For the past couple of days, I've had my EPC light come on while driving in traffic. I wasn't doing anything out of the ordinary, and I wasn't particularly pushing the car hard. Both times it's happened, I was accelerating.

The car has 70k miles on it. I bought it at 40k miles 18 months ago. I've never replaced the battery, so I'm hoping it's just an old battery causing this or something...

I'm going in for service as soon as they will take me.

Any ideas?
