Once these engines are fixed, Dieselgate is "over."
Dieselgate caused a huge stir for Volkswagen, but the German automaker has rebounded exceptionally well. Nearly three years later, VW has come up with fixes for its diesel engines – except for one. The 3.0-liter V6 TDI found in the 2011 and 2012 Touareg and Q7 models was still waiting for approval, but a letter from the California Air Resources Board and the US Environmental Protection Agency confirms that a fix is finally available.
The fix will allow VW and Audi to make Touareg and Q7 models compliant with US emissions standards. Approximately 8,800 vehicles in North America will be repaired, completing the seemingly endless Dieselgate saga. Once the repairs are completed, VW and Audi need to submit their plans to resell the vehicles. VW was forced to buy back the cheating diesel cars and pay out to customers.
Audi has been fixing 3.0-liter TDI engines for a while now, but so far only 62% of vehicles in the US and only 42% of vehicles in Canada have been repaired. The EPA document doesn't say how this fix willaffect the engine's performance or fuel economy figures, though we assume both with suffer from the changes
