It must be a power bleed procedure in the ABS menu and it should lead you step by step... i have only the classic hawkeye but it should be quite the same

It says refer modulator bleed procedure in instructions and continue, I haven’t got any paper work with it and I can’t find these instructions online

Go ahead in the menu cos it should lead you on the screen, i atach you what i have about Hawkeye pro which IMO is the same with Total it was jus re-branded

All it says after that is hold brake pedal? There’s no real instructions

IIRC it lead me to open each beed nipple and so on though i might confuse it with nanocom cos it was long time ago. You'll have to be handy and figure it out yourself but if air got into the modulator that can be the reason for the sinking pedal unless the master cylinder gave up the ghost.

Does it drop with engine running?

Yeah brakes feel really really good now but yes It does drop a little when you press with engine running
So pleased you have sorted it out so cheaply. Like @sierrafery I too have never seen oil in the MAP plug, the Red ECU plug yes, even years after changing the injector harness.
But the MAP also gets very dirty, so if you keep on cleaning it and the sensor you should find it keeps running well.
Brilliant outcome!
It should do, that's the servo business!
If you want to check the servo. Turn the engine off then keep pressing the pedal. It should go really hard. Then pressurise the pedal, keep your foot on the pedal then start the car. Your foot should sink a little then firm up. Proves the servo is working OK.
