Mercedes-Benz e260l will light up without direction assistance.

Without direction assistance, the EPC of Mercedes e260l will not light up.

The main reason why the EPC fault light is on is that the EPC fault light is on all the time, indicating that there is a fault in the engine management system or electronic control, which is often accompanied by the phenomenon of unstable idle speed of the vehicle or engine jitter during cold start. But for domestic car owners, it is generally caused by domestic oil quality and dirty environment in the car. Drive to the maintenance service station as soon as possible for maintenance, and generally clean the throttle.

Or when the ignition switch is turned on for function check, the indicator EPC will light up. If this indicator lights up while driving, it indicates that the engine power electronic control system is out of order. The engine must be checked immediately. Under normal circumstances, dirty throttle body, vacuum leakage of intake system, broken brake switch and untimely engine upgrade may all lead to EPC failure.
