This is my observation as well. I keep an eye on the oil pressure and check oil level using BimmerLink.
Haven't made it a priority to swap out the oil pump, but if they extend this warranty to Toyota, I'm jumping on it.
I did mine a few weeks ago. The actual work is easy to take off and put back the seat belts. Sending your old seat belts and waiting it to come back from the vendor took 2 weeks, so plan for that.
Got mine done through Seatbeltmasters on eBay.
Those sensors are expensive!
I replaced mine with a OEM Bosch variant for $60 and it's been working fine, even painted to match the car.

I didn't use any special tool. If you can fit a plier to grip the plastic cap, a firm pull should do. I had to use a pick tool and small flat head screwdriver to get it out. Other than that, maybe a pass through deep socket?
They also updated their instructions PDF.
I haven't driven the car hard enough to really feel any diffence, maybe a tad smoother down shifts?
I can hear the alternator "whine" they mentioned in the vid.
I yanked that knob and it worked!
Some added notes in bold
Detension belt
Remove plastic cap in center of alternator pulley (pry off with a pick)
Hit nut inside current pulley with impact gun to spin it off (impact gun didn't fit the space)
Use a pass through deep socket (22 mm) and hex key to...
There should be plenty of room and the process is easier if you already have a 2 piece charge pipe.
I'm trying to follow their instructions -
Detension belt
Remove plastic cap in center of alternator pulley
Hit nut inside current pulley with impact gun to spin it off
Remove old pulley
