After driving my car for about 5 mintues "EPC" lights up on the dash and the car idles around 1500 rpm. I know it has to do with the Airflo sensor, but i threw a check engine light after the car bogged dead in the middle of traffic. plus everytime I stop the car stalls out. Is my car in safemode??

What year is your car? Your MAF may be dead or have you disconnected the battery lately?

The "airflo" sensor? What are you referring to? EPC light while driving usually means a throttle body issue...

Like around how much is an throttle body for a B5 S4?

crank position sensor fixed my epc light. VAG is your friend, if you dont have one go to an autozone!

cps or also know as an engine speed sensor.. i would almost be certain you have a code of p0321 or p0322... see about getting the car scanned...
