What happened to the Touareg epc light?

There are several reasons why epc light is on: epc light is mainly caused by dirty throttle body, which can be solved by cleaning the throttle and re-matching; There is also a leak in the air intake system, which causes the engine control unit to light the epc warning light after detecting the problem; Also, the failure of the brake light switch can also lead to this phenomenon. The main reason why the engine fault light is on is that the throttle valve or the engine has too much carbon deposit, and the mixture ratio is out of balance after the oxygen sensor fails, which is easy to make the engine fault light on. The reason why the new car is bright is probably because it uses lower-grade fuel. Colleagues remind you that if you drive at low speed in urban areas for a long time, this phenomenon is easy to occur. Although it is ok to continue to use the vehicle after the engine fault light is on, such long-term use will definitely increase the fuel consumption of the engine, so I suggest you still determine the cause of the fault and eliminate it. I hope my answer is helpful to you.

Don't forget to give points.
