A correction to the headline; its only older diesels, not all diesels. From way down the article: > Cars that meet Euro-4 emissions standards could be banned from Stuttgart from next January, while Euro-5 vehicles should not be banned until Sept. 1, 2019, four years after the introduction of the latest Euro-6 standard. If you have a diesel with Ad Blu designed to catalytically remove NOx, you should be OK for now.
