On Monday, South Korea’s environment ministry indicted that it is deciding whether it will revoke certification of 32 Volkswagen models following accusations from prosecutors that the company falsified the results of emissions and noise-level tests.

In the statement, the ministry said that retracting the certifications would result in sales being suspended for certain Volkswagen, Audi and Bentley models. Twenty-seven of the affected models are currently available in South Korea.

Volkswagen sales in South Korea have dropped 33 percent to 12,463 units during the first six months of this year, following the German automaker’s admission that it used engine software to manipulate emissions tests for some of its diesel cars.

The decision on certification status is expected to follow a ministry meeting scheduled for July 22.

Update: Beginning July 25, Volkswagen will suspend sales of most models to “reduce confusion among dealers and customers.”
