Adblue Removal Solution

AdBlue Removal & ECU Remapping – Stop AdBlue Faults for Good

Adblue Removal Solution

AdBlue is a diesel exhaust fluid (DEF) used in modern Selective Catalytic Reduction (SCR) systems to reduce NOx emissions. While essential for meeting emissions regulations, AdBlue systems are prone to failure, leading to dashboard warning lights, system malfunctions, and costly repairs.

At Onyx Performance, we offer a professional AdBlue delete service, electronically disabling the AdBlue system through a custom ECU remap. This removes AdBlue-related faults, warning messages, and unnecessary fluid consumption.

Why Remove the AdBlue System?

While AdBlue plays a role in reducing emissions, the system can cause significant operational issues and expensive repairs. Common problems include:

– AdBlue pump and injector failures, leading to costly replacements

– Blocked SCR catalysts, triggering engine warning lights

– AdBlue crystallisation, which damages sensors and pipes

– Reduced vehicle performance and power limitations

– “No Start” warning messages, preventing the vehicle from running

– Frequent AdBlue refills, adding extra running costs

For many commercial vehicle owners, fleet operators, and off-road users, removing the AdBlue system is a cost-effective way to prevent ongoing maintenance issues and unexpected breakdowns.

AdBlue Delete – How It Works

Our AdBlue delete service is performed through a professional ECU remap, permanently disabling the system. This includes:

– Electronic Deactivation – The ECU is recalibrated to disable AdBlue-related sensors, warning messages, and regeneration cycles.

– No More Dashboard Warnings – All AdBlue-related fault codes and engine management lights (EML) are removed.

– No More AdBlue Refills – The system is completely disabled, eliminating the need for AdBlue fluid.

– Vehicle Will No Longer Enter “No Start Mode” – Prevents the vehicle from becoming immobilised due to an AdBlue system failure.

Once completed, the vehicle will run as normal without any AdBlue-related faults, allowing for hassle-free operation.

Brought my Audi S3 in for a Stage 3 tune with a bigger turbo and full supporting mods. Things didn’t start smoothly — the Falcon turbo I had fitted from eBay turned out to be faulty and smoked heavily on the dyno.Instead of rushing the job or giving me attitude, they helped me swap it out for a proper Garrett PowerMax and carried on professionally. Then I ran into fueling problems caused by another low‑quality eBay part, and again they took their time, diagnosed the issue properly, fixed it, and made sure everything was right before continuing.After all the setbacks, they still mapped the car, spent a lot of time on it, and didn’t charge me anywhere near what the work was worth.They showed patience, honesty, and real skill. Very happy with the service and the way they looked after me.

This is the second time I have used Onyx Performance first time for wheel refurbishment and last time for remap and i would use their services again in the future without a doubt. They are very knowledgeable about what they specialise in, they are polite and you can see they care not only about what their customers want to do but also about what they can offer the customer. Thanks to the OP team.

Took my Mercedes C200 to Onyx performance for a stage 1 remap, my car is much quicker and throttle response is much better than before the remap. They also advise you about power and gains and the maps are tailored for your specific car and model, no stress on engine or gearbox. Thank Onyx , Brilliant work.
