Prosecutors in South Korea searched the local office of VW and Audi today, as part of an emissions investigation.

Seoul’s Supreme Prosecutors’ Office sent its investigators to raid the office and the house of an unidentified senior company official according to Reuters, seizing email exchanged with the headquarters and documents on emissions verification.

Volkswagen Korea confirmed the raid without providing any further details, repeating their full cooperation with authorities.

The environmental ministry of South Korea filed a criminal complaint against the local department of VW/Audi and two of their officials, saying that their cars are not compliant with the emission standards.

If found guilty, a conviction could be a prison sentence of up to seven years and a fine of up to 100 million won (around $81,000).

Volkswagen and Audi are among the best-selling imported car brands in South Korea, which is the second biggest Asian market for diesel vehicles after India.
