There isn’t much room for error when it comes to compressed natural gas-powered vehicles, especially when it comes to their fuel system, so Volkswagen isn’t taking any risks.

While the cheating emissions scandal is still far from over, the group also has to deal with almost 30,000 vehicles powered by compressed-natural gas in Europe, which will have to get their tanks replaced.

Citing the automaker, Reuters states that the action comes after the brand’s technicians were not able to do the regular check-ups of the gas tanks for corrosion in certain European countries, without naming them, and covers certain units of the 2006-2010 Passat, Touran and Caddy.

Owners of these models will be contacted the Volkswagen and they will have to schedule an appointment with a local authorized dealer for repairs, which will be performed at the expense of the German company.

Further details of the recall remain unknown at this point, but the car manufacturer had already recalled some Touran minivans in July for a similar reason.
