If your Citroën Relay is showing AdBlue system faults, NOx sensor warnings, or dropping into limp mode, you already know how frustrating and expensive it can be. For tradespeople, delivery drivers, and fleet operators, these problems mean lost income and wasted time.
At Adblue Fix, we provide a permanent AdBlue delete and NOx sensor removal solution for the Citroën Relay. With 10+ years of experience, 500+ five-star reviews, and both a Slough workshop and mobile service across England, we are the trusted specialists for AdBlue problems in heavy-duty vans.
Why Relay Owners Choose AdBlue Delete
The Citroën Relay is built for tough work, but its AdBlue (SCR) system is a weak link. Instead of improving emissions, it often leaves owners with constant warnings, costly repairs, or a van stuck in limp mode.
Typical Citroën Relay AdBlue issues include:
-
Dashboard warning: “No engine start in 700 miles – AdBlue fault.”
-
Frequent NOx sensor failures.
-
Fault codes such as P20E8, P207F, P229F.
-
Main dealer repair bills running into the thousands.
-
Vans losing power and slowing down on jobs.
Our AdBlue delete service provides a permanent fix:
✅ No more AdBlue refills.
✅ No more limp mode.
✅ No more NOx sensor-related fault codes.
Citroën Relay AdBlue & NOx Fault Codes We Fix
Here are the most common Citroën Relay codes we remove permanently:
-
P20E8 – Reductant Pressure Too Low
-
P207F – Reductant Quality Performance
-
P229F – NOx Sensor 2 Bank 1 Performance
-
P20EE – SCR NOx Catalyst Efficiency Below Threshold
