Self Study Program 540 – SCR Exhaust Gas Treatment in the Passat 2015

VAG SSP 540. This Self-study Programme will provide you with information about the new features of the SCR system using the Passat 2015 as an example.

Across the globe, lawmakers and authorities are progressively lowering the limits for nitrogen oxide levels in motor vehicle exhaust gases. One key technology in reducing nitrogen oxide emissions is the “selective catalytic reduction” exhaust gas treatment system (SCR system).

Volkswagen started using this exhaust gas treatment system in cars as early as 2009 with the “Passat BlueTDI”. At the time, this model already fulfilled the strict nitrogen oxide limits set by the EU6 emission standard, which came into force in Europe in September 2014. The SCR system has been enhanced and optimised to adapt the exhaust gas treatment system to the requirements of the new EA288 diesel engine family and to also meet future challenges in reducing emissions.
