What is mobile DPF cleaning?
Mobile DPF cleaning is an on-vehicle service where a technician comes to your site, injects a cleaning solution into the DPF via the upstream pressure sensor port, then runs the engine through a managed thermal cycle to flush soot and dry the filter. No DPF removal required.
How the process runs
- Diagnostic scan to read soot/ash load and confirm no underlying mechanical fault.
- Connect injection equipment to the DPF pressure sensor port.
- Inject heated cleaning solution through the DPF.
- Run engine at controlled RPM / load for managed dry cycle.
- Final regen run to verify and reset the ECU soot counter.
When mobile cleaning is the right call
- Fleet sites with multiple vehicles per visit (best per-vehicle value)
- DPF mounted in awkward position (long removal time)
- Driver cannot bring vehicle to workshop (taxi, courier, mobility)
- Soot load between 50-75% with no ash overload
- Vehicle still starts and runs
When workshop cleaning beats mobile
- Filter has 80,000+ miles with no service history (ash overload likely)
- Substrate damage suspected
- Filter cannot pass any exhaust gas (fully blocked)
- Oil contamination (mobile cleaning will not remove oil residue)
What it costs
Mobile DPF cleaning runs £180-£280 per vehicle in the UK. Fleet visits with 5+ vehicles drop to £140-£180 per vehicle. We cover Birmingham, the Midlands, and on request UK-wide for fleet jobs. See our mobile service.
What to have ready before the visit
- Vehicle reg, make, model, year, engine code
- Diagnostic codes if you have them
- Service history (especially last DPF service)
- Safe place to park with engine running for 30-60 minutes
- Battery in good condition (engine runs at varying RPM throughout)
