We thought this iteration of the A4 was the best version of the car we'd ever tested up to that point. It feels solid, handles nimbly and the ride is firm, but well controlled. Braking performance and emergency handling are excellent. The four-cylinder turbocharged engine is smooth and civilized. The cabin is quiet and the interior finish is first-rate. All-wheel drive adds peace of mind, but hurts fuel economy.

AIR BAGS:PASSENGER SIDE FRONTAL
Jun 22 2018
An inflator explosion may result in sharp metal fragments striking the driver or other occupants resulting in serious injury or death.
Summary:
Volkswagen Group of America, Inc. (Volkswagen) is recalling certain 2005-2008 Audi A4 Sedan, A4 Avant, S4 Avant and S4 Sedan, 2007-2008 RS4 Sedan, 2004 RS4 Cabriolet, 2007-2009 A4 Cabriolet and S4 Cabriolet, 2005-2011 A6 Sedan, 2006-2011 A6 Avant, and 2007-2011 S6 Sedan vehicles. These vehicles are equipped with certain air bag inflators assembled as part of the passenger frontal air bag modules used as original equipment or replacement equipment. In the event of a crash necessitating deployment of the passenger frontal air bag, these inflators may explode due to propellant degradation occurring after long-term exposure to absolute humidity and temperature cycling.
What should you do:
Audi has notified owners, and dealers will replace the passenger frontal air bag with an alternate remedy part, free of charge. The recall began June 29, 2018. Owners may contact Audi customer service at 1-800-253-2834. Volkswagen's number for this recall is 69R7. Note: This recall supersedes recalls 16V382, 17V032 and 18V004 and includes vehicles that may have had their air bag previously replaced under one of those campaigns.
