Diesel technology has taken a few hits ever since Volkswagen's Dieselgate scandal broke out. Other automakers such as Fiat Chrysler and General Motors are also being investigated for possible emissions fraud on certain models.
As a way to reassure the public about their own diesel technology, Mercedes-Benz recently issued a voluntary recall on more than 3 million diesel vehicles in Europe.
“The public debate about diesel engines is creating uncertainty – especially for our customers. We have therefore decided on additional measures to reassure drivers of diesel cars and to strengthen confidence in diesel technology. We are convinced that diesel engines will continue to be a fixed element of the drive-system mix, not least due to their low CO2 emissions,” said Dr. Zetsche, Chariman of the Board of Management at Daimler AG and Head of Mercedes-Benz Cars.
What this actually means is a preventive measure in making sure that all of their turbo-diesels follow emission laws. Mercedes-Benz will inspect nearly all Euro 5 and Euro 6 compliant cars in close cooperation with the German regulatory authorities. The company is investing EUR 220 million and will not involve any costs to the customers.
The company has not admitted in any wrongdoing and reiterates that this is simply to reassure drivers of diesel cars and to strengthen confidence in diesel technology.
Since March 2017, the automaker has offered its customers that drive compact cars an improvement of nitrogen-oxide (N02) emissions for one engine version. An estimated 45-percent of those cars have already been given an update. Meanwhile, a voluntary service action is also being carried out for V-Class customers, with approximately 75-percent of the vehicles in Germany.
