We offer 2 AdBlue Solutions - Repair or Delete!

AdBlue Delete

We come to you! We first read the the engine ECU data using our specialist tools. We then apply a AdBlue patch to the software that basically turns off the AdBlue from working. This also includes all the faults or dashboard warning messages.

AdBlue Repair

We first can carry out diagnostics and then quote to fix the AdBlue system. This would require you to visit JF Automotive workshops in Maidstone, Kent.

What Is an AdBlue Delete or Fix?

AdBlue systems can fail, causing warning lights, limp mode, or costly repairs. An AdBlue delete removes the system from your vehicle’s ECU, stopping those issues for good. An AdBlue fix adjusts the system to work properly without removal. Using pre-developed, tested files from JF Automotive in Kent, we tailor the solution to your diesel vehicle, whether you want it gone or fixed.

Frequently Asked Questions

Absolutely. We offer this service free of charge if the vehicle is brought back to us. We’ll be very surprised if that’s what you want after taking one of our remap products, however in the case of lease cars some customers prefer to put the car back to standard before returning the car. You might want it back to standard if you are visiting a dealer for warranty or service work, again we will do this for free. Should you lose your tuning files due to dealer actions or parts failure we will be happy to re-install the map onto your car free of charge where possible.

No, deleting the AdBlue system makes your vehicle illegal for use on public roads in the UK. Our AdBlue delete service, offered by Remaps UK, uses pre-developed, tested files from JF Automotive to remove the system from your ECU. This is intended only for vehicles used on private land, like racetracks or off-road sites. Driving a vehicle with an AdBlue delete on public roads breaks emissions laws and could lead to fines. We also offer an AdBlue fix to keep your system working legally—contact us to discuss your options.
If a main dealer updates your car’s software and wipes the remap, Remaps UK can sort it out. We’ll need to visit you again to reload the custom tune. This comes with a call-out fee and a charge for the time it takes, starting at £50. The exact cost depends on where you’re based in Kent or the South East, so just get in touch with us for a quote if it happens.

Terms and Conditions: AdBlue Delete Service

Any AdBlue delete service will make your vehicle illegal for use on UK public roads. These modifications, using pre-developed, tested files from JF Automotive, are suitable only for vehicles operated solely on private land, such as racetracks or track day events. By choosing this service, you agree to the following conditions:

  1. You must arrange appropriate transport (e.g., a car trailer) to collect your vehicle after the AdBlue delete, as it cannot be driven on public roads.
  2. We may remove the vehicle’s licence plates before you take it away, and you must submit a Statutory Off-Road Notification (SORN) to the DVLA.
  3. You are responsible for informing your insurance provider about all modifications. Not doing so could void your policy.
  4. Vehicles with an AdBlue delete are unlikely to pass the emissions test required for an MOT.
  5. Driving a Race Modified or uninsured vehicle on public roads is a criminal offence, which may result in significant fines.

By accepting this service, you agree to protect Remaps UK, JF Automotive Ltd, and its directors, officers, and staff from any costs, claims, losses, or liabilities (including reasonable professional fees) arising from your failure to follow these conditions. This protection lasts for six years from the date we release your modified vehicle to you.

How AdBlue Works in a Car

AdBlue is essential for modern diesel vehicles, reducing harmful emissions to meet strict environmental standards. This aqueous urea solution, made of 32.5% high-purity urea and 67.5% deionised water, is used in Selective Catalytic Reduction (SCR) systems to lower nitrogen oxide (NOx) emissions, which contribute to air pollution and smog. Understanding how AdBlue functions in a car involves its chemical process, vehicle system integration, and impact on performance and compliance, optimised for clarity and search engine visibility.

What is AdBlue?

AdBlue is a non-toxic, colourless, odourless liquid, standardised under ISO 22241 for consistent quality. It is not a fuel or additive but a separate fluid stored in a dedicated tank. Injected into the exhaust system, it treats emissions before they exit the tailpipe. AdBlue consumption is roughly 2-6% of diesel fuel usage, varying by vehicle, driving conditions, and engine size. For instance, a car using 10 litres of diesel per 100 miles may consume 0.2-0.6 litres of AdBlue over the same distance.

Role of Selective Catalytic Reduction (SCR)

The SCR system is central to AdBlue’s function. Diesel engines produce NOx during combustion, particularly at high temperatures. NOx harms health and the environment, causing respiratory issues and acid rain. SCR converts NOx into harmless nitrogen (N₂) and water vapour (H₂O) using AdBlue in a chemical reaction.

Exhaust gases pass through a diesel particulate filter (DPF) to remove soot, then enter the SCR catalytic converter. AdBlue is injected into the exhaust stream in precise amounts, controlled by the vehicle’s electronic control unit (ECU). The ECU monitors engine load, exhaust temperature, and NOx levels to optimise injection, ensuring efficiency and minimal waste.

Chemical Reaction Process

When AdBlue is injected into the hot exhaust stream (above 200°C), it undergoes thermal decomposition. Heat breaks down urea into ammonia (NH₃) and carbon dioxide (CO₂) via thermolysis:

[ (NH₂)₂CO + H₂O \rightarrow 2NH₃ + CO₂ ]

Ammonia enters the SCR catalyst, a ceramic or metallic substrate coated with materials like vanadium or zeolites. Here, it reacts with NOx in a reduction process:

[ 4NH₃ + 4NO + O₂ \rightarrow 4N₂ + 6H₂O ]

For nitrogen dioxide (NO₂):

[ 4NH₃ + 2NO₂ + O₂ \rightarrow 3N₂ + 6H₂O ]

These reactions reduce up to 90% of NOx, with optimal catalyst performance between 250°C and 450°C. Below this range, reactions slow; above, ammonia may oxidise, lowering efficiency.

Vehicle System Integration

AdBlue is stored in a 10-20 litre tank, typically near the fuel tank or under the boot, with a blue filler cap for identification. Sensors monitor fluid levels and quality, relaying data to the ECU, which triggers dashboard warnings for low levels or contamination.

The injection system includes a pump, injector, and dosing module. The pump pressurises AdBlue, the injector sprays it into the exhaust pipe before the SCR catalyst, and the dosing module ensures precise delivery. Over-injection wastes AdBlue and risks ammonia slip (unreacted ammonia in exhaust), while under-injection reduces NOx reduction.

Vehicles have safeguards for compliance. If AdBlue runs out or the SCR system fails, the ECU may limit engine power or prevent starting until resolved, ensuring drivers maintain the system.

Driver Considerations

AdBlue refills are needed every 5,000-10,000 miles, depending on driving habits. Available at fuel stations, auto shops, or service centres in 5- or 10-litre containers, it can also be refilled via nozzles at some stations. Contamination must be avoided, as impurities damage the SCR system. Spills require immediate cleaning to prevent corrosion.

In cold climates, AdBlue freezes below -11°C, but tank heaters thaw it during operation. Stored between -6°C and 25°C, away from sunlight, it lasts about one year.

Benefits and Challenges

AdBlue and SCR systems cut NOx emissions, aiding compliance with Euro 6 and similar standards, and improve fuel efficiency by optimising diesel engines. However, AdBlue costs (£0.50-£1.50 per litre) and SCR maintenance add expenses. System complexity increases failure risks, like injector clogging. Rural drivers may struggle to find AdBlue.

Conclusion

AdBlue is vital for cleaner diesel vehicles, reducing NOx emissions through SCR technology. Its precise chemical process and vehicle integration ensure eco-friendly performance. While adding costs, its environmental benefits make it essential for compliance and sustainability. Regular maintenance and refills keep vehicles efficient and road-legal, supporting cleaner air.
