Audi A6 2007 V 6 2.4 L
Problem: Engine Protection Control (EPC) appear after car start for almost 20 min referring to this code P0642, even if the car is not moving. If the EPC light is on, I have to turn off the car until it cool down completely, and it will start again like nothing happened, and again only for almost 20 min.

This code indicates an issue with the ECM. Here is some info for you.
