EPC fault code

I installed an AWE exhaust on my 2012 A7. The sound is great but I am getting a fault code (EPC). I hope this isn't a result of the install. The car is still under warranty so I hope this won't be an issue. Any thoughts would be appreciated.
Thanks,
Kirk

The only way to tell exactly is to have the dealer do a scan that tells what sensor is reporting the out of range condition.
