Audi B7 A4 Cabriolet with xenon headlights: reflectors to be replaced
In July 2005, a recall was issued for Audi B6 A4 Cabriolet vehicles fitted with xenon headlights so that the reflectors could be replaced since the brightness of the original reflectors could decline over time (PRA 2005/7898).
Audi B6 A4 Cabriolet: Takata airbag recall
In August 2018, a recall was issued for Audi B6 A4 Cabriolet vehicles. The Takata driver’s airbag in these vehicles contained propellant wafers that could absorb moisture over time. In the event of a collision which triggered the driver’s airbag, excessive internal pressure could cause the metal airbag inflator housing to explode. This, in turn, would cause the metal fragments to be projected through the airbag cushion and into the cabin – these fragments posed a serious risk of injury and fatality. For the VINs of the recalled vehicles, please see PRA 2018/16949.

- The anti-lock braking system (ABS) may activate unnecessarily under normal to light braking pressure due to cracks in tone/exciter rings (rings on the outer CV shaft that measure wheel rotation).
- When the oil filter is removed, the oil cooler is susceptible to turning – this may damage the coolant lines and cause a coolant leak.
- For the 1.8-litre turbocharged petrol engine, the throttle body control valve may sludge up, causing a very low or uneven idle.
