Known issues on the 1994 Audi 100. Three recalls are on federal record for this model year. The first covers the fuel feed line connecting the fuel filter to the engine, which was improperly manufactured by the supplier and can result in fuel leakage. The second covers the ignition switch: defective switches were improperly manufactured and can cause electrical accessories such as turn signals, windshield wipers, lamps, power windows, and air conditioning to malfunction when the car is started. The third covers V6-equipped vehicles' fuel injectors, whose internal seal can malfunction and allow fuel leakage in the engine compartment, which can result in a fire in the presence of an ignition source. Owners have filed 27 complaints for the year and no technical service bulletins are logged. The factory diagnostic and repair procedures behind each of those systems are here.
From tracing a fuel line for leaks to servicing the ignition switch or a full fuel injector inspection, it keeps you on the OEM procedure and the correct specification for your specific 1994 Audi 100.
