Correct there is only one thermostat in the BAD Fsi used in A2, I got the two thermostat operation from SSP_296 for the BAG Fsi used in VW.I thought there was only one thermostat, controlling the lower circuit with dual opening points, 110 for general driving and 87 for high speed driving. The lower temperature achieved with heater resistor in the wax stat. (This came from SSP222, which although it describes the FSI's "Electronically Mapped Coolant System" is not A2 specific).
