A vehicle's Emission Control Light is a generalized indicator that there is fault or possible malfunction in the vehicle's operating system. In some cases, these warning lights will come on if a gas cap is not fully closed. It could any one of a number of sensors such as the o2 sensor or map sensor. The thing to do is have a reputable mechanic/technician run a diagnostics test on the vehicle.

Have you verified that the power steering fluid is at the right level? If it isn't, you need to fill it to the proper level using specific Audi power steering fluid (it's a mineral-oil-like fluid, NOT the stuff you buy at the parts store). If you've run the reservoir dry and kept driving, it's likely you've burned out the pump and will have to replace it.
