DPF, AdBlue or EGR warning? Find why—not just what lit up.
A blocked filter or countdown may be the result of another fault. We assess pressure, temperature, dosing, actuators and related systems before recommending cleaning or replacement.
Recognise this?
Symptoms that need an answer.
- DPF light or failed regeneration
- AdBlue countdown or no-start warning
- EGR flow fault or limp mode
- NOx or pressure-sensor fault
- Warning returned after previous work
Why Engine Clean
Root cause first
A forced regeneration is not a diagnosis.
The whole system
DPF, EGR, AdBlue, sensors and operating conditions are connected.
Repair from evidence
Clean, repair or replace only when the data supports it.
