In modern diesel vehicles, you will often find a catalytic converter as well as a DPF as Portion of the exhaust system to meet stringent emission specifications. The catalytic converter handles the chemical pollutants, while the DPF tackles the particulate matter popular in diesel exhaust.
In any circumstance, Should the DPF gentle keeps approaching, it’s crucial that you choose your automobile to some mechanic and possess them diagnose the trouble.
Speed up moderately in minimal gears while listening for abnormal Appears indicating residual particles or lubrication issues. Top-conclude power need to really feel powerful after superior restriction exhaust backpressure dissipates write-up-cleaning.
A DPF is often a self-cleaning equipment, so In case the DPF is blocked Then you definitely should find The difficulty 1st as an alternative to just cleaning it and obtaining the issue occur again.
The best way to keep up a DPF is to ensure it’s fully able to regenerate itself when it’s stuffed with soot (once the warning mild seems).
Probably the most reliable indicator your diesel particulate filter needs cleaning is if the Verify engine light-weight illuminates, accompanied by DPF warning messages. Typical indicator lights include:
Our colleagues in excess of at Overdrive sister publication CCJ in February took a dive into best tactics of preserving a DPF and extending its existence — approaches you could employ to keep your DPF jogging more time and with stp dpf cleaner less headaches and repairs.
Take into consideration including accepted detergent items to long term fuel tank fill-ups, especially when using reduced-cetane diesel. High quality diesel additives assistance more break down stubborn soot through combustion while keeping injectors and seals conditioned against premature dress in.
The cost of cleaning a DPF can vary commonly, based on the variables stated earlier mentioned. Here are some estimated costs for that average DPF cleaner in Queensland, Australia:
When you haven’t performed any higher-pace driving in the course of this time, the ECU will automatically elevate the temperature with the exhaust system by injecting fuel, allowing for saved soot to become burned from the DPF.
Lots of modern diesel vehicles have a dynamic regeneration system built-in to clean the DPF automatically for the duration of standard operation.
At the time diesel particulate filter cleaning concludes, either DIY or professional, make sure to choose these put up-service precautions:
Taking away the DPF will often induce the warning gentle to glow – which itself is an MOT failure level: no dashboard warning lights should continue being on during the exam.
If there’s a fault Together with the DPF or maybe the differential pressure sensor, which allows your car know the DPF's position, the engine administration mild may additionally appear on.
