TÜV Rheinland warns against cheap LPG and CNG conversions

German motorists are eager to convert their cars to run with LPG (Liquified Petroleum Gas) and CNG (Compressed Natural Gas). However, unless your next car purchase comes with the LPG/CNG conversion as standard, you should be careful where you get your car converted, according to TÜV Rheinland. The group issued a note of warning stating that several poorly performed conversions had been detected recently. Aftermarket conversions aren't cheap: LPG conversion costs from €1,500 to €2,500 whereas a CNG conversion can top up to €4,500. Legitimate conversions offer legal certificates when they're completed, and when a "black" conversion is discovered, getting it legalized can cost €1,500. This offsets all potential savings, both in emissions and at the pump.
