in 3 to 4 years.

My car just hit 60k and I went to the service advisor at Benz to talk to him since I never get my services done at MB, he said by 60k the differential fluid needs to be changed for the rear wheels

Got mine done at an indy shop in Toronto. Did it while I also did trans fluid, pan and filter. 700 bucks for all of it using oem parts and fluid. Got it done early tho around 50K (KMS)
