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,

Hard to tell. EPC (Electronic Power Control) faults show up when one of the sensors (and the A7 has dozens of those) gives a reading that falls outside of the predetermined limits. That can be related to fuel, ignition, air flow etc.

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.
