Volkswagen Polo Owners Manual: Diesel particulate filter
First read and observe the introductory information
and safety warnings
The diesel particulate filter filters out soot particles in the exhaust gas. The soot particles gather in the filter and are burnt under high temperatures periodically (regeneration). Heat produced can warm the engine.
Regeneration can cause noises, light smells and delay in radiator fan irrespective of the outside temperature, even after the engine is switched off.
To assist the regeneration of diesel particle filter, Volkswagen recommends that
you avoid making only short journeys. In vehicles with automatic gearboxes the engine
speed can increase while the vehicle is being driven. However, the indicator lamp
will not light up.
Observe the following points to ensure that the exhaust system and the diesel particulate filter will work properly for a long time:
- Only use diesel with low sulphur levels .
- Never use biodiesel, petrol or heating oil.
- Do not allow the fuel tank to run empty.
- Do not overfill engine oil .
- Do not tow-start the vehicle. Use jump leads .
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.
