Machine Process
The removed filter can be cleaned outside the vehicle using a controlled workshop process rather than relying on the car to complete the whole recovery.
Price and limits
Off-car DPF cleaning is £199 for a removed filter.
The £199 price is for the off-car cleaning/refurbishment service on a DPF that has already been removed. It does not include removal, refitting, seized hardware, gaskets, diagnostics or workshop labour unless separately quoted.
£199 Removed-filter clean
A cleaned filter still needs a healthy vehicle around it. If the fault that blocked the DPF is still there, the filter can block again after refitting.
Why choose off-car cleaning
Deeper cleaning when on-car cleaning is not the right route.
Off-car cleaning makes sense when the filter needs deeper cleaning away from the vehicle, when a garage has already removed it, or when on-car cleaning is not suitable because of access, condition or fault evidence.
Inspection Led
The filter is checked for obvious signs of cracking, melting, contamination or missing internal material before expectations are set.
Trade Friendly
Garages can handle diagnosis, removal and refitting while using PPG for the specialist DPF cleaning stage.
The process
Simple, controlled and honest.
A clean filter still needs a healthy vehicle around it, so the repair path does not stop at the machine.
Remove
The DPF is removed by PPG if quoted, or supplied already removed by a trade/customer route.
Inspect
We check for obvious physical damage that cleaning cannot repair.
Clean
The filter goes through the off-car cleaning process where it is suitable.
Refit & Check
After refitting, pressure data, fault codes and regeneration behaviour should be checked.
Soot and ash removal proof
This is why forced regens are not always the answer.
This Citroen Picasso DPF was loaded with soot and ash. Soot can be reduced through regeneration when the vehicle is healthy, but ash is the build-up that will not simply burn away. That is where off-car machine cleaning earns its place, provided the filter substrate is still physically intact.
55g Soot
Recorded before cleaning in this example.
Ash Loading
Ash needs proper off-car cleaning, not repeated forced regens.
Assessment Still Matters
No one should promise a save before checking suitability.
When it makes sense
Use this route when a removed-filter process is more appropriate.
Already Removed
- The vehicle has already had the filter removed by a garage
- A trade customer needs a filter cleaning service
- PPG is handling only the specialist DPF cleaning stage
On-Car Not Suitable
- Access, condition or pressure data suggests on-car cleaning is not right
- The filter needs deeper cleaning away from the vehicle
- Ash loading or contamination concerns need inspection
Clear Exclusions
- Removal and refitting are separate unless quoted
- Gaskets, seized hardware and diagnostics are separate
- Root-cause repair must still be addressed
After refitting
The cleaned filter is only one part of the repair path.
If the fault that blocked it is still there, the filter can block again. After refitting, pressure readings, fault codes and regeneration behaviour should be checked where possible.
Root Cause
EGR, boost, fuelling, sensor and temperature faults should be resolved before the vehicle returns to normal use.
Vehicle Data
After refitting, pressure readings, fault codes and regeneration behaviour should be checked where possible.
Road Use
Cleaning cannot turn a physically damaged or missing substrate into a compliant filter. PPG supports lawful DPF assessment and cleaning.
Before sending a filter
Good information prevents wasted work and repeat failure.
Vehicle Detail
Confirm vehicle details, fault codes and symptoms before removal where possible.
Packaging
Use secure packaging to prevent damage in transit and protect sensors, pipes and exposed ports where applicable.
Repair Path
Address the root cause before the cleaned filter is refitted so the same fault does not return.
FAQs
Off-Car DPF Cleaning FAQs
Is removal and refitting included in the £199?
No. The £199 is for the cleaning/refurbishment service on a removed DPF. Removal, refitting, gaskets, seized hardware, diagnostics and labour are separate unless quoted.
Can off-car cleaning save every DPF?
No. Off-car cleaning is designed to remove soot and ash contamination where the filter substrate is physically intact. It cannot repair melted, cracked, collapsed, missing or chemically contaminated filter material.
Can garages send filters to PPG?
Yes. The service is trade friendly where the garage handles vehicle-side diagnosis, removal and refitting separately.
What should be checked after refitting?
Pressure readings, fault codes, sensor behaviour and regeneration behaviour should be checked where possible. The vehicle fault that caused the blockage must be resolved.
