What Is AdBlue?

Understanding AdBlue & SCR

AdBlue is a chemical liquid used in Selective Catalytic Reduction (SCR) on diesel vehicles. Its purpose is to reduce harmful NOx emissions produced by the combustion process.

The fluid – composed of urea and demineralised water – is injected into the exhaust system just before an SCR catalyst. This triggers a chemical reaction inside the catalyst which converts NOx into harmless nitrogen and water vapour.

AdBlue was introduced by vehicle manufacturers in order to hit the stringent emission targets set out by governmental bodies. It is sometimes referred to as DEF (Diesel Exhaust Fluid).

The AdBlue and SCR system is a relatively complex creation, with an array of electronic sensors, modules and pumps. These systems can fail and can be expensive to maintain. A vehicle used regularly will consume large amounts of AdBlue, requiring frequent refills.

The Process

How AdBlue Delete Works

Our AdBlue delete service electronically disables the AdBlue system, removing all associated dashboard warnings and messages. Here's how we do it.

1
Vehicle Diagnostics
Full diagnostic scan of the vehicle's AdBlue and SCR system to assess the current state, identify any fault codes and determine the correct deletion method for your specific vehicle.
2
ECU Reprogramming
Disabling the AdBlue system is normally completed by reprogramming the engine management system. Some vehicles will require a small electronic unit to be hardwired into the vehicle.
3
Warning Removal
All AdBlue-related dashboard warning lights, messages and countdown timers are fully removed. The vehicle will no longer prompt for AdBlue refills or restrict starting.

Common Issues

Why Delete AdBlue?

The AdBlue and SCR system, while effective at reducing emissions, is one of the most problematic systems on modern diesel vehicles. Failures are common and repair costs can be substantial.

For off-road vehicles, agricultural machinery, plant equipment and competition vehicles where emissions regulations don't apply, removing the AdBlue system entirely is a practical and cost-effective solution.

  • AdBlue pump failure – expensive to replace
  • SCR catalyst contamination or failure
  • NOx sensor faults causing limp mode
  • AdBlue tank heater faults in cold weather
  • Vehicle refusing to start after AdBlue warnings
  • Frequent and costly AdBlue refills
  • Incorrect AdBlue contaminating the diesel tank

Customer Reviews

What Our Customers Say.

★★★★★

"The only place to go if you have a BMW N57 35d engine. Took my F34 335d GT there with an existing aggressive flash map to get a smoother custom tune, xHP gearbox map and EGR solution. Achieved 388hp / 789Nm and transformed the car with xHP stage 3. Worth the 6 hour round trip."

"Legend, had it tuned locally elsewhere and the tune came with a lot of issues. He took it to stock and retuned it all while I watched Netflix in the room next door."

FAQs

AdBlue Delete Questions

Is deleting AdBlue legal in the UK?+
Removing or disabling the AdBlue (SCR) system on a vehicle used on public roads is not legal in the UK, it's classed as tampering with an emissions system and will fail the MOT. We therefore only carry out AdBlue delete work for vehicles used strictly off-road, in motorsport, on agricultural or plant machinery, or being exported to markets where it's permitted.
Will an AdBlue delete pass an MOT?+
No. Since MOT emissions rules tightened, a vehicle with its AdBlue/SCR system removed or disabled will not pass an MOT for road use. This is why the service is sold for off-road, competition, agricultural and export use only.
Which vehicles can you carry out AdBlue delete on?+
We work on the full range of AdBlue-equipped diesels — BMW, Audi, VW, Mercedes-Benz, and commercial vehicles and plant machinery. Every solution is written custom to your exact ECU, never a generic file. Send us your vehicle details and we'll confirm. Peugeot or Vauxhall 1.5 BlueHDi? See our dedicated 1.5 AdBlue page.
Will removing AdBlue harm my engine?+
No, with a properly written calibration the engine runs cleanly without the SCR system, and it removes the risk of the AdBlue-related faults (crystallised injectors, failed pumps, NOx sensor faults) that can leave you stranded. The work is carried out by experienced technicians with your original file kept safe.
Is the AdBlue delete reversible?+
Yes. We read and back up your original ECU file before any work, so the vehicle can be returned to its standard AdBlue configuration at any time.
How much does an AdBlue delete cost and how long does it take?+
AdBlue delete starts from £325, with a discount available when it's done at the same time as tuning or another delete. Most are completed within a few hours, get in touch with your vehicle details for an exact quote and turnaround.
