DPF in St Albans | Covering All Aspects of Diesel Particulate Filter Work

M Wilson Motor Repairs provides a complete range of DPF services for motorists in St Albans, Hatfield and the surrounding Hertfordshire areas. Be it DPF cleaning, DPF regen or a turbo clean, our team covers every aspect of keeping your diesel particulate filter operating at optimal levels. Established in 1979, we have over 40 years of specialist experience, so we have the expertise to work with motorists of any kind, from private domestic to commercial fleets.

Diesel particulate filters have been a fixture of diesel-fuel vehicles for two decades. These filters capture and store exhaust soot in order to reduce the emissions produced by your vehicle. However, a DPF only has a finite capacity so, in order to successfully regenerate, this soot must be emptied or ‘burned off’.

Without this effective maintenance, your DPF can become inefficient and eventually impact negatively on the engine and its performance.

Below, we have taken a closer look at the important points involved in DPF cleaning, DPF regen and turbo clean services.

DPF Regeneration

The key to understanding DPF cleaning lays in the process of DPF regen. Diesel particulate filters regenerate in two ways:

Passive Regeneration – This occurs when a car runs at speed on a long stretch of motorway or A-road. These journeys allow the exhaust temperature to rise to the required level for burning off excess soot in the DPF.

As such, we strongly advise diesel-fuel car owners in St Albans, Hatfield and the surrounding areas to drive regularly at sustained speeds for at least 30 to 50 minutes, thus creating the ideal conditions for passive DPF regen.

Active Regeneration – Not everyone undertakes the long, regular journeys at sustained speed for passive DPF regen. In these cases, active regeneration occurs. This involves the automatic injection of extra fuel when a DPF reaches a predetermined limit, usually around 45%. By raising the temperature of the exhaust, DPF cleaning can take place, i.e. burning off the stored soot.

However, if the journey being undertaken is too short, the DPF regen process may not reach a full conclusion. In these cases, the diesel particulate filter remains partially blocked and the warning light continues to illuminate.

DPF Cleaning and Turbo Clean Services

Inadequate DPF regen remains the leading cause of issues related to diesel particulate filters. At M Wilson Motor Repairs, we provide our customers in St Albans, Hatfield and the neighbouring areas with trusted solutions.

We use Forté products and equipment to ensure results in line with industry-leading standards. This includes use of the Power Clean, a 4-in-1 cleaning machine renowned for its exceptional quality. As an added benefit, we do not need to remove any parts or components in order to produce these outstanding results.

The four aspects of cleaning include:

1. Diesel Turbo Clean – This treatment cleans the variable geometry vanes and turbine of diesel turbochargers. Without the need for dismantling, we perform each turbo clean by injecting the treatment directly into the combustion chamber, producing immediate and effective results.

2. Fuel Injection – The highly concentrated cleaning solution cleans the fuel injectors, combustion chamber and intake valves without the need for any form of dismantling or removal.

3. Air Intake – By using a specially designed tool, we inject the cleaner directly into the air-intake, removing contamination from the inlet valves and inlet manifold without having to dismantle.

4. DPF – A highly effective form of DPF cleaning, this solution cleans and flushes out ash, soot and various other contaminants from blocked diesel particulate filters. This restores the original operation without having to remove the DPF from the vehicle.
