The diesel particulate filter (DPF) traps the soot produced when diesel burns. In city driving, where the engine never reaches the temperature needed for regeneration, the filter clogs — causing power loss, limp mode and recurring fault codes.
VoltiMoto handles DPF removal and delete in Tallinn in software: we remove filter monitoring and regeneration from the ECU, so it no longer raises DPF-related faults. We save the original software before every job, so the change can be reversed.

When does DPF removal help?
Typical signs that the particulate filter is clogged and repeated regeneration no longer helps:
- DPF or engine warning light on, with recurring fault codes
- Power loss or limp mode
- Frequent forced regenerations that never complete
- Rising fuel consumption and engine oil diluted with fuel
- A quote for a new original filter running over a thousand euros
DPF cleaning, replacement or delete?
Chemical DPF cleaning can relieve a blockage temporarily, but in city driving the problem usually returns within a few months, because the cause — exhaust temperature that stays too low — is unchanged. Replacing the filter with an original part does solve it, but can cost over a thousand euros.
A software DPF delete removes filter monitoring and regeneration from the ECU, so it no longer raises particulate-filter faults. It is a permanent fix that does not depend on how the car is driven.
If the car also has EGR or AdBlue problems, see our AdBlue, DPF and EGR removal service — several systems together costs less than one at a time.
DPF removal and roadworthiness testing
To say it plainly: removing an emissions system makes the vehicle non-compliant with current emissions requirements, and such a car should not pass a roadworthiness test. Software DPF removal is therefore intended for vehicles not used on public roads — track use or special-purpose machinery, for example.
If the car has to stay road-legal, the right route is diagnosing and repairing the original system. Get in touch and we will help work out what is actually wrong.
How does a DPF delete work?
The whole job is done in the ECU software over a diagnostic cable — usually within one working day.
Call or send an enquiry — tell us the make, model, engine and any fault codes you know.
Diagnostics: we read the ECU fault codes and confirm the problem really is the particulate filter.
We save the original software, write the modified software to the ECU and clear the related fault codes.
Frequently asked questions
What is a DPF delete?
A DPF delete is a change to the ECU software that removes particulate-filter monitoring and regeneration. The ECU then no longer raises DPF-related fault codes or puts the car into limp mode because of them.
What is the difference between DPF cleaning and a DPF delete?
Chemical cleaning removes soot from the filter but does not change the cause: in city driving, where the engine never reaches regeneration temperature, the filter usually clogs again within a few months. A software delete removes filter monitoring and regeneration from the ECU, so it no longer raises particulate-filter faults.
Is particulate filter removal a software or a mechanical job?
Our service is software-based — we change the ECU software so that system monitoring and the related fault codes go away. Mechanical work is a separate matter, which we always discuss for the specific car before booking.
How much does DPF removal cost?
Electronic removal is listed at 200–350 €. The exact price depends on the ECU type and how many systems are switched off at once — see the full price list or ask for a free quote and we will reply the same working day.
How long does a DPF delete take?
Most jobs are done within one working day, usually in 1–3 hours. We confirm the exact time after diagnostics, because reading and writing ECUs differs between models.
Can the change be reversed later?
Yes. We save the original software before every job, so the original configuration can be restored. Software work carries a lifetime warranty.
Will the car pass a roadworthiness test after DPF removal?
No. Removing an emissions system makes the vehicle non-compliant with current emissions requirements, and such a car should not pass a roadworthiness test. Software removal is intended for vehicles not used on public roads.
