2009 Audi A6 Warranty Extensions and Programs

Audi has three warranty extensions for the 2009 Audi A6, separate from its recalls. They are for problems with the engine and airbags. Whether one applies to a car depends on its VIN, which an Audi dealer can check.

Warranty extensionAudi AWA-13-07
Carbon buildup in engine secondary air ports
The problem:
Carbon can build up in the engine's secondary air ports. Fault codes then turn on the check engine light, and the car can fail an emissions test.
The fix:
An Audi dealer diagnoses the problem and, if needed, cleans the carbon out of the secondary air ports for free.
Who qualifies:
Certain 2009 to 2012 Audis with the 3.2 engine and 2009 to 2013 Audis with the 3.0T engine. Other causes of the warning light and damage from tuned engine computers are not covered.
Coverage:
10 years or 120,000 miles from the original in-service date, whichever comes first.

Warranty extension
Powertrain warranty after coolant pump seal leaks
The problem:
A seal inside the coolant pump can wear out early and leak coolant. Audi extended the powertrain warranty for certain affected cars.
The fix:
An Audi dealer diagnoses and repairs any problem with the engine, transmission, differential or axles for free.
Who qualifies:
Certain 2009 to 2011 Audis with a 3.0 TFSI, 3.0 TDI or 3.2 FSI engine, in the coolant pump campaign or with a replaced pump. Only the owner Audi wrote to is covered, not later owners.
Coverage:
5 years or 100,000 miles from the original in-service date, whichever comes first.

Warranty extensionAudi AWA-22-04
Takata driver or passenger airbag inflator failure
The problem:
The driver or passenger Takata airbag inflator can fail from a defect. This extension is for cars in the Takata inflator recall.
The fix:
An Audi dealer diagnoses the inflators and replaces a failed inflator for free. Inoperable or totaled cars and salvage, rebuilt or flood titles are not covered.
Who qualifies:
Cars in the Takata recall. After the main term, coverage lasts 75,000 miles from the recall repair or a time limit, whichever is greater: November 10, 2023, or 2 years if repaired after November 10, 2021.
Coverage:
10 years from the recall repair or 150,000 miles from the original in-service date, whichever comes first. Then a further period applies.
