DPF cleaning across Preston

Is it really the DPF, or something else? Every Preston visit begins with the fault codes plus the filter's soot and pressure readings, so you find out before any cleaning happens. A mobile clean is £275 + VAT, and that includes us coming to your home or workplace.

Readings we take before cleaning in Preston

The full picture first

We read the codes and record how much soot is in the filter and the pressure across it.

A clear answer

If soot is the cause, we go ahead. If the figures suggest ash, damage or another fault, we explain that and stop there.

Clean with the filter fitted

Our cleaning solution softens the deposits before a forced regeneration clears them.

Proof on the screen

We clear the codes and repeat the readings so you can see the result.

Why DPFs keep blocking

These are the usual reasons a cleaned filter fills up again.

Journeys that end too soon

Regenerations need time at temperature, which short trips rarely give the filter.

A sensor giving false readings

A failing differential pressure sensor confuses the ECU about how full the filter really is.

Excess soot from the engine

Problems with the EGR valve or injectors can push out more soot than the filter can cope with.

Regenerations interrupted

Turning the engine off part way through a regeneration leaves soot behind, and it builds up over time.

Vans and work vehicles in Preston

Vans spending the day on short, stop-start runs give their DPF a hard time, because the exhaust rarely stays hot for long enough. We can clean them at your yard or depot in Preston, fitting in around the working day, and handle several vans on one visit where possible.

Businesses with ongoing DPF work can register for a trade account.

Frequently asked questions about DPF cleaning in Preston

How can you be sure it's the DPF?

The same symptoms can come from other faults, so we check the soot load and pressure readings to confirm the filter is the cause.

Can you tell if the filter is full of ash?

The readings give a good indication. Ash can't be burnt off, so if that's the problem you'll hear before we start.

Can I have the DPF removed instead?

A DPF delete is available from us for off-road and export vehicles only. UK law doesn't allow a road vehicle to run with its DPF removed or switched off, and MOT testers check for this. Read Is DPF removal legal? for the full picture.

What happens if I ignore the DPF light?

The filter keeps filling until the engine drops into limp mode, and it may become too blocked to clean, leaving a new DPF as the only road-legal option.
