If you are experiencing issues with the AdBlue system on your Citroen Relay, you will likely have seen the following warning message on the dashboard: CANNOT RESTART IN 560 MILES REFILL ADBLUE. This essentially starts a mileage countdown/timer, and once you have exceeded the stated miles, your van will no longer start.
There could be a number of things causing the AdBlue error message to show up on the dashboard. Malfunctioned pumps, injectors, blockages, software issues, and faulty sensors are all examples of what might have caused your AdBlue system to fail.
Thankfully, we can provide you with a solution for your Citroen Relay, for models fitted with the Delphi DCM6.2A ECU, the Delphi DCM6.2C, and even the Delphi DCM7.1B used in the latest models.
The service we offer is an AdBlue removal. We will delete the AdBlue software from your van’s ECU, and all the AdBlue warning messages will cease to exist, leaving your van running perfectly without any mileage countdowns. Our solution is intended as an off-road/export service. You can also opt to give your Citroen Relay a stage-1 remap while we perform the AdBlue removal. This will make the van more enjoyable to drive with added torque and smoother power delivery.
