Recall 14V667 affects 101,938 2013-2015 Audi S4, Allroad, and A4 Allroad vehicles for faulty air bag software. Free update at any franchised Audi dealer.
Audi is recalling 101,938 2013-2015 S4, Allroad, and A4 Allroad vehicles because an improper air bag control module algorithm can leave the front air bags undeployed during a second front impact after a crash that deploys the side air bags. That raises the risk of occupant injury, and Audi dealers will complete the repair free of charge.

What's wrong?
The air bag control module in 2013-2015 Audi S4, Allroad, and A4 Allroad vehicles is the computer that reads crash sensors and decides which air bags deploy. In a side crash, it should command the side air bags, then keep evaluating the vehicle for another impact. If the front of the vehicle is hit after that, the module should command the front air bags when the crash conditions call for them.
On affected Audis, the problem is improper coding in that control module. After a crash that requires side air bag deployment, the module can fail to send the command for the front air bags during a later front impact. That means the front air bags do not deploy when they are needed for that part of the crash.
There is no warning sign before failure. The issue is inside the control module software, so an owner would not hear, feel, or see it during normal driving.
Who's affected?

What's the safety risk?
In a secondary front impact, the front air bags can fail to deploy, which increases the risk of occupant injury. There is no warning sign listed before this failure, so confirm whether your VIN is included and schedule the software update soon. Repair is free at any franchised Audi dealer.
What should I do?
- Check your VIN to confirm your 2013-2015 Audi S4, Allroad, or A4 Allroad is included in this recall.
- Contact a franchised Audi dealer to schedule the free air bag control unit software update that fixes the deployment-command problem.
- Bring the recall notice if Audi mailed one. If not, reference recall number 14V667 when you call.
- Drive cautiously until the software update is complete; the issue involves front air bag deployment after a secondary front impact.
- Call Audi customer service at 1-800-822-2834 with questions, and mention Audi recall 69K5.
What happens at the repair
At the dealer, an Audi technician updates the air bag control unit software so the module uses the corrected deployment logic for the side and front air bags. The software update is free under recall 14V667, and parts and labor are covered. Audi has a general reimbursement plan on file for owners who already paid out of pocket for the same software related recall repair before the notice. Bring receipts or repair documents to the service desk and ask Audi customer service how to submit the claim.
