Fortunately, being a car enthusiast over the years, I've made some good friends with the proper tools so if a scanner helps, I'm sure we can have that area covered.
Over on the Subaru pages, there were mass concerns about using anything other than the proprietary trans fluid, even tho companies like Amsoil claim to compatible, the community highly advised against it as it could damage the CVT transmissions. (The CVT may be the bigger culprit.)

Did you find out what specifications is needed for the GLB 35 transmission fluid? If so, look up the brand you prefer here: https://operatingfluids.mercedes-ben...egory/gear-oil

I believe certification needed for the GLB 35 is 236.22 but I am not 100% sure, if it is indeed 236.22, here is the brands:https://operatingfluids.mercedes-benz.com/sheet/236.22
I mean, it is not a lot of brands to choose from.

The DCT in the GLB is sturdy and reliable. However, the wet clutches will wear quickly if the friction characteristics of the fluid have deteriorated. Change on schedule or earlier.
Xentry is not necessary ONLY IF the complete service procedure is available or known. Then a scanner with dedicated current MB software can be used. I farmed mine out because of this.
BTW - It would be great if you could document your fluid change and post it for other users.

I agree @JettaRed we are planning on doing 5k intervals for oil changes.
Would everyone agree that the brake fluid must be changed out every 20k as well? Even cabin filters every 20K? Cabin filters are inexpensive enough, but the brake fluid job seems a bit extreme...or am I being ignorant? Any insight is appreciated!

A brake fluid flush should be inexpensive if you do it yourself. The most expensive part should be getting the proper fluid. Use a fluid transfer pump to presurize the fluid to about 10-15 psi, and then open the bleed screws in sequence for each wheel, usually starting with the furthest from the reservoir. There are plenty of YouTube videos on how to do it.

The GLB transmission fluid is not proprietary, but it’s not cheap. And DO NOT use aftermarket filters. Fluid + filters will run $250+.

I'll definitely stick to the scheduled maintenance at the very least. My wife will be doing most the driving and will keep it in comfort mode, so I hope it doesn't see more than typical wear.
I do plan on making a thread for the 35 and using it as a maintenance log of sorts to document it as best I can for when the time arises.
Brake fluid should be changed every two years regardless of mileage. That is because brake fluid attract water (moisture in the air) and that water can corrode brake line components. While that usually takes longer than two years, two years is a safe and recommended interval. You can always get an inexpensive brake fluid tester to see what the condition of your fluid is.

Appreciate this info! Still about 30k miles from the service but want to start getting familiar with what is needed and be prepared for when the time comes. Extremely helpful!!
OEM is the only way!...in most cases

I'm somewhat well versed when it comes to changing out the brake fluid on certain cars, in a poor-man's way...I've done a few BBK's on past vehicles and I'm almost embarrassed to admit how many bottles of brake fluid I've gone through. May be time to invest in some proper tools!

You might want to occasionally drive it to a few cycles of high RPMs (especially if in stop and go traffic for a long time) to burn off the condensation and carbon (there is a reason why the Italian tuneup exists), just make sure the engine oil and coolant temperature and transmission temperature is up to the operating temperatures first.
As I get older, I'm more gauged to the idea of having proper tools, even though I may only use it a handful of times, ha.

On longer trips, I'll be doing most the driving and I'm sure I'll get it into Sports+ mode a few times...otherwise, it's mostly highway miles to and from work with about 30% stop and go miles.
