How To Reset AdBlue Warning Light
All modern diesel vehicles have an AdBlue (Diesel Exhaust Fluid) system. It’s designed to transform harmful emissions from your diesel fuel into a mixture of water vapour, nitrogen, and CO2. Yet, this system can cause a wide range of issues.
One of the most common problems is an AdBlue warning light that won’t stop flashing, no matter what you do. In this guide, we’ll discuss all of the possible solutions.

Top Up The AdBlue Tank
Naturally, if the warning light is telling you that your car’s AdBlue level is low, the first thing to do is top up the tank with AdBlue fluid.
If the light still doesn’t turn off, start the engine and let it run for a few minutes so the system can detect the new AdBlue level. You can also try driving your vehicle a few miles to see if this fixes the problem.
What If The Warning Light Is Still On?
If the light doesn’t go out, it means there’s an issue with your AdBlue system. The most likely cause is crystallisation, which occurs when the urea in AdBlue forms solid deposits.
This clogs up the Selective Catalytic Reduction (SCR) system, causing damage to your car’s exhaust system and other components.
Let’s take a look at how you can fix this.
1. Car Dealership
You could take your vehicle to the main dealer. However, this comes with its own set of problems. Firstly, they’ll charge you between £3,000 and £5,000 to repair the system.
Plus, once they’ve repaired the vehicle, the issue is likely to occur again within 12 months. Imagine paying £5,000 for repairs only to find that your AdBlue light comes back on again within a year or so.
Simply put, avoid this option.
2. AdBlue Cleaner
AdBlue cleaner costs around £50 and is a good option for maintaining your AdBlue system. However, it won’t have any effect if you use it once the system has already crystallised.
So, using AdBlue cleaner won’t solve any issues with your car’s AdBlue sensor.
3. Inexperienced Technicians
Many inexperienced technicians out there offer to perform an AdBlue reset on a “no fix, no fee” basis. This might seem tempting, but these technicians lack the required expertise. Hence that offer, they are not confident that they can fix it.
As a result, they often wipe the original settings from your car’s ECU. Then, you’ll need to pay around £1,000 to your dealer to reset the ECU for you.
4. DIY
You could buy an AdBlue delete kit and try to solve the problem yourself. However, the kit costs around £3,000, and without experience, you could easily break the vehicle’s ECU.
5. AdBlue Delete Service
The most reliable and affordable option is to use our AdBlue delete service the only one of its kind in the UK. This service disables the AdBlue system, so you’ll never have an issue with the AdBlue warning light again.
