1998 AUDI A6 Recalls — Canada & USA

The 1998 Audi A6 has 10 recalls, the most serious being multiple fire risks tied to the headlight switch wiring and fuel system, any of which could result in a cabin or underhood fire. Several recalls center on the headlight switch wiring harness on vehicles with halogen headlights. The knee bolster under the dashboard can press against the harness, connector pins inside the headlight switch can contact each other, or a loose plastic cover on the driver-side support crossmember can allow the harness to short against metal, all leading to fire in the left dashboard area. Vehicles with xenon headlights are not affected by the connector-pin issue. On the fuel side, Quattro models with a fuel vapor leak detection system can spray fuel near an ignition source, and a separate issue involves an incorrect filler neck installed at the factory that does not seal with the fuel cap, allowing fuel to escape. For vehicles with the 2.8L V6 five-valve engine and automatic transmission, ice can build up in the throttle body during extreme cold, causing the throttle to stick open and the engine to hold speed even when the driver lifts off the accelerator. The steering system also has a concern: tie rod seals that do not seat properly can let moisture and debris into the swivel bearing, wearing it down until the steering feels loose and control becomes unpredictable. There is also a fuel gauge issue on Quattro models where sulfur deposits on sending units inside the tank cause the gauge to read full when it is not.
