What is the EPC lamp of Shanghai Volkswagen? thank you

EPC stands for engine electronic stability system. The indicator light is always on, indicating that there is something wrong with the engine and electronic system. If the indicator light is always on or flashing after ignition or driving, the management system has detected engine or electronic system failure. Please contact the service station immediately.

Of course, if the engine is turned off due to improper operation, this indicator light will also light up to laugh at you, and it will light up again after ignition.

Extinguishing means everything is normal. 95% of the reason why EPC lights are turned on frequently is that the electronic throttle is dirty. Need cleaning
