MOTOanimus

So I was pulling into work today and accidentally bottomed out, fairly hard, somewhere in the middle of the car. When I came back out 5 hours later and started the car the emissions control system (looks like an engine with a lightning bolt) warning light was on, solid, not flashing. The diagnostic check that runs on the main screen reads OK. I'm thinking maybe I screwed an O2 sensor but I'm also reading about some exhaust valve as well. Any suggestions? It's a 2002 S4 tip. Thanks.

Might have cracked an evap line

Where might I look for the evap lines? Do they run along the exhaust? Thanks for the help.

No they run along the bottom of the car on the left or right side not near the center tube where exhaust is

You should plug in a code reader to see what the code is, that would narrow things down. My best guess would be that you messed up one of your rear O2 sensors.
