Recall 14V516 affects 1,814 2013 Audi Q7 SUVs for an engine-oil leak into the brake booster. Repair is free at any franchised Audi dealer.
Audi is recalling 1,814 2013 Q7 vehicles with the 3.0L TDI engine because plastic debris can contaminate an engine check valve and let oil leak into the brake booster. Oil in the booster can rupture the diaphragm, causing loss of power brake assist and increasing crash risk; the Audi dealer repair will be free once available.

What's wrong?
The 2013 Audi Q7 with the 3.0L TDI engine uses vacuum assist to help the brake system apply force when you press the pedal. A check valve in that system controls the direction of vacuum and keeps engine-side fluids and pressure changes from moving into the brake booster. The booster is the part that multiplies your pedal force, so braking feels normal without extra leg pressure.
On recalled Q7 SUVs, plastic debris can contaminate that check valve. Once the valve no longer seals as designed, engine oil can pass into the brake booster. Oil inside the booster is not supposed to be there. It interferes with the vacuum-assist system and can leave the brake pedal harder to press than the driver expects.
There is no warning sign before failure. If the booster is already affected, the brake pedal can require more force than normal.
Who's affected?
The scope combines engine cooling and hydraulic brake vacuum hose components for the same vehicle group.

| Units affected | 1,814 |
A matching year and model does not confirm inclusion. Check your VIN to confirm whether your specific SUV is included.
What's the safety risk?
Oil entering the brake booster can rupture the booster diaphragm. That can remove power braking assist, so the brake pedal requires more force and stopping distance can increase, raising crash risk. Schedule the dealer repair soon. Repair will be free at any franchised Audi dealer once available.
What should I do?
- Check your VIN to confirm your 2013 Audi Q7 is included in this recall.
- Contact a franchised Audi dealer to ask about the free vacuum-line replacement and brake-booster inspection.
- Schedule the vacuum-line replacement and brake-booster inspection that address oil contamination in the brake booster and loss of power braking assist.
- Bring the recall notice if Audi mailed one. If not, reference recall number 14V516 and Audi recall 47L8 when you call.
- Drive cautiously until the repair is complete. Leave extra following distance because power braking assist is part of this recall.
What happens at the repair
Once the dealer repair is available, an Audi technician replaces the vacuum line at no charge. The technician also inspects the brake booster system for oil contamination. If oil is present, the dealer replaces the affected brake booster components at no charge. The remedy text says the recall began on September 24, 2014, but this section does not include a current available status, so confirm appointment timing with an Audi dealer before planning service. Parts and labor are covered under the recall once the repair is open.

Frequently asked questions
What is recall 14V516?
Recall 14V516 covers 1,814 2013 Audi Q7 SUVs with a 3.0L TDI engine. A contaminated engine check valve can let oil leak into the brake booster, leading to loss of power braking assist and increased crash risk. Audi dealers replace the vacuum line for free.
What should I do if my 2013 Audi Q7 is on this recall?
Check your VIN to confirm your specific Q7 is included in recall 14V516. If it is, contact a franchised Audi dealer and ask for recall service. The dealer replaces the vacuum line, inspects the brake booster system for oil contamination, and replaces affected components for free.
Is the recall repair free?
Yes. Federal recall law requires the manufacturer to repair the defect at no cost, and the recall remedy says Audi dealers replace the vacuum line for free. If oil contamination is found in the brake booster system, the additional covered components are replaced for free too.
What is the safety risk?
The risk is reduced braking assistance. If oil leaks into the brake booster, the brake booster diaphragm can rupture, causing a loss of power braking assist and increasing crash risk. The dealer repair removes the affected vacuum line and checks the brake booster system for oil contamination.
What if I bought my Audi Q7 used?
The free recall repair still applies. Recall eligibility follows the VIN, not the first owner. Check your VIN to confirm whether your specific 2013 Audi Q7 is included, then call a franchised Audi dealer and reference recall 14V516 when scheduling service.
