If you don't have a shop manual, get one. There can be 180bar of residual pressure in the system you are playing w/ dynomite.

WARNING: pressures of up to 180 bar are present at the accumulator.

Follow workshop instructions exactly.

Very interesting, anybody have any insight on how this is bled, I have to replace the one steel line that is shown in the picture, as there was a small battery fire on the car I am working on right now.

Essentially, you charge the accumulator and then disconnect power to the ABS pump. Then you bleed at the accumulator. Close the bleeder valve, and then start the ABS pump to recharge.

Some method of securing the bleeder hose to the valve is recommended. I always had luck with using silicone hose and securing it with a zip-tie.
