Noise, fuel consumption concerns force stop
Volkswagen is working to recall and fixed diesel models in Europe, but the recall of Passats with a 2.0-liter turbodiesel engine has been temporarily halted. According to Automotive News Europe, VW stopped fixing those engines while it determined whether the software fix would adversely affect the engines’ performance.
Though Volkswagen officials downplayed the accusations to Automotive News Europe, the reports suggest that modifications to make the 2.0-liter turbodiesel engines meet emissions laws in Europe result in higher fuel consumption and increased noise. The engines must be recalled because they are among the many VW diesels that had “cheating” software that produced more emissions than permitted by law.
“We have to guarantee that noise and especially CO2 emissions are exactly the same as before the fix,” a Volkswagen spokesman told Automotive News Europe.
In Europe, Volkswagen plans to fix 2.0- and 1.2-liter diesel engines by installing new software, which reportedly takes about 30 minutes per car. Certain 1.2-liter diesels in Europe will require a new air-intake component as well as the software fix.
A timeline for a diesel recall in the U.S. is still far from clear; last month, Volkswagen’s Herbert Diess told reporters that the company has, “good chances to achieve an agreement with the authorities in the United States in the next months.”
