We just bought an 11 JSW TDI and want to know if there is a link or a thread for information on how the new emissions work on these cars? I know it has an egr cooler and valve, diesel particulate filter, diesel oxidation catalyst, regeneration mode, etc. For example: there is an electric exhaust valve past the DPF that I assume closes to get the regeneration working and increase the exhaust temperature. Does this system use a doser valve igniting the exhaust for the burn like a Caterpillar? I'm just wanting to understand this system better and know some tricks that will help me after the warranty is out.
