The fan relay could mean your ‘pusher’ fan is in the way out - the electric fan by radiator...
They are PWM controlled and being situated where they are, tend to get water ingress into the electronics, frying them over time. If your in a warm climate this is used by the AC to help drive air over the evaporator.
Worth checking your brakes for corrosion, even wear etc as a PM. The sliders especially on the front can get sticky and cause uneven wear. While your under there, sway bar brackets getting broken is a classic ‘e39 M5 with miles’ issue - they are aluminium and get weaker with age it seems, though they were a bit inadequate to begin with. I replaced mine with steel BMW ones from another model.
Hoping being in LA means your car has minimal rust issues - becoming an issue now for us living in more variable climates...
Chain tensioner as someone else mentioned - due now if not already done and a bit of insurance against chain guide breakage.
Otherwise just drive it, enjoy it and see what happens :-)
