2000 Mile Rear Diff Service?

Read on this Forum that C63S requires a rear diff service at 2K miles... Is this true? My dealer (Rusnak in Arcadia) didn't seem to know off the top of his head - but came back and said yes, it is required and the cost is $395.00. Not a lot of money but seems a bit pricey just to change the rear diff oil and plug...

Yes it's required at 2k miles but price is abit high. I paid 280 last month and that's even too much but what can ya do. I would have done it myself but I wanted it to be on record. Fair price would be $200. I've seen people pay $160 but each dealership has its own charge.

why can't you just buy the fluid and change it yourself? All you need to do is keep the receipts and time stamp them?

Yes u can do it yourself the fluid and 2 new plugs are about $70. I thought because of having a electronic diff in my S they had to do something with the computer like in the c43 but I guess they don't.

Rear Diff oil change - Do it yourself

It's easy, assuming you can get the car up on ramps/stands and level.

This way you'll know it's actually done.

My wife’s 2018 AMG GLS 63 came with this same sticker so I plan to have the rear differential fluid changed at our local dollar and am told it is around $200. I drive BMW M cars and 1,200 mile break in services are common but was surprised her SUV needed it.

I'm pretty sure the GLS63 doesn't require the rear differential service nor do any 4-Matic AMG models outside of the CLA-based cars. I have a family member that has one ('18 GLS63), and they didn't require it. Also just looked through the maintenance schedule too, and in the part where its shows that the C-class and others need the service, it shows that the GLS doesn't.

I would recommend doing a diff fluid change on any high performance car or suv after initial break in to remove all metal shavings and ensure the fluid isn’t under filled from the factory, which is very common on some cars. You’re talking a $30 bottle of oil and a $20 fluid pump then you can do it yourself in about 30 minutes or $200~ to have it done and keep everything working at its best for many miles ahead.

I read the same thing in the manual but when I bought the car, they showed me a manual that indicated a 1,875 mile rear differential service was needed and I had a sticker on the windshield as well. Replaced the rear differential fluid at our local dealer yesterday for $199 and changed the oil too for good measure.
