Note that the proposed 3.0-liter TDI plan is separate from the 2.0-liter TDI fix that was rejected by CARB on Tuesday.
There are around 13,000 Cayennes on the road that the company needs to repair. Models from 2013 and 2014 would require a new catalytic converter and a software update, but those from 2015 and 2016 would just need the new software. "The technical aspects have all been submitted, we will wait whether there will still be proposals for corrections by the Americans," Porsche CEO Oliver Blume said to Reuters. He wasn't sure how long the repair process would take, but suggested less than half of the affected examples would require the upgraded exhaust hardware.
Blume indicated to Reuters that Audi actually created this repair plan. The EPA first issued a violation notice against the 3.0 TDI in early November and later broadened it to around 85,000 vehicles from the 2009-2016 model years, including diesel examples of the Cayenne, Volkswagen Touareg, Audi A6, A7, A8, Q5, and Q7. Audi later admitted the engine contained previously undisclosed auxiliary emission control devices. CARB gave the automaker 45 days to come up with a recall proposal to fix the 15,000 affected models in the state.
