Volkswagen’s Fix for the 1.6- and 2.0-liter Diesel Engines (in Europe)

Posted by: Lydia Siu onDecember 4th, 2015


If you have been following my blogs, its surely clear that Volkswagen has been digging themselves a pretty deep hole lately with all of their emission scandals. Well, VW has finally made public details of a fix for its 1.6-liter and 2.0-liter diesel engines in Europe. What the fixes are in Canada and the US is still to be determined due to the vastly different emission standards between the countries. Details for a Canadian and US fix are expected to be announced soon.

Volkswagen announced that all of their 2.0-liter diesel engines will require a simple software update, while the smaller displacement 1.6-liter diesel will require an additional part installed onto the engine as well as an updated software package which will remove the emissions cheating software. The additional part for the 1.6-liter diesel fix is a simple looking plastic component that will be installed ahead of the engine’s air mass sensor. Volkswagen is calling this part a “flow transformer”. As the name suggests, the part is essentially a cylindrical plastic tube with vents inside which will smooth out the flow of air going into the air mass sensor.

Volkswagen explains that “The air mass sensor determines the current air mass throughput, which is a very important parameter for the engine management for an optimum combustion process.” The part should take less than an hour to install, and Volkswagen claims it wont affect current power and fuel efficiency of the 1.6-liter engine.
