We diagnose recurring EGR faults, failed DPF regenerations and AdBlue system failures. We check differential pressure, temperatures, calculated soot and ash load, sensor operation, dosing and the vehicle's driving conditions.

Not every issue is solved by forcing a regeneration. The root cause may be a faulty sensor, leak, thermostat, injector, repeated short journeys or an engine fault producing excessive soot.

Depending on the results, we perform cleaning, controlled regeneration, electrical repair or replacement of the required component. We then verify that values return to normal and the vehicle can complete regeneration cycles correctly.

We recommend a technically sound and legal solution so the vehicle runs properly, keeps its emissions systems operational and can pass inspection.
