My quick Bentley search points to checking the
"throttle actuation potentiometer" and it points to a
procedure on how to check said potentiometer using a
VAG tool. I briefly looked at that procedure and it
is a bit lengthy to summarize here, but it involves
watching the values in a measuring block as you
depress the throttle. It went on to other procedures
to check different components throughout this system.
Another quick search for EPC resulted in a reference
to the fact that a malfunction in the electronic
throttle could cause the EPC lamp to come on.
FWIW, hope that helps ...
