DPF stands for diesel particulate filter. Found solely in diesel cars, they capture and store exhaust soot to keep emissions in check. But their storage capacity is limited, so after some time they need to get rid of soot to free up space. This is achieved through a process called regeneration; this is the key concept in DPF cleaning.
Motorists around Banstead, Carshalton, Sutton and Wallington making long journeys at high speeds - e.g by regularly making use of the motorway - might require DPF cleaning less often than others. This is because the passive regeneration process in-built within the DPF will kick in, burning off soot as they drive. Even just 30 minutes at a decent sustained speed on the motorway can reliably burn off a good amount of soot.
But many motorists only take shorter trips, meaning passive regeneration never has a chance to kick in. This is where active regeneration takes charge. This occurs when your vehicle’s ECU detects your filter reaching a particular storage limit. Extra fuel is then injected to raise exhaust temperature and burn off soot. It achieves similar results to passive regeneration, despite lower speeds or journey times.
For a number of different reasons, both the passive and active regeneration processes might cease to work. This can leave a DPF getting steadily clogged up with no solution in sight. Here’s where drivers around Carshalton, Sutton and Wallington visit Banstead Road Garage. We can run a process called forced regeneration from our workshop, delivering DPF cleaning by manually burning off excess soot, allowing the DPF to start working again.
In many cases, this leads to the DPF’s passive and active regeneration processes also beginning to function again. In other cases, however, you may require further diagnostics to ascertain why your DPF is struggling to function properly. We can get to the bottom of these issues quickly by using sophisticated ECU readers, which retrieve fault codes stored in your engine’s onboard computer. We can then recommend the best course of action, which might be on the spot repairs or adjustments, or DPF replacement in more severe situations.
We recommend motorists in and around the Carshalton, Sutton and Wallington areas visit Banstead Road Garage for DPF cleaning if they encounter any of the following symptoms:
