If your Citroën Relay is displaying AdBlue warnings, SCR faults, or countdown-to-no-start messages, you already know how disruptive and expensive these issues can be. The BlueHDi system fitted in the Relay is prone to injector blockages, NOx sensor failures, and repeated dashboard errors, even after multiple replacements.

At Adblue Fix, we offer a permanent Citroën Relay AdBlue delete and NOx removal solution, designed to stop recurring AdBlue faults for good. With 15+ years of experience, a Slough workshop, and mobile service across the South East, we provide a fast, reliable solution for fleet operators and private van owners alike.

Why Citroën Relay Owners Choose AdBlue Delete

The Relay is one of the UK’s most popular large vans, but the AdBlue (SCR) system is notorious for repeated failures. Drivers often face limp mode, no-start countdowns, and high repair costs from dealerships, even after replacing AdBlue pumps, injectors, or sensors.

Common Citroën Relay AdBlue Issues Include:

• “UREA Fault – No engine start in X miles”

• Repeated NOx sensor failures

• AdBlue injector or pump malfunctions

• Persistent SCR warnings

• Limp mode during deliveries or work

• Expensive Citroën dealer repair quotes

Our AdBlue Delete Offers a Permanent Solution:

✅ No more AdBlue refills
✅ No more NOx fault codes
✅ No limp mode
✅ No countdown-to-no-start messages
✅ Permanent ECU programming (not a plug-in device)

Common Relay BlueHDi Fault Codes We Remove

• P20E8 – AdBlue Pressure Too Low

• P207F – Reductant Quality Fault

• P229F – NOx Sensor Performance Fault

• P20EE – SCR Catalyst Efficiency Below Threshold
