Mobile DPF Cleaning and Regeneration, At Your Door

The usual signs are the DPF or engine management light, a loss of power or limp mode, regenerations that fail or keep repeating, the cooling fan running often, more smoke than usual and worse fuel economy. The diagnostics confirm it: the fault codes and the pressure readings across the filter show how restricted it is.

A typical DPF cleaning appointment takes about 45 minutes to an hour on site, depending on the vehicle and what the diagnostics find. You get the readings before and after, and a plain explanation of what caused the blockage.

Yes. Our high-pressure chemical clean is done with the filter on the vehicle, where it is parked: your drive, your street or your work car park. No trip to a garage and no days without the car.

The diagnostics before the clean (fault codes, pressure and sensor readings), the high-pressure chemical clean, the recheck of the DPF system afterwards and a plain explanation of what caused the blockage. £195 is the starting price; the exact price depends on the vehicle, the work and where you are.

Yes. If you only want to know whether the DPF is cracked or can be saved, we come out and do just the diagnostics, from £85 depending on where you are. If you then go ahead with the clean, you pay the clean's price only (from £195, or from £225 in Manchester), not the diagnostics on top.

Usually, yes. Limp mode is how the engine protects itself when the soot load gets too high. We had a Mercedes Sprinter in St Helens at 120% soot load and in limp mode: we cleaned the filter on site and found the two failed temperature sensors that had caused it.

They do different jobs. A forced regeneration raises the exhaust temperature to burn off soot and can be enough on a lightly loaded filter. A professional clean removes the built-up soot and ash that a regeneration cannot shift. The readings tell us which one your vehicle needs.

Not if the cause is dealt with. A filter blocks again when something keeps loading it with soot: a failed pressure or temperature sensor, or driving that never lets it regenerate. That is why every clean starts with diagnostics, and why we tell you what else needs attention.

Not every one. Where the filter is suitable, cleaning is an alternative to replacing it. A filter that is cracked, melted or soaked in oil or coolant cannot be saved by cleaning, and the diagnostics show that before any work starts.

A new diesel particulate filter usually costs far more than a clean, which starts from £195. Where the filter is suitable for cleaning, the clean is the alternative to replacing the whole DPF, and the diagnostics tell you which applies before you spend anything.

Yes. Vans block their filters for the same reasons cars do, often worse on stop-start work. One of our write-ups is a Mercedes Sprinter cleaned on site in St Helens after two failed temperature sensors put it into limp mode.
