EPC Light

Some late Audi VW Seat and Skoda cars have an electronic controlled throttle instead of the traditional throttle cable, it is called Electronic Power Control. If the engine ECU (Electronic Control Unit) detects a fault in the system it will put on the EPC light. If the fault is considered serious it will stop the throttle working altogether and the engine will be limited to a 1500 rpm idle speed.

To diagnose the fault correctly the vehicle has to be connected to a diagnostic machine and the fault codes and live data checked.

We have 2 diagnostic machines for this purpose The Bosch KTS system and VAG COM computer system.
