What should I do if the Audi EPC fault light is on and the vehicle shakes?

I just solved this problem today. My car was a 2.0t manual in 2007, and both the EPC light and the sideslip light were on. The car felt dead and did not skid when accelerating. At that time, the 4S shop restored the computer settings, and it returned to normal at that time. Within a few hours, that phenomenon appeared again. According to the master of the 4S shop, EPC and sideslip lights are on, and it is necessary to replace the "throttle harness" connector, that is, cut the original wires and reconnect them in line order, and the problem will be OK. Now speed up and just power! Summarizing this problem is a common problem of this car, and it can be suspected that it is a problem of design or the vehicle itself. After replacement, there is no need to connect a computer for matching. 75 yuan changed a throttle harness in a general repair shop. I hope that netizens who suffer from this problem can refer to it.
