The 4S shop cleaned the throttle valve, and the three-way catalytic converter blocked the fault light. During the warranty period of the car. The 4s shop asked me to handle it at my own expense. Who will bear this responsibility? First of all, we must find out the appraisal result of 4S shop. Simply from the phenomenon, cleaning the throttle and blocking the three-way catalytic converter have little to do with product quality, but are related to driving operation and oil products. If the 4S shop authenticates this way, the car will not be treated for free even during the warranty period, and it will definitely be charged because it is not a quality problem. Therefore, this responsibility should be borne by the owner.
