Your Audi fuel injectors are an essential part of the fuel delivery system that allows the combustion system to function as it should. If one or more of your Audi fuel injectors has malfunctioned or has completely failed, your vehicle performance will suffer seriously. Some of the symptoms of one of more struggling or failed Audi fuel injectors include a strong odor of fuel in the engine exhaust, an exhaust that has a definite black color to it, excessive fuel usage and significantly decreased fuel mileage, a sudden surging of power, misfiring while the vehicle is in motion, rough running and idling, and stalling. Sometimes Audi fuel injectors malfunction because they are dirty, and while those fuel additives can occasionally help, short of removing the fuel injectors and manually cleaning them, the best solution to dirty fuel injectors is to replace them and take better care of the new ones, by making sure that your fuel filter is clean and taking care to perform routine maintenance procedures regularly, so that the same thing doesn't happen again.
