2015 Audi A5 Warranty Extensions and Programs

Audi has three warranty extensions for the 2015 Audi A5, separate from its recalls. They are for problems with the emissions system, engine and driver assistance systems. Whether one applies to a car depends on its VIN, which an Audi dealer can check.

Warranty extensionAudi AWA-16-08
Dust in the leak detection pressure switch
The problem:
Dust can contaminate the natural vacuum leak detection, or NVLD, pressure switch. Fault codes then turn on the check engine light. Audi says tailpipe emissions are not affected.
The fix:
An Audi dealer checks for free whether the switch caused the light. If it did, the dealer replaces the switch for free.
Who qualifies:
Certain 2011 to 2015 Audis. The bulletin names no model, and an owner letter names the 2013 to 2015 RS5. The faulty switch must have turned the light on and kept it on.
Coverage:
10 years or 120,000 miles from the original in-service date, whichever comes first.
Audi's bulletin (PDF)
Warranty extensionAudi AWA-21-04
Turbocharger failure
The problem:
The turbo can fail. The bulletin does not describe the symptoms.
The fix:
An Audi dealer repairs or replaces a failed turbo, with any parts and labor needed.
Who qualifies:
Certain settlement class cars: 2013 to 2016 A4 sedan and allroad, 2013 to 2017 A5 and Q5, and 2012 to 2015 A6. Cars already repaired still qualify, but totaled cars do not. Each car's term depends on coolant pump work.
Coverage:
At least 14 months from April 12, 2021 or a coolant pump recall. No miles are stated. Ask an Audi dealer for the exact terms.

Warranty extensionAudi AWA-24-04
Automatic emergency braking system faults
The problem:
The automatic emergency braking, or AEB, system can malfunction when its control unit, a camera, the LIDAR or a sensor fails.
The fix:
An Audi dealer repairs the AEB fault and Audi pays 75 percent of the cost. Damage from crashes, impacts, moved sensors or weather is not covered.
Who qualifies:
Certain Audis covered by the settlement, with a confirmed fault in the AEB control unit, cameras, LIDAR or sensors. If the new car warranty's time ran out by May 16, 2024, the extension's time limit was November 16, 2024.
Coverage:
Up to 12 months or 12,000 miles after the new car warranty ends. Ask an Audi dealer for the exact terms.
