Autowerke techs simply pump the clutch pedal about 50 times to bleed the system after cdv mod. It's a SELF-BLEEDING system. The pedal will often drop to the floor due to air entrainment at the beginning. As it is pumped, however, it returns to normal travel length and friction as the air is expelled. You must push AND pull the clutch pedal at the beginning due to this. You will see the air bubble into the reservoir tank. Consequently, the reservoir tank cap must be OPEN to use this technique or the pressure accumulation will negate any significant bleeding.
DO NOT clamp the lines.
DO NOT drill the cdv
DO refill the reservoir tank
DO open the reservoir tank refill cap
NO NEED to use the bleed valve
Good luck!
