I’ve also changed my turbo control valve, fuel pressure sensor and map sensor recently and can really feel the difference

+1 on the lower coolant "T" piece hose. I couldnt even see this crack because it sits face down ontop of the gearbox, but there were lots of white coolant marks around the gearbox as a giveaway sign. That, and the coolant leaking onto the ground! If you keep losing coolant, it will either be this pipe, or a crack in the actual coolant tank.
