SACRAMENTO, California — Audi, Volkswagen and Porsche have been ordered to recall and repair illegal emissions software in all 3.0-liter V6 TDI diesel vehicles from model years 2009-'15 sold in California, the California Air Resources Board said last week.
The automakers have 45 business days from November 25 to put together a recall plan and deliver it to CARB. The order affects about 15,000 California vehicles out of approximately 85,000 sold in the U.S. with diesel engines supplied by Audi.
Audi said earlier that its 3.0-liter diesel vehicles sold since 2009 contain so-called "auxiliary emissions control devices" that weren't properly disclosed to U.S. regulators.
An Audi spokesperson on Friday told Edmunds the CARB filing and time frame was expected.
"We fully intend to work on solutions to present to regulators within this window of time," the Audi spokesperson said. "We take this very seriously and treat responses to the agencies as a solemn responsibility."
Porsche said in a statement it will "continue its efforts to comply fully with all regulatory authorities."
It added: "Porsche awaits detailed information from the engine supplier, Audi AG, as to the specific actions which will be necessary to correct and recertify the 3.0 liter V6 diesel engine."
Audi earlier this month said it will revise emissions-control software on Volkswagen Group vehicles with 3.0-liter diesel engines in the U.S. to comply with clean air laws. It will also extend its U.S. stop-sale on new VW, Audi and Porsche models with 3.0-liter V6 TDI diesel engines "until further notice."
The engine is used on diesel versions of the Audi A6, A7, A8, Q5 and Q7 starting in the 2009 model year. It has also been used in the Volkswagen Touareg and Porsche Cayenne SUVs since model year 2013.
Edmunds says: Owners of these vehicles are still in a holding pattern, but at least the clock has now started on a recall plan.
