Volkswagen Believes It Can Fix 3.0L TDI V-6, Avoid Buybacks
Company Believes V-6 Diesel Engine Can Be Made Compliant With Requirements
Without question, Volkswagen is taking a substantial hit for its emissions cheating on its 2.0L TDI engine, to the tune of more than $10 billion, as we reported earlier this week. And that’s just in the U.S. European regulators are calling for a similar settlement in Europe, where there are millions of affected models on the roads, compared to the comparably modest number of around 480,000 models in the U.S. VW is hoping to avoid the prospect of wholesale buybacks with models equipped with the 3.0L TDI V-6 engine, which include the Volkswagen Touareg and Audi Q5 and Q7 SUVs, as well as the Porsche Cayenne. The company said it believes it can fix the estimated 85,000 TDI V-6 models in the U.S. without having to resort to buybacks, Reuters reports.
Unlike the majority of affected 2.0L TDI models, all 3.0L TDI models sold in the U.S. since introduction have been equipped with a urea selective catalyst reduction (SCR) system, specifically to control NOx emissions, the crux of the U.S. emissions scandal. The likely fix will be increased dosing of the urea solution fluid, requiring more frequent fill-ups of the fluid, but the flipside being the vehicles will meet required NOx emissions standards. The 3.0L TDI vehicles were found to emit as much as nine times as much of the allowable NOx emissions. The 2.0L I-4 TDI models, most of which did not have a SCR aftertreatment system, emitted as much as 40 times the allowable limit of NOx. Until a fix is approved for the 3.0L engine, VW is barred from selling any models equipped with the engine among any of its brands.
