Volkswagen is recalling the natural gas model series Touran, Passat and Caddy in a voluntary recall in the workshops in Germany. As a precaution, the gas bottles are exchanged for bottles with new paint system.
In Germany, 6,270 models in the recall affected, specifically 2361 VW Touran (model 2011 to 2014), 2359 VW Caddy (2011 to 2012) and 1550 VW Passat (2011 to 2014). After release from Volkswagen, the company wants to "make sure to replace all the gas tanks of the old generation and thus all vehicles be converted to gas cylinders with the current, improved series status."
VW gas tank exchange is free
The CNG underground tanks are exposed to external influences which may lead to a reduction of the durability. Therefore, the gas cylinders must be regularly reviewed in accordance with the Volkswagen service plans. "If the gas system check is not or only insufficiently made can caused by mechanical damage corrosion of the bottles go undetected. This results in a risk that in some of these vehicles a damaged outer shell no longer has the required corrosion protection. With progressive corrosion over a longer period, the wall thickness of a gas tank can be reduced below the necessary residual wall thickness. Gas tanks with too small residual wall thickness may rupture and lead to a substantial risk of injury risk to life and limb, "says Volkswagen on.
Gas station blast: There was something ?!
The conversion of the gas tank is free. Furthermore, VW points out that the clearance certificates from model year 2011 still have their validity uind refueling of natural gas continues to be permitted.
In autumn 2016 VW had called the three models from model years 2005 to 2010 in the workshops. At that time, 5,900 models were affected. The explosion of a VW Touran while refueling at a natural gas filling station had for some time means that VW CNG models not only allowed at numerous filling stations or recharge with clearance certificate.
