What is exhaust regeneration?
Regeneration is the process of burning off (oxidizing) the accumulated soot from the filter. This is done either passively (from the engine’s exhaust heat in normal operation or by adding a catalyst to the filter) or actively introducing very high heat into the exhaust system.
Does Passat have DPF?
Cleaning your DPF Do not switch off the engine. Take immediate action by driving your vehicle for approximately 25-30 minutes to assist with regeneration. For driving under higher engine load (2,500 – 3,000rpm), utilising the Tiptronic function of the gearbox is recommended.
What is DPF soot mass?
Accumulated Soot Mass: Specifically, the amount of soot built up in the DPF at the time of regeneration, as well as the ash concentration in the soot.
How do I force a DPF regeneration VW?
Drive the vehicle for approx 15 minutes keeping the engine revs between 2000 – 2500 rpm. For automatic vehicles use the ‘S’ setting in order to keep the revs up. If the light doesn’t go off consult your Volkswagen Retailer. Don’t continue to drive as there is a risk of fire!
How do you force a regeneration DPF?
When a DPF reaches a pre- determined particulate matter (PM) fill level (around 40%), the ECU will activate the regeneration process, which can inject up to eight times more fuel per stroke – a rate which is needed to produce temperatures in excess of 550°C dry or 450°C with the passive system (fuel additive Eolys), so …
What year did VW start using DPF?
Every diesel Volkswagen model since 2009 comes equipped with a Diesel Particulate Filter (DPF).
How long does a VW DPF last?
A DPF can last up to around 100,000 miles if maintained properly. After the car has exceeded that mileage, you could be looking at paying a large amount of money for a replacement – so always properly check MoT and service records when buying a used car.
How do I reduce soot on my DPF?
Active regeneration: This is a process that your car can initiate in response to a blockage. Your car injects diesel on the exhaust stroke so that it ignites and burns the soot. Forced regeneration: Mechanics can carry out a forced regeneration where they burn the soot off for you.
