Renault’s latest 1.5, 1.7 and 2.0 dCi Blue engines meet Euro 6 by squirting AdBlue into the exhaust. It’s clever until the combined tank-pump module seizes or a NO_x sensor drifts rich. The dash then warns “Anti-pollution fault – Engine start impossible in 700 km.” If your Trafic crew van lives on site, your Master motor-home is heading to Morocco, or your Kadjar works private farmland, Stoke Tuning’s Renault AdBlue Removal wipes the problem away in one visit and restores full torque.

We fix the same failures daily: Trafic and Master vans logging P20E8 low reductant pressure after a frosty night, Megane 1.5 dCi hatchbacks showing P20BD heater open-circuit, and Kadjar or Koleos SUVs kicked into limp mode by serial P20EE efficiency codes when the downstream NO_x sensor ages out. Dealer quotes of £1 100 for a “urea reservoir” plus £260 per sensor turn one fault into a money pit. Fleet managers, farmers and exporters prefer a permanent, reversible delete that stops the bills for good.

Your session begins with a full Clip & Bosch KTS scan. We log freeze-frame data, DPF soot mass and remaining starts, then remove the EDC17C84 or MD1CS006 ECU and place it on an ESD-safe bench. Genuine Autotuner GPT probes read the flash and EEPROM—no cloned cables that risk corruption. Two encrypted backups head straight to our NAS and a cloud vault before a single byte changes.

Inside the calibration we:
• flip the SCR mode flag from “active” to “inactive”;
• zero reductant flow, heater and pressure tables so self-tests pass silently;
• mask the full 0x4Dxx DTC block (P204F, P20E8, P208E, P20EE) while keeping DPF, boost and fuel diagnostics intact;
• lock out the BCM start-inhibit counter so countdowns never trigger.

While the file uploads, we blank the injector with a stainless plug, cap the feed line and depower the pump via OEM connector. Many Master camper owners ask us to drop the plastic urea tank to free water-tank space—we vent-cap the breather and underseal the chassis rails so nothing rattles. Flashing takes ten minutes on a Midtronics-stabilised supply. We clear historic codes, reset SCR counters and run a 20-mile validation loop from Longton to Stone and back over Hanchurch Bank. Live data proves lambda trims, boost and EGTs mirror factory spec while the van now pulls clean beyond 3 500 rpm with no warnings.
