Adafruit: From Ultimate Driving Machine to Ultimate Rent-Seeking Machine: The BMW Logo Screw Patent.
If you haven’t already heard, BMW’s R&D teams have been busy “innovating.” Unfortunately, they aren’t focusing on the things that actually matter—like stellar engine performance or the legendary driving dynamics that gearheads love.

VW made these funky triangle topped bolt on TDi injection pumps ( or maybe it was Bosch who cares). My buddy who’s a mechanic said “don’t mess with those ,you need special sockets”.
I took 12pt sockets and used a dremmel to grind out every other two points in the socket and had my own set to mess with the bolts they didn’t want me messing with.
