I had a 2002 Chrysler Town and Country, made when they were owned by Mercedes. The owners manual had large warnings the it had to be towed to a Chrysler dealer if the brakes needed bleeding. I asked my mechanic about it and he said, well we have had a lot of problems bleeding them, let me ask my computer guy, he was supposed to be finding out about this.
The computer guy said, that Mercedes would not release the computer code to anyone but their dealers that you needed to open the valves in the ABS. A couple of years later I asked again and he said, yes, they had been forced to release the codes.
Because of this and the fact the dealer wanted $200 to bleed the brakes, I just used a turkey baster to remove the fluid and refilled it 3 weeks in a row. I will admit I did not actually try bleeding them because I didn’t want to take a chance on disabling the car.
I recently bled the brakes using a one man bleeder kit on my 2012 Camry and it was quick and easy.
