MUNICH — Volkswagen announced its plans for bringing its line of EA 189 diesel engines into compliance with European regulations. The EA 189 engines are the automaker’s 1.6- and 2.0-liter diesel engines that are a major part of the Dieselgate emissions scandal involving close to 11 million vehicles worldwide.

The plan was detailed in a video and has been approved by German regulators. U.S. emissions regulations are stricter and U.S. regulators have not yet approved a plan to bring the wayward vehicles into compliance.

The program as outlined in the video is comprised of two steps: 1.) an engine control software update and 2.) the installation of a “flow transformer,” essentially a plastic tube with a grate, over the car’s mass air sensor housing assembly, which regulates the car’s fuel injection. The sensor measures how much air is moving through the intake manifold at any given moment and adjusts the amount of fuel being injected into the cylinders accordingly.

The flow transformer, according to Volkswagen, will stabilize the airflow before it hits the sensor.

The hardware and software update will take technicians roughly one hour per vehicle.

The Wolfsburg-based automaker’s 3.0-liter six-cylinder engines will only require a software update to comply with European emissions regulations, it said.
