ENGINE AND ENGINE COOLING
What Happened
The check valve in your Audi Q7's engine is a tiny part that helps control the flow of engine oil. In some 2013 models built between June 2012 and November 2012, this valve can get clogged with plastic debris and start leaking oil into the brake booster system.
Risk if Unfixed
If oil gets into the brake booster, the diaphragm could burst, making it harder for you to stop your vehicle. This could increase the risk of a crash, especially on the highway or in emergency situations.
Free Fix
Audi will replace a critical vacuum line and inspect the brake booster system for oil contamination. If oil is present, they'll replace additional parts for free. This repair is complimentary, and you should schedule it as soon as possible.
