What happened to the ep on the dashboard of mini cooperR50? Ask the great god for an answer

Throttle and thermostat failures have their own phenomena. Check the throttle opening with a computer, and put N gear in place to see the change. If the throttle opening does not change, it is indeed a problem with the throttle motor. If the warm-up time of the thermostat becomes longer as you said, it means that the thermostat may always be in a normally open state, and it should be fine to change it. At the same time, check the water temperature signal of the hot car with a computer.
