DPF Cleaning In Carshalton
Diesel particulate filters play a vital role in reducing harmful emissions from diesel vehicles, capturing soot particles before they enter the atmosphere.
However, these filters can become clogged during normal use, particularly in vehicles used primarily for short journeys.
Banstead Road Garage offers professional DPF cleaning in Carshalton, using forced regeneration techniques to restore filter function and prevent costly replacement.
We can identify DPF problems quickly, whilst our regeneration procedures effectively remove accumulated soot to restore proper filter operation and resolve dashboard warning lights.
Understanding DPF Function
Diesel particulate filters work by trapping soot particles in a ceramic honeycomb structure, gradually filling with deposits during normal driving.
The filter cleans itself through a process called regeneration, where excess fuel raises exhaust temperatures high enough to burn off accumulated soot.
Passive Regeneration
During sustained high-speed driving, exhaust temperatures naturally reach levels sufficient to burn off soot deposits automatically.
This passive regeneration typically occurs during motorway journeys lasting 30 minutes or more, keeping the filter clean without driver intervention.
Active Regeneration
When passive regeneration cannot occur due to driving patterns, the vehicle's engine management computer initiates active regeneration by injecting extra fuel to raise exhaust temperatures. This process usually happens every 300-500 miles, depending on driving conditions and soot accumulation rates.
Warning Light Indicators
The first sign of DPF problems usually appears as a dashboard warning light, indicating that the filter has reached its maximum soot capacity. Ignoring this warning can lead to reduced engine power, increased fuel consumption, and eventually complete filter blockage requiring expensive replacement.
Performance Symptoms
Beyond dashboard warnings, DPF problems often manifest as reduced acceleration, poor fuel economy, unusual exhaust smoke, or difficulty starting the engine. These symptoms indicate that the filter is significantly blocked and requires professional attention.
DPF Regeneration Service
Our car garage in Carshalton performs forced regeneration procedures that manually burn off accumulated soot when natural processes fail. This service effectively restores filter function whilst avoiding the high cost of DPF replacement.
