Our DPF cleaning process.

A clear, professional workflow from the moment you book to the moment the DPF goes back on the car or back to your workshop.

01

Book in

Call or message us with your registration and symptoms. We confirm the right service, price and slot.

02

Inspect

We check the DPF condition, fault codes and back-pressure. If the filter is physically damaged, we'll tell you straight.

03

On-car chemical clean

For early blockages, a deep chemical flush and force regen without removing the DPF — same day in most cases.

04

Off-car MET Clean

The DPF is removed and cleaned on our MET Clean machine. Hot water and targeted chemicals clear soot and ash the right way.

05

Verify

We inspect and verify the cleaned DPF before refitting, so the result is measurable — not guessed.

06

Return

Refit, reset and force regen if needed. Trade DPFs are packaged and sent back, usually within 24–48 hours.

DPF cleaning on the MET Clean machine.

This is the off-car process in our Derby workshop: the DPF is loaded into the MET Clean machine, flushed with hot water and targeted chemicals, and then inspected before it goes back to the vehicle or back to a trade customer.

  • No guesswork — visual verification
  • Safe for the substrate
  • Same-day or 24–48 hour turnaround
