Renault Trafic AdBlue Problems — Diagnosed & Fixed
Van · 1.6 dCi (Euro 6) · 2.0 Blue dCi
The Renault Trafic shares its platform with the Vauxhall Vivaro. AdBlue faults — particularly on the 1.6 dCi twin-turbo — cluster around NOx sensor failure and dosing module crystallisation.
Trafic drivers commonly see an anti-pollution warning, AdBlue light and 'start-up not possible' countdown. Don't ignore the countdown — lockout follows.

Common causes on the Trafic
Downstream NOx sensor failure
Trafic NOx sensors are a frequent failure point, especially in fleet use.
AdBlue dosing module crystallisation
Urea deposits restrict dosing flow and trigger pressure faults.
AdBlue pump pressure low
Pump wear means it can no longer hit target pressure.
Tank quality / level sensor faults
False readings push the vehicle into countdown despite good fluid.
Our Trafic diagnostic process
- CLIP / Renault-level scan
- Live NOx and AdBlue dosing data
- Pump current-draw and pressure test
- Refractometer check on AdBlue fluid
Common Trafic repairs
- OE-coded NOx sensor replacement
- Crystallisation clean / injector replacement
- Pump assembly replacement
- Tank sensor replacement
- Reset SCR adaptations and clear countdown
