Engine oil, I keep it to a year on the M3 due to a ton of short trips which is high wear and also condensation issues.
The X5 being a plugin the engine actually rarely comes on. I'm debating stretching that out to two years since the engine itself does maybe 1000km a year while the EV part of the drivetrain does the rest.
Brake fluid intervals from manufacturer are usually quite generous at around 4 years. At even say $200 a change it's nothing. Granted I've only ever cooked my fluid once, it was on my parents Caravan, I picked it up from the mechanic and went to pick up my gf from work and went to have dinner. The new pads they put on has a scrubbing layer which generated a lot of heat and it cooked the old fluid and the pedal went to the ground. Took pumps to get the van to stop.
Diff/tranny - 4 years. Do it together with the brake fluid. I don't buy the lifetime fill BS. Just learned that the transfer case on the ZF8 is weak, the interval is 4 years but there's no guarantee it will last that long. Our X5 just got a new transfer case under warranty.
