What should I do if the L throttle controller of SAIC Volkswagen Tiguan fails?

Report the fault code p2 10 100, and the throttle controller can fail. How to solve it? Report the fault code p2 10 100, and the throttle controller can fail. How to solve it? The throttle itself has no fail-safe function, but the program inside the computer has this function. When the throttle fails, the computer will start the fail-safe function to ensure that the vehicle can drive to the 4S shop. At this time, the engine is not controlled by the driver, and the engine is controlled to run at a certain speed according to computer memory. Prevent the engine from working under abnormal conditions. I suggest you replace it in time. @20 19
