01Common AdBlue warnings

Is your Citroen C4 showing one of these?

UREA Warning Light

This light often appears with an audible chime and indicates a fault within the AdBlue system. It may be due to a sensor, pump, or injector issue, even if the tank is full.

restart restriction

Your C4 will display a mileage countdown before the engine is prevented from restarting. This is a clear sign of a serious AdBlue system error that needs immediate attention.

AdBlue System Fault / Engine Fault

A generic engine or AdBlue system fault message can be triggered by the same underlying issues. The system will often put the car into a reduced power or 'limp mode'.

No Restart Countdown Active

Once the countdown timer reaches zero, your Citroën C4 will not start again after you switch it off. This is a standard feature designed to enforce emissions compliance.

Suspected NOx Sensor Failure

Faults with the NOx sensors are a very common reason for AdBlue warnings on BlueHDi engines. Diagnostic trouble codes may point to a sensor, but the issue can be complex.

02Our service

Our Citroen C4 AdBlue Delete & Removal service

Our mobile service begins with a full diagnostic scan to confirm the source of your Citroën C4's AdBlue fault. We then read the software from your engine's ECU and expertly modify it to disable the entire AdBlue system, a process also known as AdBlue Removal. This software-only solution stops the warning lights and countdown timers without touching any parts on the vehicle. Some newer, protected ECUs require specialist unlocking, which incurs an extra charge we confirm beforehand. We can also quote for optional extras such as performance remaps or DPF software solutions, all performed at your home or workplace.

  • No more AdBlue warning lights or countdown
  • No more AdBlue top-ups
  • We come to your home, work or chosen location
  • No Fix, No Fee: if we cannot complete the job, there is no charge
  • Lifetime Software Warranty on the software work

04Vehicle compatibility

Does your Citroen C4 have AdBlue?

Does your Citroën C4 have AdBlue? It's a feature on the BlueHDi diesel models, but not every C4 diesel is equipped with it. For your Citroën C4, we check the registration, engine, build specification and ECU details rather than assuming fitment or service support from its age or badge. Because compatibility depends on the specific engine, year, and emissions standard, the simplest way to be sure is to let us check your vehicle's registration.

Citroen C4 AdBlue help

Whether it's an AdBlue warning, a fault that keeps returning or a restart countdown, we can check your Citroen C4's compatibility and help you arrange the right service. Our mobile technicians come to your home or workplace.

Optional extras

Other services available for your Citroen C4

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 Citroen C4. We'll confirm which options are available for your vehicle.

Customer questions

Questions customers ask us

Still unsure? Send us your registration and a photo of the warning on WhatsApp.

Ask on WhatsApp
My C4's UREA light is on even after refilling. Why?

A persistent warning may indicate a system fault, but the fluid level and diagnostic results also need checking. It could be a failed sensor, pump, or injector, which our AdBlue delete software solution is designed to resolve.

Can you stop the restart countdown on my C4?

Yes. Our AdBlue software removal disables the system responsible for this countdown, preventing the non-start condition from occurring.

What if my Citroën C4's ECU is 'locked'?

Some newer C4 models have protected engine computers (ECUs) that need specialist unlocking before we can apply our software solution. We can identify this and will always confirm any extra cost with you before beginning work.

How do I know for sure if my C4 has AdBlue?

The engine badge or model year alone does not confirm AdBlue fitment or software support for your Citroën C4. Send your registration so we can check the engine, emissions specification and ECU details before confirming suitability and a quote.

What is an SCR or NOx fault warning?

SCR stands for Selective Catalytic Reduction, the technical name for the AdBlue system. A NOx sensor measures exhaust gases, and a fault with this sensor is a common trigger for AdBlue warnings on the C4.

I use my C4 for family travel. Is the fix reliable?

Absolutely. We are specialists who have been operating since 2012, and we provide a lifetime warranty on our software (subject to terms) for your complete peace of mind.

How long does the Citroën C4 AdBlue delete take?

The process is completed at your location and typically takes 1 to 2 hours, depending on your vehicle's specific ECU type and whether it requires unlocking.

Do you offer your mobile service in my area?

We are based near Slough and provide mobile service across London, the South East, and into wider England. Service is subject to technician availability.

How much does an AdBlue delete cost for my C4?

The price depends on the specific engine and ECU fitted to your car. Contact us with your registration and postcode for a precise, no-obligation quote.

Is AdBlue Delete the same service as AdBlue Removal?

Yes. They are just two different names for our software-only service. We do not physically remove the AdBlue tank or any other components from your vehicle.

Do you offer 24/7 emergency callouts?

Yes. Our standard hours are Monday to Sunday, 8 AM to 8 PM. Emergency callouts are available 24 hours a day, 7 days a week, subject to location and availability. An additional emergency callout charge applies and is confirmed before dispatch.
