Citroën Relay AdBlue Delete: Fix for Large Van SCR & NOx Issues

The Citroën Relay is a workhorse for many tradespeople, delivery drivers, and fleet operators. However, its AdBlue (SCR) system can often be a source of frustration, leading to dashboard warnings, costly repairs, and reduced vehicle performance. These issues can result in lost income and wasted time for busy van owners. AdBlue Fix offers a specialised solution for Citroën Relay AdBlue system problems.
Common Citroën Relay AdBlue Issues
The Citroën Relay's AdBlue system, designed to reduce emissions, frequently causes problems for owners. Instead of performing as intended, it can lead to persistent warnings, expensive component failures, or the van entering a restricted power mode.
Typical Citroën Relay AdBlue system issues include:
Our AdBlue delete service aims to address these issues, allowing your van to run without the AdBlue system's common failures. This means no more AdBlue refills and no more AdBlue system related warnings.
- Dashboard warning: "No engine start in 700 miles – AdBlue fault."
- Frequent NOx sensor failures.
- Fault codes such as P20E8, P207F, P229F.
- High repair bills from main dealers.
- Vans losing power and slowing down.
Citroën Relay AdBlue & NOx Fault Codes We Address
The AdBlue system in the Citroën Relay can trigger a range of specific fault codes, indicating various malfunctions within the Selective Catalytic Reduction (SCR) and NOx sensor components. These codes often point to issues such as incorrect AdBlue fluid quality, pressure problems, or sensor failures, which can prevent the van from operating correctly or lead to limp mode.
Here are some of the most common Citroën Relay codes associated with AdBlue and NOx system issues:
- P20E8 – Reductant Pressure Too Low
- P207F – Reductant Quality Performance
- P229F – NOx Sensor 2 Bank 1 Performance
- P20EE – SCR NOx Catalyst Efficiency Below Threshold
- U029D – Lost Communication with NOx Sensor
