this dtc cut is terrible , when cables circuit to gnd car have safe mode, You must disconnect temp sensor and modify software.but egt sensor is unplugged exactly... i even thinking about solder such resistor to switch P1902 dtc, becouse after friend's solution this dtc coming back...

Another thing is no power increase when make power modify... no boost over 2380mbar, but limiters and boost maps set for maximum 2660... Maybe this dtc still keeping car in limp mode..
