How the Master/Trafic AdBlue system works
dCi Blue Masters and Trafics use a heated tank pump, dosing module and NOx sensors. The same hardware appears in Nissan, Fiat Talento and some Vauxhall vans.
Recovery and conversion Masters often have extra wiring near the chassis that is worth checking.
Fault codes we commonly see on the Master/Trafic
- P20EE — SCR efficiency
- P229F — NOx sensor performance
- P20B9 — Heater circuit
What we check on site
The technician confirms the right repair after checking the vehicle. Many faults are fixed on the spot; some need a part ordered. Mobile call-out from £150 minimum. Final cost depends on the vehicle, location, diagnosis and work required.
- Read engine and SCR data, check AdBlue quality reading
- Test pump and heater
- Inspect wiring near the tank for chafe
