Many people are confused by the differences in bleeding brakes & FLUSHING the brake fluid every 2 years.
THE question was asked whether or not need to connect to the SD laptop when you FLUSH the brake system? & that answer is YES. Otherwise some of the old fluid will remain in the system!
YOU can bleed air from the system w/o connecting the correct equiprment.

IN fact going all of the way back to 1992, the W140 chassis (400SE & 500SEL) required jumping the solenoid on the master cylinder to completely FLUSH the brake system as well.
