这个修复会使发动机的排放控制功能运行于更宽的工况。修复前的控制软件只允许排放控制功能运行在极狭窄的范围，功能上来说跟大众的“defeat device”非常类似。据纽约时报报道，此举意在避免像大众一样被罚巨大金额。
区别在于：大众是被监管机构调查清楚认定作弊以后才召回的，戴姆勒则是在监管机构正在调查的时候主动召回。能不能获得较轻的处罚拭目以待。
另外，根据大众召回的经验，这样的修复程序会给发动机带来负面影响。不知道梅奔会不会重蹈覆辙。
By volunteering to upgrade the cars’ emission systems, Daimler appears to be trying to avoid the fate of Volkswagen. The carmaker, based in Wolfsburg, Germany, paid more than $22 billion in civil and criminal penalties and legal settlements in the United States after admitting to manipulating diesel emissions controls. The financial penalties for Volkswagen were much worse than they might have been because it staged an elaborate cover-up after regulators began asking questions in early 2014.
A software update, which Daimler said would take about an hour, will cause the emissions controls to operate under a broader set of conditions. Previously, the pollution equipment was programmed to operate at maximum effectiveness only under a narrow range of temperatures. That range will be expanded.
