What are the intervals for replacing "big" service items like trans and brake fluid?

I'm readying myself to buy a cpo glc63s. I like to know what the costs are and what is reasonable.

inb4 if you have to ask you can't afford it.

I googled about service a and service b and supposedly they're glorified oil changes. I'll most likely be taking it in for regular service to an independent mercedes shop for about half the price. in canada, service a is 600, service b is 1000, not including tax, for an amg at least.

I googled the manual for a glc63s and couldn't find info on intervals. I know oil change is about 1 year/10000miles.

Mercedes replaces transmission and/or brake fluid every 2 years which is supposedly ridiculous. Does anyone know what the actual intervals should be? I thought it was more like 50000+ miles for transmission fluid, and 20000-30000 miles for brake fluid? I only drive my car about 10000KMS a year though.

Aside from filters, trans, brake, and oil fluid, and brake pads, any other big maintenance items i should know about? I don't know if anything extra cause amg and biturbo.

Some questions

1) Remote key fob battery replaced every year, I assume it's something I can do myself or is it purposefully difficult and need a welder or something. My last key fob only needed to be changed after 4 years.

2) I know most of these fluids and filters, but what is rear axle differential fluid, is this related to awd, a drivetrain i've never had before? Is it expensive/difficult, or about same as an oil change? I'm guessing my last car, a 2015 mustang GT didn't have this?

3) "Dust filter replacement gle/gls only". other cars don't have a dust filter?!

Brake fluid is every 2 years at a B service according to them. I think every 4 years is plenty unless you track the car. The rest of the things will vary by total vehicle mileage and the diff services are different for the AMG models. I'd try to get the maintenance sheet from your dealer before purchase.

The reality is, most of them are still only simple fluid changes (The transmission requires more tools and has a special filling system, but still can be done DIY), and if you have a trusted mechanic or are handy yourself, can save you literally thousands of dollars in service costs over a couple of years vs. paying the dealer to do it.

It's easy to do. The reason it's annual is it's now a standard 3V coin-cell battery instead of a larger $100 lithium thing.

When did it ever cost a $100 to replace a key fob battery.

That's what my dealer told me it would cost before I bought the car and then when I got a 2020 model he said it was cheap because of the new key fob batteries. From a quick google it seems the only difference is that the 2020's use 1x coincell instead of 2x. I guess it was yet more dealer BS.

I've had 5 mercedes over the years with 3 different key fob variations and its always been an $8 dollar battery from CVS.
I guess if the dealer is replacing it you would pay that much but it is easy to do yourself.

It does not seem that GLC63 has the LSD(limited slip differential) for the rear axle as per the document. But need to be confirmed.

It is to lock/limit the rear axle differential so that both wheels(left and right) turn on same/similar speed. It is very useful if want to drifting when turning the car. I think GLC63 can be drifting easily. I guess it should have this LSD.
