## NHTSA's summary

Under this service action, Audi dealers will replace the starter\-alternator in affected vehicles at no cost to owners. A defective starter\-alternator may inhibit start/stop functionality which could increase CO2 and other emissions while the vehicle is stopped. Emissions still remain within certification standards. Updated affected vehicle chart, owner notification letters, parts and claiming sections to reflect the addition of the final wave of vehicles. Updated criteria in parts section.
