Update in the Daimler emissions scandal – Hundreds of thousands of vans will now be asked for a software update
The fact that the Sprinter, Vito and Viano models are also affected by the emissions scandal has been known since 2019. Now Daimler AG has apparently succeeded in developing the software updates required by the KBA and having them approved by the KBA. As it became known, hundreds of thousands of Daimler drivers can now expect a letter from Daimler AG asking them to subject their vehicles to the update. Daimler is running the measure under the recall code NC3II6515R or NC2II651R.
The vans are equipped with an impermissible defeat device in the form of the coolant setpoint temperature control. This is now apparently to be removed as part of the software update. The coolant setpoint temperature control is software that ensures that the rate of exhaust gas recirculation (EGR) is reduced outside the test conditions (NEDC test cycle) by initially keeping the engine coolant temperature and thus the engine oil temperature low via the electrically switched coolant thermostatic valve. Thus, an EGR map with lower rates is used in real road operation than under test conditions. Lowering the EGR rate leads to increased nitrogen oxide emissions.
According to our current information, the vehicles affected by the recall are from the Sprinter, Vito and Viano series with the Euro 5 emissions standard. These have the OM 651 series engine already known from the emissions scandal and were produced between 2010 and 2018 (Sprinter) or between 2010 and 2014 (Vito, Viano).
Are you the owner of such a Daimler AG van and feel cheated? Regardless of whether you have already received a recall letter or not, we will be happy to advise you.
