London AdBlue Delete provides a specialist digital solution for the heavy-duty SCR emission system failures that frequently cripple the Citroën Relay. Owners of the Citroën Relay (2.0 and 2.2 BlueHDi), a mainstay for courier fleets and construction trades, often face the “UREA” warning or the “Emissions System Fault” message. These issues are typically caused by failed tank sensors or pressure loss in the urea delivery pump. Rather than facing a high-cost mechanical Urea Repair at a Citroën commercial centre—where replacing a full tank assembly can cost thousands—our mobile engineers provide a permanent AdBlue Delete. By professionally reprogramming your Relay’s ECU, we ensure the vehicle no longer requires additive fluid, removing the risk of “limp mode” across Croydon, Barnet, Ealing, and Bromley.

The “Starting Impossible in XXX Miles” countdown is a major threat to any business using a Citroën Relay, as it leads to a total vehicle lockout. At London AdBlue Delete, we offer an emergency AdBlue Countdown Fix that resets these restrictive software timers on-site. We serve Wandsworth, Lambeth, and Hillingdon, bringing professional-grade programming tools directly to your depot or job site. For many Relay owners, we also perform a Nox Sensor Delete as part of our AdBlue Removal package, as these sensors are highly prone to failure on the BlueHDi engines, triggering persistent engine management lights in Newham, Havering, and Brent.

Our mobile Citroën Relay AdBlue Removal is 100% software-driven and performed via the OBD port, ensuring no physical components are removed or modified. We cover every London borough, including Enfield, Lewisham, and Haringey, providing a clean and efficient software bypass that protects your van’s performance and reliability. Whether you drive a Relay Enterprise, Worker, or a Luton conversion, our AdBlue Delete is the most effective way to avoid the high costs of dealership maintenance. For Citroën operators in Southwark, Islington, Westminster, and Tower Hamlets, we provide a lifetime-guaranteed software fix in Greenwich, Hammersmith & Fulham, and Camden.
