This DIY is useless, it fails to mention the installation procedure and brake line attachment with the reservoir full of brake fluid that will pour everywhere as you try to attach the lines.
The space is really tight and it is almost impossible to attach brake lines with the fluid in the reservoir, especially the pre-charge pump lines.
The air WILL get introduced into the hydraulic system and the only way to bleed it properly is with BWM GT1 tools, as you need to cycle the Precharge Pump, Rerturn Pump, and activate appropriate valves in the DSC module at the same time.
