Diesel particulate filters

Diesel particulate filters are very expensive. A new one from a car manufacturer can cost £1,000 and £3,500, potentially wiping out the cost savings associated with driving a diesel. As cars age, the cost of the replacement DPF could be more than the value of the car – and it is older, higher mileage cars that are most likely to require a new DPF.It’s a failure to correctly regenerate that is the cause of most diesel particulate filter issues: they become blocked, which increases exhaust emissions, stifles engine performance and sometimes even puts the car into a restricted ‘limp-home mode’.Another way to kill your DPF with oil is via a leaky turbo oil seal. So I would absolutely not be letting those service intervals slide. EGR & GLOW PLUGS. Sticky EGR valves are another DPF killer - pumping excess crankcase vapour into the exhaust. Faulty glow-plugs - also DPF-deadly - because they cause the engine to run too rich on start-up.However, there is already a simple, low cost solution available, which addresses the root cause of these DPF problems. What is required is to clean up the fuel burn, rather than “after treat” it with a diesel particulate filter! Improve the combustion process. Burn away excess soot and carbon. Remove potential DPF Blockages.Ash build-up is the primary reason for premature DPF failure and is the most important factor controlling the service life of the filter. Ash and soot accumulation restricts exhaust flow, therefore increasing back pressure, making it harder for the engine to breathe. This can greatly affect performance and fuel consumption.Petrol particulate filters. Just reading the reviews for the updated Fabia, I see the petrol models are now equipped with a petrol particulate filter, as I think all new petrol cars will have to be, if not now then in the future, does this mean that they will suffer the same problems as the diesel equivalents especially if , like me, you just do low mileage’s,To reduce emissions, diesel cars are fitted with a Diesel Particulate Filter (DPF) – something that filters and catches soot particles. Most DPFs will automatically clear as they’re used but on rare occasions, in specific circumstances, they may get blocked and require manual cleaning. In normal use, a DPF cleans or regenerates itself by .
In a statement from Nissan to watchdog regarding this issue they said, “The 1.5dCi, 1.6dCi and 2.0dCi engines fitted to QASHQAI include a diesel particulate filter (DPF) to reduce emissions and help protect the environment. The functionality of a DPF may not be suitable for all customers.Not many drivers know what a Diesel Particulate Filter (DPF) is – until it costs them serious money. And replacing one can cost £1000 or more. Green Flag attends a lot of cars that have broken down with DPF problems and they are caused by one primary factor: the DPF is clogged with soot because the driver has ignored the warning lamp.By far the biggest cause of DPF regeneration failure is firstly down to how the car is used (repeated short journeys or City Driving) or perhaps the DPF Cycle starting but then the car stopped and the engine turned off before the DPF Regeneration can complete. Often there can be signs of an ‘aborted dpf regeneration cycle”, such as the .
