The California Air Resources Board (CARB) today rejected proposed recall plans submitted by Volkswagen/Audi and Porsche for repair of undisclosed Auxiliary Emission Control Devices (AECDs) and defeat devices in 3.0 liter, diesel passenger cars manufactured for model years 2009-2016. This decision affects about 16,000 3.0 liter diesel Volkswagens, Audis and Porsches sold in California.

CARB staff has determined that the proposed recall plans submitted by the companies are incomplete and deficient in a number of areas (see links below for rejection letters).

CARB, in conjunction with EPA, will continue the on-going technical discussions with the companies through the enforcement process to ensure a legally and technically acceptable resolution is reached which fully mitigates the excess emissions.
