How To Fix AdBlue System Malfunction
All modern cars with diesel engines have AdBlue systems to reduce harmful emissions from the exhaust system. However, these systems regularly malfunction.
There are a number of possible causes but the main culprit is crystallisation. To help you resolve this issue, we’ll give you an explanation of what crystallisation is and the fixes.

When everything else fails we come to rescue you with a permanent solution.
What Causes An AdBlue Malfunction?
The most common cause of all AdBlue faults is crystallisation. This occurs when the urea in Adblue fluid (diesel exhaust fluid) forms solid crystals that clog up the system.
As a result, the entire system stops working, and your car’s AdBlue warning light will keep turning on, even if the AdBlue tank is full.
It’s also possible that the fluid level in the tank is too low, causing your AdBlue light to come on. However, if you top up the tank and it doesn’t solve the problem, then it’s almost certainly being caused by crystallisation.
How Do You Fix It?
So, you’ve determined the issue isn’t a low AdBlue fluid level. Now, what do you do? Let’s take a look.
1. Car Dealer
If you’re getting an AdBlue error message, your first thought might be to take your car to the dealer.
Yet, this is the most expensive option, and it’s highly unlikely they’ll be able to fix the AdBlue system fault.
Dealers typically try to solve the problem by carrying out repairs that cost between £3,000 and £5,000. This is because they’ll most likely replace the AdBlue pump, tank, pipes, NOx sensor, and the other AdBlue system components.
However, most car owners start to experience AdBlue problems again within 12 months.
2. AdBlue Delete Technician
You could hire a technician to perform an AdBlue delete. The issue here is that most technicians are highly inexperienced and, quite frankly, don’t know what they’re doing.
Inexperienced technicians usually wipe your car’s original ECU settings and don’t keep a backup, meaning your vehicle can’t be returned to its original state if necessary.
So, you’ll have to pay the dealer around £1,000 to reset the ECU.
3. DIY AdBlue Delete Kits
There’s also the option of buying a DIY AdBlue kit and trying to fix the issue yourself, but these kits cost around £3,000.
Plus, without experience, you risk causing serious damage to your car’s ECU, which could result in a complete system failure.
