Volkswagen Passat EPC light and check engine warning with low RPM causing stalling and loss of throttle power on Volkswagen Passat

Some Volkswagen Passat owners report experiencing issues related to the EPC light and check engine warning, which can lead to low RPM, stalling, and loss of throttle power. These problems may indicate trouble with critical components such as the gas pedal, traction control, cruise control, ABS, steering system, and throttle body. Additionally, the EPC light often signals problems with the Electronic Power Control system, potentially resulting in a loss of vehicle power or control. Low RPM and stalling may be linked to throttle system issues, including the accelerator pedal and fuel throttle-body injector. To address the EPC light, some owners find it necessary to check the throttle body and throttle position sensor for debris and consider resetting the EPC system by disconnecting the battery. If low fuel pressure is suspected, it is crucial for owners to promptly check the fuel pressure at the fuel rail using a gauge. Timely attention to these issues is essential for maintaining the safe and optimal performance of the Volkswagen Passat.
