Why you need DPF restoration
The full cycle, turnkey
We do not do «just a wash». DPF restoration with us is a complete cycle: in-depth diagnostics, cleaning or full refurbishment of the filter, related systems checked, ECU adaptation and a verification particle test. You bring in a car with a problem – you drive away with a working filter and a measurement report.
Deep diagnostics instead of guesswork
We examine the filter's condition thoroughly by its parameters: differential pressure, soot and ash mass, regeneration history. In parallel we check the injectors, EGR, turbo and sensors. The problem is not always the filter itself – sometimes cleaning is enough, sometimes deep refurbishment is needed. Diagnostics shows precisely what your car needs.
Full refurbishment – no need to replace the filter
When cleaning is not enough, we perform a full refurbishment: the internal filter element of the DPF is replaced with a new one right inside the original housing, keeping all factory flanges, sensors and mounts. The filter works like new again – at a fraction of the cost of a new DPF at €1,500–4,000.
3-year warranty
We give a 3-year warranty on the work performed and on passing the particle number test at the CSDD roadworthiness inspection. We can afford it because we do the full cycle: fix the cause, restore the filter and prove the result on inspection-grade equipment.
Confidence at the inspection
Since 2026 the inspection in Latvia measures the particle number in diesel exhaust. After our restoration the filter physically works and passes the test with a margin – legally, with no removal and no risks. You drive to CSDD with peace of mind.
The DPF restoration process
Deep diagnostics of the filter and related systems
We connect Launch X431: fault codes, differential pressure, soot and ash mass, temperatures, regeneration history. We check the injectors, EGR, turbo, pressure and temperature sensors – everything that affects how the particulate filter works. A particle measurement on Capelec CAP / TEXA OPABOX records the baseline.
The decision – together with you
Based on the diagnostics we show you the real picture in numbers and propose the optimal path: regeneration, cleaning or full refurbishment. You always understand what is being done to your car and why – no unnecessary work.
Cleaning: regeneration or washing
With moderate soot loading – forced regeneration with a cleaning agent, no removal: the soot burns off at 600–700°C on the car. If ash has built up – hydrodynamic cleaning of the removed filter in the King CAR DPF Washing Machine: ash and soot are flushed out of every channel and the filter regains its factory flow capacity.
Full refurbishment with a new filter element
When cleaning is not enough, we rebuild the filter: the internal filter element is replaced inside the original housing, matched to your specific car. The housing is professionally welded and leak-tested; sensors and pressure lines are replaced if needed. All factory mounts and fittings are preserved.
ECU adaptation, verification test and warranty
We reset the ash and soot counters, adaptations and regeneration intervals. A verification particle and back-pressure measurement on Capelec/TEXA, then a road test with a monitored regeneration. You receive a before/after report and a 3-year warranty on the work and on passing the inspection.
What you get
The filter works like new
flow capacity and back pressure within factory spec
Everything checked end to end
injectors, EGR, turbo and sensors – the cause fixed, the filter will not clog again
3-year warranty
on the work performed and on passing the particle test at the inspection
Confidence at the CSDD inspection – a before/after measurement report in hand
Savings versus filter replacement
the full cycle costs a fraction of a new DPF at €1,500–4,000
What we work with
Launch X431
Diagnostic system for reading fault codes and live DPF parameters: differential pressure, soot and ash mass, temperatures. Starts forced regeneration and resets ash counters and adaptations after restoration.
King CAR DPF Washing Machine
Professional hydrodynamic cleaning station for diesel particulate filters and catalytic converters. Delivers specialised chemistry under controlled pressure and flushes out the ash that no regeneration can remove.
Capelec CAP / TEXA OPABOX
Instruments for measuring particle number and exhaust smoke opacity – the same type used at the state roadworthiness test. Before/after measurements confirm the result in numbers and back our inspection warranty.
The refurbishment station
Our full DPF refurbishment bay: TIG welding of stainless steel, heat-resistant mounting materials and new filter elements matched by size and specification to the specific filter.
Sound familiar?
The DPF or Check Engine light is on and regeneration will not start or never completes
The filter has already been washed or burned out, but everything came back a few weeks later
You were told that only a filter replacement for thousands of euros will help
The car has gone into limp mode – limited power and revs
The CSDD inspection with its particle test is coming up and the DPF is a worry
You have been offered a DPF delete but want a legal solution with a warranty
Frequently asked questions
It is a complete rebuild of the filter with the internal filter element replaced by a new one – right inside the original housing, keeping all factory flanges, sensors and mounts. After refurbishment the filter works like new, at a fraction of the cost of replacing the whole unit. This saves even filters that other workshops sentence to «replacement only».
Cleaning is a single operation: the filter is washed and refitted. Restoration with us is the full cycle: deep diagnostics of the filter and related systems, cleaning or full refurbishment depending on the filter's condition, an ash counter reset with ECU adaptation, and a verification particle test. That is why we give a 3-year warranty, not 3 months.
Based on deep diagnostics, and the decision is made together with you. Soot-loaded filter – regeneration is enough. Ash build-up – hydrodynamic cleaning. Cleaning will not bring back factory parameters – full refurbishment with a new filter element. You see the numbers and understand yourself why this option was chosen.
3 years on the work performed and on passing the particle number test at the CSDD roadworthiness inspection. It is possible because we do the full cycle: we check and sort out everything that affects the filter's operation, restore the filter itself and prove the result on inspection-grade equipment with a before/after report.
With moderate soot loading – yes: forced regeneration with a cleaning agent via Launch X431 burns the soot off at 600–700°C on the car, no dismantling. If ash has built up or refurbishment is needed, the filter is removed and refitted in the same visit. Diagnostics will show precisely what your car needs.
The problem is not always the filter itself: its operation depends on the injectors, EGR, turbo, sensors and driving pattern. That is why we check everything end to end and sort out the cause, not just the consequence. After the full cycle the filter runs normally – that is the basis of our 3-year warranty.
Yes – and we back it with a 3-year warranty. Since 2026 the inspection in Latvia measures the particle number in diesel exhaust. After restoration we check this figure on Capelec CAP / TEXA OPABOX – the same class of equipment used at CSDD stations – so you see the result before your inspection.
DPF restoration with a 3-year warranty at JVK PRO in Riga costs from €550 including VAT. It depends on the filter's condition and the scope of work: regeneration without removal, cleaning with removal, or full refurbishment with a new filter element. In any case it is a fraction of the price of a new filter at €1,500–4,000. We will quote precisely after diagnostics: enter your plate above or call us.
