Volkswagen Nearing Fixes for Engines Affected by Dieselgate


Volkswagen has been hard at work trying to right its wrongs in the wake of being exposed for engineering “cheats” on emissions for its various diesel engines. Now there is word that VW has come up with a solution, though, what that means for U.S. versus European owners may vary.

Volkswagen is seeking approval from regulators to employ a series of low-cost “fixes” on its 1.6-liter and 2.0-liter EA189 four-cylinder diesel engines. If approved this would make the roughly 8.5 million “rigged” diesel Volkswagens in Europe emissions-compliant.


According to the UK’s Car Magazine, the fix for the 1.6-liter engine involves a new “flow transformer” as well as a software update. This flow transformer consists of aerodynamic mesh installed in the intake system in front of the mass air flow sensor. This insert calms the air passing through the sensor, resulting in more accurate readings. The software component is said to remove the “defeat device” software that allowed millions of diesel engines to skirt diesel regulations.


As for the 2.0-liter engines, a simple software update will solve the problem, and that fix should only take 30 minutes. So what, then for American owners of the affected diesel vehicles? Bloomberg reports Volkswagen has submitted its plans to repair roughly half a million affected vehicles in the U.S. with the 2.0-liter diesel engine. The automaker is awaiting a response, which is expected sometime in December. There is also the matter of the larger 3.0-liter diesel V6, found in roughly 85,000 select VW, Audi, and Porsche vehicles. Volkswagen plans on altering the software in these engines and resubmit the fix to American regulators for approval.

As for the internal workings at VW, a program set up to encourage those involved to come forward with details and encourages whistle-blowing expires soon. The automaker plans to share the initial results of its inquiry mid-December.
