The diesel particulate filter filters out soot particles in the exhaust gas. The soot particles are collected in the filter and are burnt off. To assist in this combustion process, Volkswagen recommends that you avoid making only short journeys.
To minimise a blockage of the diesel particulate filter, the engine speed in
vehicles with an automatic gearbox may increase slightly in order to
automatically initiate the cleaning process of the diesel particulate filter.

Even when the exhaust purification system is working perfectly, there may be a smell of sulphur from the exhaust in some conditions. This depends on the sulphur content of the fuel being used.
