The problem
Volkswagen Group of America, Inc. (Volkswagen) is recalling certain model year 2013 Audi Q7 vehicles manufactured June 5, 2012, to November 29, 2012 and equipped with a 3.0L TDI engine. In the affected vehicles, a check valve in the engine may become contaminated with plastic debris and allow engine oil to leak into the brake booster.
The risk
If oil leaks into the brake booster, the brake booster diaphragm may rupture causing a loss of power braking assist, and increasing the risk of a crash.
The fix
Volkswagen will notify owners, and dealers will replace a vacuum line, free of charge. Dealers will also inspect the brake booster system for oil contamination and, if oil contamination is present, additional components will be replaced, free of charge. The recall began on September 24, 2014. Owners may contact Audi at 1-800-253-2834. Volkswagen's number for this recall is 47L8.
