After getting approval late last year to start fixing its manipulated diesel cars in Europe, Volkswagen is set to push the pedal on recalling 8.5 million compromised vehicles in Europe.

According to Autoweek.com, the embattled automaker will begin recalling the millions of affected vehicles in Europe in groups, whether they require a software update or flow transformer device.

This comes days after VW was granted approval by Germany's Federal Motor Transport Authority to begin emissions fixes on its Amarok 2.0-liter model.

Autoweek reports that the Amarok 2.0-liter Euro 5 diesel was tabbed first in line to receive the fix because its affected engine is found in 5.2 million other models. So, treating the first batch of affected vehicles in Europe, beginning with the Amarok 2.0-liter, will go a long way toward a successful recall — one that is expected to last until the end of this year.

The same website adds that the Passat, which uses the same engine type, would be the next model in line in Europe to receive its emissions fix as part of the recall.

While the recall in Europe has begun, VW is still at a standstill when it comes to emissions-fix plans for the estimated 580,000 affected diesel vehicles in the United States.

Last week, the company's second-largest shareholder slapped the automaker with a three-month deadline to come clean about the roots of its diesel vehicles scandal in hopes of speeding up the recall process in the U.S.

That came after the U.S.'s Environmental Protection Agency (EPA) and California Air Resources Board (CARB) rejected VW's proposed fix for the nearly 600,000 compromised vehicles in the country.

Under the deadline, the automaker would have to report its emissions scandal's origins during the company's annual shareholders meeting, scheduled April 21.

As previously reported, VW could end up buying back its affected vehicles in the U.S.
