AUDI S4 Recalls

The Audi S4 has 4 recalls spanning 1992 to 2015, with the most serious being a fuel line defect on 2013–2015 models where the front airbags can fail to deploy in a secondary frontal impact, raising the risk of occupant injury. On those same 2013–2015 vehicles, the front airbag control system can miss a second collision event and leave occupants unprotected at the moment they most need the bags to fire. The 2003 model year has a separate issue affecting xenon headlamps, including those on cabriolet versions, where the lens coating degrades over time and reduces how much light the headlamps project. This narrows the driver's effective field of view at night and raises the chance of a crash. Going back to the earliest production, the 1992 S4 has a fuel feed line between the fuel filter and the engine that can shrink and pull away from its fitting due to heat from the turbocharger, allowing fuel to seep out near hot engine components.
