you'll fail it right away if the check engine light is on, and they only do an idle test on those S4 cause they're AWD, i don't think there's a roller for all 4 wheels(cept for dyno's), so they only test the idle on all AWD vehicles.(or most, cept for newer which just check for the ecu and check engine light:))
