Welcome to RAF Turbo DPF
We regenerate turbochargers, DPF filters, injectors and injection pumps. We also do car mechanics — timing belt, oil and filter changes, brake and suspension repairs — and computer diagnostics.
Over twenty years of practice in Zawiercie
RAF Turbo DPF is a workshop run by Rafał Markiewicz in Zawiercie. Over more than twenty years, thousands of parts from cars, vans and trucks, as well as construction and farm machinery, have passed through our benches.
Every job starts with a measurement and an honest assessment of whether a repair makes sense. After the repair we run a control measurement, document the result on a printout and give a written warranty on the work.

Turbocharger regeneration
Every type, from car turbos to truck and machinery units. We strip the turbocharger, check the shaft and bearings, replace the seals and worn parts, and balance the core. Measured before and after the repair, with a printout of the results.
What we do
- Teardown and wear assessment of the shaft, bearings and housings
- New bearings, seals and rings
- Dynamic balancing of the core
- Variable geometry and actuators — cleaning, adjustment and replacement
- Final measurement and a printout of the results
When to bring a turbocharger in
- Loss of power and slower acceleration
- Bluish or black smoke from the exhaust
- Whistling, howling or metallic noises while running
- Rising oil consumption
- Limp mode and boost pressure fault codes
Cars, vans and trucks, construction and farm machinery. Not sure the turbocharger is at fault? We check it before taking the job on and tell you plainly whether a repair makes sense.

We flush soot, ash and oil out of a clogged filter instead of cutting it out or selling you a new one. Flow is measured before and after cleaning, and you get the result on a printout.
What we do
- Flow and resistance measured before and after cleaning
- Wet washing and ultrasonic cleaning
- Soot, ash and oil flushed out of the core
- Printout of the results and a written warranty
When to bring the filter in
- The DPF or engine warning light is on
- The car goes into limp mode and loses power
- Regeneration never finishes or keeps being interrupted
- Fuel use is rising and the oil level keeps climbing
- Differential pressure or clogged-filter fault codes
DPF and FAP filters for cars, vans, trucks and machinery. Not sure the filter is at fault? We check whether it is the core, a sensor or something else. If cleaning would not help, we tell you plainly.

Diesel and petrol injectors as well as injection pumps. Every part is tested separately on the rig — fuel delivery, back-leakage and sealing. Worn parts are replaced with new ones and delivery is set up again. You get a printout of the results.
What we do
- Bench test — before the repair and after it
- Teardown, ultrasonic cleaning and wear measurement
- New nozzles, pumping elements, seals and washers
- Delivery set up and new correction codes for the ECU
When to bring injectors or a pump in
- The engine struggles to start, especially cold
- Uneven running at idle
- Smoke from the exhaust and higher fuel use
- Knocking, hesitation, loss of power
- Engine light on, back-leakage or fuel pressure fault codes
Bosch, Delphi, Denso, Siemens (VDO), Continental. Common Rail, unit injectors, petrol direct injection, inline and rotary pumps. Not sure what is failing? We test the whole set and tell you what can be repaired and what needs replacing.
Call us and describe the symptoms
Computer diagnostics
Before you replace or repair anything, we find out what is really causing the problem. We connect to the ECU, read fault codes and live data, and measure the part — only then do we quote a price.
ECU fault code readout
A full readout of fault codes from the engine and auxiliary control units, with an explanation of what each one means.
Live data
Boost pressure, fuel pressure, injector corrections and sensor data read while the engine is running.
Particulate filter system
Differential pressure, clogging level and regeneration history — whether the filter, a sensor or the control is at fault.
Boost and fuel system
Pressure and flow measurement, a check of actuators and valves, and a search for leaks.
Report before the repair
You get a description of the faults found and a quote. If a repair would not make sense, we tell you plainly.
Car workshop
Besides regenerating parts we run an ordinary workshop: we repair and service cars, and fit the regenerated parts on the spot. One place from diagnosis to pick-up.
- Oil and filter changes, scheduled servicing
- Brakes, suspension and steering
- Timing belt or chain, clutch and dual-mass flywheel replacement
- Exhaust and cooling systems
- Fitting turbochargers, injectors, injection pumps and DPF filters
- Repairs that follow from computer diagnostics

How it works
From the first call to picking the part up.
- 1
You call or drive over
Call us and describe what the car is doing, or visit the workshop during opening hours.
- 2
We check it and quote
We measure flow, clearances and the state of the core, then tell you what it will cost. If a repair makes no sense, we say so plainly — and we do not charge for the check.
- 3
We repair it
Cleaning, or a full teardown with worn parts replaced. Seals, bearings and nozzles are always new, never salvaged.
- 4
You collect it
Control measurement, a printout with before and after figures, and refitting if you want it. The part comes back with a written warranty.
Why repair instead of buying new
A fraction of the price of a new part
A repair costs far less than a new filter, turbo, pump or set of injectors. And the part works as it should afterwards.
No cutting out, no modifications
A DPF cut out means losing type approval and failing inspection. We clean the filter so the car stays within its emission standard.
Measurements, not promises
We measure every part before the repair and after it. You get a printout with numbers, not a promise that it should be fine.
Warranty in writing
Every repair comes with a warranty document. Claims are handled here, not passed on to a manufacturer.
Common questions
How long does it take?
Usually 24 to 48 hours from the day the part reaches us. If you leave the whole car with us, add removal and refitting on top. Urgent jobs can be arranged by phone.
Can every filter be saved?
No. A cracked, melted or burnt-through core is only fit for replacement. We see this during the check and tell you before any work starts.
Do I have to remove the part myself?
No. You can bring the whole car in and we will remove and refit the part here. If the part is already removed, bring it to the workshop.
How do I know the injectors or the pump are failing?
The engine is hard to start when cold, runs unevenly at idle, smokes or uses more fuel. Only a bench test settles it — we test the whole set and tell you which part needs work.
Do fault codes need clearing afterwards?
Yes, and we do it. After refitting we reset the adaptations and the ash counter, and force a regeneration if needed. It is included in the price.
Do I need an appointment?
No. You can visit during opening hours. Calling ahead only helps in that we can tell you straight away whether to bring the part with you.
Do you work with workshops and fleets?
Yes. Workshops and fleet operators get served first, with one consolidated invoice and fixed pricing. Terms are agreed here at the workshop.
Do you repair parts off construction and farm machinery?
Yes. Turbochargers, injectors and injection pumps off tractors, excavators, loaders or forklifts are handled exactly like those off cars. The machine does not have to come in — just bring the part in already removed.
