Failed Brake flush

Hey guys I need some help with a brake flush on an 05 R230. I was bleeding my brakes using a mitey vac. I wasn't paying attention and didn't fill the reservoir in time and got air in the system. Immediately after, with the engine off and stepping on the brake, I got a RED "Reduce Braking effect start engine".


I ended up getting a Motive pump power bleeder and re-bled the brakes with about 2 liters of fluid. But I'm still getting the brake error. I'm assuming air got into the abs or something. Any other place I can try to bleed air out of the system.


The brake pump still kicks in when you open and close the door and the brakes were fine before my goofed up bleed. Any advice would be appreciated. Thanks.

I think you may need a Star system to power bleed the system.
