Can the EPC light come on because of a bad battery alone?

Asked by Jan 04, 2014 at 03:09 AM about the 2002 Volkswagen GTI 1.8T

Question type: Maintenance & Repair

I thought I needed a new battery because I have to jump start my car to get it to run if I
don't start it every few hours. Today the EPC light came on in my car. It is the only light
that is on and I don't notice any other issues besides the battery draining. I was going to
go get a new battery tomorrow but unsure if it is the battery now.

as far as I am aware a bad battery wont cause that light to come on. Go to a parts store like pep boys or autozone and ask them to read the OBDII codes with their scan tool, should be free for them to do it, and that will tell you what's actually going on with the car.

EPC just means "Electronic Power Control," could be like....anything. Step one is replace the battery, since it's bad anyway. Have AutoZone read the code when you pick the battery up and make sure it's not something serious. If the new battery dies, your alternator is gone.

Ive had cars come in with the epc light on, and a low battery =. Once we changed the battery and cleared the code it never came back. So a low battery can cause your epc light to come on.
