DPF in St Albans | Diesel Particulate Filter Services

M Wilson Motor Repairs offers a complete range of DPF services to motorists in St Albans, Hatfield and Hertfordshire. From turbo cleaning and DPF cleaning, to DPF regeneration, we keep diesel particulate filters operating at optimal levels. The DPF is a feature on diesel models and one that has been in use for two decades. The filter captures and stores exhaust soot to reduce emissions. A DPF only has a finite capacity so, to successfully regenerate, it needs to burn this soot off.

Without ongoing maintenance, the DPF becomes inefficient and, eventually, has a negative impact on engines and performance. Below, we take a closer look at the more important elements of DPF cleaning, turbo cleans and DPF regen services.

DPF Regeneration

The key to DPF cleaning sits firmly with the regeneration process. A DPF regenerates in two ways:

Passive Regeneration – DPF regen occurs when cars run at speed on long stretches of motorways or roads. These journeys increase exhaust temperatures to the required levels for soot burning. We advise diesel owners in St Albans and Hatfield to drive at sustained speeds for 30 to 50 minutes, creating ideal conditions for passive DPF regeneration.

Active Regeneration – Short journeys rarely allow for sustained speeds and passive DPF regen. Because of this, active regeneration occurs. This involves the automatic injection of extra fuel when a DPF reaches a predetermined soot limit of around 45%. By raising the temperature of the exhaust, DPF cleaning takes place to burn off soot.

The regeneration process might not reach a full conclusion over a shorter journey, leaving the DPF partially blocked and warning lights illuminated.

DPF Cleaning and Turbo Cleans

Inadequate DPF regeneration is the main cause of diesel particulate filter issues. M Wilson Motor Repairs provides customers in St Albans, Hatfield and Hertfordshire with practical solutions at affordable prices. We use Forté equipment and products to deliver industry-leading results. This includes use of a Power Clean, a 4-in-1 cleaning machine renowned for its performance.

We never need to remove parts to produce outstanding results.

The four aspects of cleaning include:

1. Diesel Turbo Clean – This treatment cleans the variable geometry vanes and turbines of turbochargers. We perform turbo cleans by injecting treatments into combustion chambers for immediate results with no dismantling.

2. Fuel Injection – We use a concentrated cleaning solution to clean fuel injectors, combustion chambers and intake valves without the need for dismantling.

3. Air Intakes – Using a special tool, we inject cleaners directly into air intakes to remove contamination from the inlet valves and manifolds without dismantling.

4. DPF Cleaning – With DPF cleaning, a solution cleans and flushes out ash, soot and other contaminants from blocked diesel particulate filters. This restores original operational performance without having to remove the DPF.

M Wilson Motor Repairs has an extensive range of automotive services available in St Albans and the surrounding areas, including Volvo servicing and car repairs on all popular makes and models, and Class IV MOT testing.
