Hello, my name is***** you for allowing me to assist you! You have a stuck open decay valve in the ABS Hydraulic Control Unit (HCU). That is causing the spongy pedal. Replace the HCU and re bleed the system well. Use the scan tool to actuate the new HCU valves when you bleed it the final time. This should take care of it.
