DPF problems
Check soot loading, differential pressure, exhaust temperatures, regeneration history, sensor plausibility and the engine faults that may have caused the blockage.

Warning lights and limp mode are symptoms, not a diagnosis. We start by finding out why the system is unhappy, checking the components and data that control it before recommending repair, cleaning or software work.
EGR problems
Assess valve operation, requested and actual flow, air-mass readings, cooler condition and related intake or boost faults before deciding what work is needed.
View EGR diagnosticsAdBlue / SCR problems
Test NOx sensors, dosing performance, pump pressure, heater circuits, fluid quality and control-unit faults that can trigger warnings or countdowns.

Removal services
Supported software removal options
Where removal is the chosen route, the calibration must deal with the complete system rather than simply hiding a warning light. Support is checked against this exact ECU and powertrain before work is booked.
DPF removal
Calibration changes matched to the DPF hardware work, with related regeneration and fault strategies handled correctly.
EGR removal
Software changes for supported EGR systems, reviewed alongside airflow, boost and engine-condition data.
AdBlue / SCR removal
Supported SCR-system calibration covering dosing, NOx monitoring and associated warning or countdown strategies.
