Q: EPC light on an now I have no power, brake an battery light is flashing

You probably have a dead battery. The computer systems on your car will be prone to odd behaviors when the battery voltage gets low, so you may see lots of things that don’t make sense. The battery could be dead for a number of reasons, top of the list is a malfunctioning charging system. Or it may just be the age of the battery. In any case, it will be necessary to perform some tests to see if that’s really what is wrong. As for the EPC, which is the system that controls the electronic throttle, that may require some separate diagnostic work after battery voltage is restored. You can have this conveniently checked out by contacting Your Mechanic. They can send a technician to your home or office to check out your Audi electrical system and give you an idea on what it is going to take to fix it.
