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:

• DPF damage or wear
• faulty pressure or temperature sensors
• injector problems
• turbocharger malfunction
• incorrect regeneration system operation

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:

• whether the vehicle meets the standards
• whether repairs are needed
• whether the filter is in working condition.

Signs may include:

• a DPF warning on the dashboard
• frequent regeneration cycles
• engine power loss
• increased fuel consumption
• smoke from the exhaust system.

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.
