Seeing an AdBlue or UREA light or a restart countdown on your Citroën DS3 dashboard can be incredibly frustrating. Our mobile technicians provide a specialist software solution to resolve these issues without needing to replace any parts. We come to you at your home or workplace. For a fast and accurate quote, please provide your vehicle registration and postcode.
24/7 Emergency Callouts Available
Emergency Mobile AdBlue Assistance. Additional emergency callout charge applies. Subject to availability.
01Common AdBlue warnings
The prominent AdBlue or UREA warning light on the dashboard indicates a fault has been detected within the SCR AdBlue system. This can be triggered by issues with the AdBlue tank, a sensor, the pump, or the injector.
Your DS3 is displaying a mileage countdown, after which the engine will be immobilised. This is a standard safety feature linked to the AdBlue system when a fault is logged or the tank is perceived as empty.
The system may fail to recognise a recent AdBlue refill or show an incorrect fluid level, often due to a faulty sensor within the tank assembly. This will trigger countdown warnings even when the tank is full.
Diagnostic checks may reveal fault codes relating to the upstream or downstream NOx sensors, which measure exhaust gas composition. A failure here will trigger the main AdBlue system warning as the car thinks it is polluting.
A common issue where the pump inside the AdBlue tank module fails, preventing the urea solution from being circulated. The failure of this critical component will immediately trigger dashboard warnings.
The system may log faults related to the AdBlue injector, which can become blocked with crystallised urea or fail electronically. This stops AdBlue being dosed into the exhaust, leading to a system error message.
02Our service
Our process begins with a full dealer level diagnostic scan to confirm the fault lies within the AdBlue SCR system. We then connect directly to your DS3's Engine Control Unit (ECU) and perform a specialist software modification, also known as an AdBlue Delete or AdBlue Removal. This service digitally deactivates the AdBlue system, stopping the dashboard warnings and the need for refills. Please note, some newer ECUs are protected and require an unlocking procedure at extra cost, which we confirm before starting any work. We can perform this service at your home or workplace, and can also quote for optional extras like performance or economy remaps at the same time.

04Vehicle compatibility
Does my Citroën DS3 have AdBlue? Not all diesel versions do, so it's a very common question. AdBlue, used by the SCR system on suitable diesel versions, was fitted to specific models to meet stricter emissions standards. For your Citroën DS3, we check the registration, engine, build specification and ECU details rather than assuming fitment or service support from its age or badge. Because exact specification depends on the engine, year and original emissions configuration, the only certain way to know is to provide us with your vehicle's registration so we can check for you.
Whether it's an AdBlue warning, a fault that keeps returning or a restart countdown, we can check your DS DS 3's compatibility and help you arrange the right service. Our mobile technicians come to your home or workplace.
Optional extras
While arranging your mobile AdBlue appointment, you can also ask about economy or performance remapping and our additional DPF and EGR software services for your DS DS 3. We'll confirm which options are available for your vehicle.
Customer questions
Still unsure? Send us your registration and a photo of the warning on WhatsApp.
Ask on WhatsAppYes, it is important to contact us before the countdown reaches zero. Our mobile AdBlue delete service can be performed while the countdown is active to prevent the vehicle from being immobilised.
This is a classic symptom of a hardware failure in the AdBlue system, not just an empty tank. It could be a sensor, pump, or injector fault, all of which are resolved by our software solution.
They are just two different names for the exact same service. It is a software only modification that deactivates the AdBlue system within the engine's management software.
Whether unlocking is needed depends on your Citroën DS3's specific ECU hardware and software. Some supported protected ECUs need specialist unlocking, which costs extra and is confirmed before booking; the vehicle's age alone does not establish this.
Yes, absolutely. The NOx sensors are a vital part of the SCR emissions system. A fault with these sensors will trigger AdBlue warnings, and our AdBlue delete software solution resolves these related issues.
For most Citroën DS3 models, the entire service typically takes between 1 and 2 hours from arrival. This includes our comprehensive pre and post diagnostic health checks.
