Audi q5 cold car is not easy to start, it will turn off, and the hot car is normal. What is the reason?

Hello, according to the situation you described, do you need to check whether there is a fault? If there is no fault code, there is something wrong with the water temperature sensor or the engine has too much carbon deposit. You need to clean the throttle valve and fuel nozzle. I hope my answer can help you. If there is anything you don't understand, please feel free to consult me. Have a nice trip. Thank you for asking the owner if you have any questions. 4S shop professional technician, 10 minutes to solve.
