DIAGNOSE BEFORE REPAIR
DPF and AdBlue faults are system faults, not just warning lights.
A DPF or AdBlue warning can be caused by the filter itself, but it can also result from sensors, exhaust temperature, differential pressure, engine running conditions, SCR/NOx faults, dosing problems or another underlying engine-management issue. Correct diagnosis helps avoid replacing parts that are not responsible for the fault.
DPF diagnostics in Cork
We diagnose DPF-related faults including failed or repeated regeneration, excessive soot loading, differential-pressure problems, exhaust-temperature sensor faults and engine-management issues that prevent regeneration from completing correctly.
AdBlue & SCR diagnostics
AdBlue/SCR systems use pumps, heaters, injectors, level and quality monitoring, NOx sensors and ECU logic. We diagnose warning messages and fault codes to determine whether the problem is in the dosing system, sensors, wiring, supply, SCR monitoring or another related system.
DPF cleaning, regeneration and repair
Where suitable, a diagnostic regeneration or related repair may be appropriate. A forced regeneration should not be treated as a universal fix: if the vehicle has an underlying fault, that cause needs to be addressed so the problem does not simply return.
