Accurate diagnostics, no unnecessary repairs. They told it like it is and didn’t try to upsell anything. That’s rare these days.
Technical inspections have started using equipment that measures the concentration of solid particles in the exhaust gases of diesel vehicles.
If the reading exceeds the established limit - the vehicle does not pass the inspection.
The check applies to diesel and petrol vehicles with the EURO 5 emissions standard and above.
As a rule, these are vehicles registered from around 2013 onward.
Main reasons:
That is why it is important to inspect the entire exhaust system, not just the filter.
Yes. Diagnostics allow us to measure the same parameters that are checked during the technical inspection.
This helps determine:
Signs may include:
Yes. Even if there are no warning messages, the particulate filter may still be operating incorrectly.
An inspection helps determine the system's condition in advance and avoid problems during the technical inspection.

These guys really know what they’re doing. They found the issue that other service centers couldn’t identify.
I came in with a DPF error and thought I’d need to replace the filter. After diagnostics, it turned out the issue was a sensor. They saved me money.
Decent service. No upselling or tricks — they explained everything clearly, showed the issues, and provided a solution.
You can tell right away that they’re professionals. They don’t guess—they check. After the diagnosis, it became clear what the problem was and why.
Diagnostics + a printout of parameters and a clear understanding of what needs to be repaired.
The diesel particulate filter (DPF) is responsible for trapping particulate matter in the exhaust and directly affects passing the vehicle inspection.
We carry out comprehensive DPF diagnostics: checking soot and ash levels, differential pressure, sensor performance, and the correctness of the regeneration process.
Depending on the filter’s condition, we perform cleaning, restoration, or replacement.
It is important to understand that the filter rarely fails on its own, so we also analyze the systems that affect its operation in parallel.
The EGR system is responsible for recirculating exhaust gases and directly affects soot formation.
We diagnose the condition of the EGR valve, cooler, and system channels.
We check for coking, correct opening/closing, and the operation of the control electronics.
A faulty EGR often causes increased soot, unstable engine performance, and issues with the DPF.
The AdBlue (SCR) system reduces nitrogen oxide emissions and is part of the vehicle’s environmental system.
We check the AdBlue pump, injection nozzle, NOx sensors, and the operation of the control system.
Diagnostics allow us to identify dosing errors, sensor malfunctions, and injection system failures.
Incorrect SCR operation can lead to dashboard warnings, power limitations, and issues during vehicle inspection.
The boost system directly affects soot formation and engine performance.
We check boost pressure, turbine geometry, the presence of air leaks, and the overall condition of the system.
A faulty turbocharger can cause power loss, increased fuel consumption, and higher soot production.
It is one of the common causes of DPF problems.
he performance of the fuel system determines fuel combustion quality and the level of soot formation.
We diagnose injectors, the high-pressure fuel pump, and fuel pressure.
We check spray pattern, overflow, operational stability, and parameter compliance.
Even minor deviations in injector performance can significantly increase the load on the DPF.
Sensors are key components that the control system relies on to make decisions.
We check pressure sensors, temperature sensors (EGT), NOx sensors, and other elements.
We analyze their readings, proper operation, and compliance with actual parameters.
A faulty sensor can provide false data, disrupt regeneration, and lead to DPF errors.
Regeneration is the process of cleaning the diesel particulate filter from accumulated soot.
We check how often regeneration is triggered, whether it occurs correctly, and if the required temperatures are reached.
We analyze regeneration conditions, sensor performance, and the control system operation.
Faulty regeneration is one of the main reasons the filter quickly clogs and fails.
