DPF Delete vs DPF Cleaning: Which Is Right for You?
Blocked DPF causing limp mode, warning lights, or repeated regens?
This guide compares DPF cleaning and DPF delete so you can choose the right fix for your driving and budget.
When DPF problems start, most drivers hear two options straight away:
clean it or delete it.
The right choice depends on how you drive, the condition of the system, and how often the fault returns.
This page breaks down the real-world differences between DPF cleaning and DPF delete,
without guesswork or scare tactics.
Quick takeaway
- Cleaning suits cars that still do regular motorway runs.
- Delete suits vehicles that repeatedly clog despite cleaning.
- Diagnostics first saves money either way.

What the DPF actually does
The diesel particulate filter traps soot from exhaust gases.
When conditions are right, the car performs a regeneration to burn that soot off.
Short trips and stop-start driving prevent this process from completing.
Over time, incomplete regens lead to blockages, warning lights, limp mode, and rising repair costs.
That is where cleaning or deleting enters the conversation.
DPF cleaning: when it works well
DPF cleaning removes built-up soot and ash so the filter can flow again.
It works best when the underlying cause of blockage is addressed.
Best for
- Cars doing regular motorway journeys.
- First or second blockage.
- No major sensor or EGR faults.
Limitations
- Does not fix repeated short-trip driving.
- Blockages can return.
- Not effective if the DPF substrate is damaged.
If your DPF keeps blocking alongside EGR issues, see:
EGR solutions.
DPF delete: when drivers choose this route
A DPF delete removes the filter’s operation in software and hardware.
It is usually considered when cleaning becomes a repeat expense rather than a fix.
Common reasons drivers choose delete
- Repeated DPF blockages despite cleaning.
- Mainly short journeys or urban driving.
- Work vans losing time to limp mode.
- Rising costs of sensors and forced regens.
