Recall roundup – VW’s CNG cars for tank issue image

The German automaker has issued a new recall service campaign and this time around involved are the Caddy, Passat and Touran models equipped with natural-gas-powertrains in Europe.

Approximately 30,000 units will be serviced, the ones being equipped with fuel tanks that cannot be properly checked for corrosion. The company said some standard checks aren’t possible in certain countries in the region. The affected models include the Caddy, Passat, and Touran models produced between 2006 and 2010, and powered by a 2.0-liter eight-valve engine running on natural-gas, the ones developing 107 horsepower (80 kilowatts). The owners will be called to a dealership where the tank will be replaced without paying.

This is the second time the Touran with CNG has been recalled – back in July VW also replaced front gas bottles due to corrosion risk and this is while CNG cars are seen as safer than diesel, petrol or propane motors, as methane combustion delivers less harmful gasses. But the gas bottles, usually cylindrical or spherical, have to be kept at high pressure of 20–25 MPa (2,900–3,600 psi) and need to be checked regularly for corrosion. Volkswagen also has a huge issue with the Dieselgate recalls, as it needs to service no less than 8.5 million diesel cars in Europe.
