The Citroën Relay (2.0 and 2.2 BlueHDi) is a vital asset for London’s courier, construction, and transport sectors. However, it is also one of the most common vehicles to suffer from debilitating AdBlue system failures. If your van is displaying the “Check Anti-Pollution System” message or the “No Start in XXX Miles” countdown, your business is at risk of a total vehicle lockout. London AdBlue Delete provides a professional software-based solution to bypass these errors permanently.
Common Citroën Relay AdBlue Problems
The Relay’s BlueHDi system is complex, and when it fails, it usually results in “limp mode” or a starting prevention timer:
-
Sealed Pump Failure: On most Relay models, the AdBlue pump is built into the tank. When it fails, you are forced to replace the entire unit at a high cost.
-
Injector Blockages: AdBlue fluid can crystallise at the injection point, causing the system to detect a fault and trigger the engine light.
-
Nox Sensor Malfunction: The high-sensitivity Nox sensors on the Relay are prone to failure, especially under heavy-duty usage.
-
Communication Errors: Faults between the SCR module and the main ECU can cause false “AdBlue Low” warnings even when the tank is full.

The Benefits of a Professional AdBlue Removal
Choosing a digital Citroën Relay AdBlue Delete is the most effective way to protect your business from recurring repair bills. Instead of paying upwards of £1,400 for a new tank assembly that uses the same flawed technology, our software recalibration provides a lifetime solution.
By deactivating the SCR system within the ECU, we ensure that your van never enters “limp mode” due to urea-related faults. This allows your vehicle to remain on the road, performing reliably without the need for constant AdBlue top-ups or expensive sensor replacements.
Frequently Asked Questions
Can you reset the “No Start” timer if my Relay is already immobilised? Yes. Even if your van has reached zero miles and refuses to start, our mobile engineers can perform an emergency software reset and AdBlue Bypass on-site to get you back to work immediately.
Will my van still perform the same? Absolutely. A software AdBlue Removal does not negatively affect the power, torque, or fuel economy of your 2.2 BlueHDi engine. In fact, it increases reliability by removing the software triggers for power reduction.
How long does the service take? A professional software removal for a Citroën Relay typically takes between 60 and 90 minutes.
