How the Vauxhall AdBlue system works
Covers: Vivaro, Movano, Combo, Insignia and Astra diesel.
Depending on year, Vauxhall vans use either Renault-derived or PSA-derived SCR hardware. Later Vivaro and Combo vans share the PSA BlueHDi tank module.
Common Vauxhall AdBlue faults we see first
- Tank module faults on PSA-based Vivaro and Combo
- Pump and heater faults on Renault-based Movano
- Countdown warnings that persist after refill
- NOx sensor plausibility codes
What we check before quoting
We identify which platform your Vauxhall uses before diagnosis, as the fault strategy differs between them.
Send us the registration and the exact dashboard message or fault code by WhatsApp. We confirm the ECU type and whether the job is suitable before arranging a visit.
Who this is for
Vivaros and Movanos converted for motorsport support or prepared for export are the main off-road cases.
Important — legal position
Disabling or removing a working emissions control system on a vehicle used on UK public roads is not lawful and will fail an MOT. This service is only for vehicles used off-road, in competition, on private land or exported. Road-registered vehicles in UK use get diagnosis and repair instead.
