Things like a transmission filter, new ATF, coolant swap, power steering fluid replacement...

What would be some other things to check for around 100k? Any typical things break or to check on?

Also any recommendations on leather conditioner?

Thanks!

Steering and suspension components, A/C system and braking system. I see that you have an AMG model. How is the supercharger and condition There could be more that I am missing but it all depends on how the car was maintained through out its life and what kind of driving habits the owner before you had.

If not done previously I'd do all the fluids including the often-overlooked differential, too.

Check the front wheel bearings (or if you're not too far from front brakes, repack them at your next brake job and then adjust them). I don't have an AMG, but the grease on mine was looking pretty thin at 112K.

Did you already do spark plugs? If not it's time.

Bosch specs 100K to check/replace the O2 sensors. I'm not sure how to check the things (I'm sure Bosch has a nice bench testing setup but not many of us have that in the garage...) so I just replaced mine, although I did it a bit early because I had to replace the cats and it's lots easier with the pipes out of the car. That said, if you're a DIYer get the splice-in universal Bosch and you'll save some decent money, but it's a tradeoff for the time you spend. The sensors will start slowly getting out of range and you'll lose a bit of economy and perhaps performance; that usually happens long before they trigger a CEL (although often they'll throw codes before that if you happen to check).

Fuel filter if not already done, too.

This summer I've already done the fuel filter, serpentine belt, and spark plugs.

I think my dealer replaced the O2 sensors a little less than a year ago.

Based on your advice then I'll check out the diff fluid, power steering fluid, coolant, and ATF/trans filter. I also read that it's good practice to grease the roof yearly, so I'll do that.

I figure I'll do the pads, rotors, brake fluid, and brake sensor all at once when the pads need to be replaced. I suppose I can also check the wheel bearings at that time as well.

Thanks! Anything else?

It sounds as though you are taking excellent care of her!

There's a DIY on cleaning and regreasing the sunroof here: Are You OBSESSED About Your Benz? | Clean and Re-Grease Your Sunroof.

Repacking the wheel bearings is the same as any other RWD car, but there is the special MB green wheel bearing grease. (If you repack them while wearing nitrile gloves you waste a lot less and stay cleaner, too.) It's more expensive of course, but considering it's only every 100,000 miles, may as well do it right. You'll need to purchase new wheel seals when you do it, too.

Oh, be sure to check the flex discs, too. And when you do the differential, it's always a good idea to unscrew the fill plug first. They can freeze in there and if you drain the fluid first then you're in deep trouble.

would it make sense to simply replace the wheel bearings while they are out?

and is this front or rear we are talking because there is a big difference in the labor on that!
