Citroën AdBlue Removal & Delete Service
Fix Citroën AdBlue Faults, Warning Lights & Countdown Errors
Common Citroën AdBlue Problems
Citroën’s Euro 6 BlueHDi diesels (1.5, 1.6 and 2.0 litre) rely on an SCR module bolted just in front of the DPF. It’s clever—until the combined tank-pump unit fails, the heater goes open-circuit or the NOx sensor drifts. Then the cluster warns “Starting prevented in 1 100 km” and torque drops like a stone. If your C3, Dispatch or Berlingo spends life on private land, a farm, a building site or is sailing off-shore, Stoke Tuning’s Citroën AdBlue Removal kills the problem for good.
Real Faults We See on Citroën BlueHDi Engines
Typical faults we fix every week include P20E8 low-pressure codes on Dispatch vans after a cold snap, P20BA heater performance on SpaceTourer shuttles used for airport runs, plus the infamous P0420/P20EE efficiency codes on C4 Grand Picasso taxis. Owners can spend £800–£1 300 on a tank assembly (Citroën calls it a “urea reservoir”) only to be blitzed by a second NOx sensor at £300 a pop six months later. Fleet managers and export agents often decide a full delete is quicker, cheaper and permanent.
How Our Citroën AdBlue Removal Works
Your visit starts with a full DiagBox scan; we log freeze-frame data and DEF pressure to prove the failure point. Next, the EDC17C60 or MD1CS003 ECU is read on the bench using genuine Autotuner GPT probes—no cloned leads that risk a brick. Two encrypted backups go to our NAS and cloud server. In the calibration we:
Technical Process
• Change SCR strategy from closed-loop to inactive.
• Zero out DEF quantity, heater and pressure targets.
• Mask all 0x479x and 0x480x SCR DTC groups so no future limp mode.
• Leave DPF, boost and EGR diagnostics intact so the van still self-regenerates.
Hardware Steps & Road Test
While the file uploads we blank the injector with a stainless plug, cap the feed line and isolate the harness with heat-shrink. Many builders ask us to remove the tank to gain spare wheel access—happy to oblige, and we plug the vent to prevent fumes. Once flashed, a Midtronics stabiliser keeps voltage rock-steady while we clear historical codes and reset urea counters. A 14-mile validation loop from Longton to Stone logs EGTs, rail pressure and lambda trims; figures stay OEM-steady but the van now pulls clean past 3 000 rpm with no warnings.
