Hay guys I'm new to this I have a 05 Audi A6 3.2 Quatro I just changed the rear brakes and alot of air got into the lines, so I'm having a problem bleeding them I used a one person bleeder and also the brake method. Still my brakes are still soft, with more looking into it I found that my platic electronic box behind the rear brake caliber is cracked could that be what causing air to remain trapped inside it doesn't seem like it get any brake fluid in it but I'm sure you could help with that please and thank you for any help I don't wanna buy the platic back if I don't need to I just enlisted in the airforce and go laid of work. So money is tight at least until I get sent to basic training

I suspect you have an Electronic Parking Brake (EPB) equipped car, i.e., the parking brake is electrically operated by a switch on the central console near the transmission selection lever.

That plastic box is most likely a cover for a connector to the electric motor that operates the parking brake.
When pads are changed on the rear of a car with EPB the adjuster must be electrically withdrawn (well, there is a way to do it mechanically but you have to take stuff apart) before the new pads are inserted. VCDS is one way to reverse the pad adjusters.

If you forced the pads out with some sort of mechanical spreader you probably effed up the system.
