As automotive experts, the team at Paisley Autocare understands the essential role every component plays in keeping your vehicle running smoothly. One such critical element in modern diesel vehicles is the AdBlue system. This innovative solution helps reduce the harmful emissions produced during combustion. However, like any vehicle system, it can experience faults. Here, we highlight the common AdBlue fault signs and offer practical solutions every car owner should be aware of.
Recognising AdBlue Fault Signs
One of the first indicators of an AdBlue system fault is the warning light on your vehicle's dashboard. Ignoring this might lead to increased emissions or a possible engine shutdown, making prompt attention crucial. Additionally, you may notice:
- Increased Exhaust Emissions: A sudden rise indicates the AdBlue system isn't functioning effectively.
- Engine Limp Mode: If your vehicle enters this mode, it limits engine power to prevent damage.
- Unusual Smells or Leaks: A pungent ammonia odour or visible AdBlue leaks can signal a problem.
Solutions and What to Do Next
Identifying the fault early can save you time and money on car repairs. Here's what you can do:
- Check AdBlue Levels: Ensure your AdBlue tank is filled. Sometimes the simplest solution is the most effective.
- Restarting with a Scan Tool: Occasionally, a fault can be cleared by restarting the system using a diagnostic scan tool, a task your car mechanic can perform.
- Seek Professional Help: Complex issues might require attention from a qualified technician. At Paisley Autocare, our team offers comprehensive ADAS Calibration as part of our advanced diagnostics services to ensure your vehicle's systems are properly aligned.
The Importance of Regular Maintenance
Regular vehicle repairs and maintenance can prevent many common issues, including AdBlue faults. For instance, ensuring your brake system is in top condition can impact your vehicle's overall performance and safety. Consider our Brake Check service alongside a routine inspection.

By understanding these fault signs, taking immediate action, and maintaining regular vehicle checks, you'll ensure your vehicle remains safe, efficient, and reliable.
FAQs
What is AdBlue and why is it important for my vehicle?
AdBlue is a diesel exhaust fluid made primarily of urea and deionised water. It plays a crucial role in reducing nitrogen oxide (NOx) emissions in vehicles with selective catalytic reduction (SCR) systems, making it essential for meeting environmental standards and ensuring your car runs efficiently.
What are the signs of low AdBlue levels?
A common sign of low AdBlue levels is a warning light on your dashboard. Additionally, you may notice a drop in engine performance or hear alerts prompting you to refill the AdBlue tank, especially when it becomes critically low.
How can I tell if my AdBlue system has a fault?
If you experience dashboard warnings or messages related to the AdBlue system, or if the vehicle enters limp mode, this may indicate a fault. Other signs can include unusual noises from the exhaust or changes in exhaust emissions.
What should I do if I suspect an AdBlue fault?
If you suspect there is a fault with your AdBlue system, it's advisable to consult a qualified mechanic as soon as possible. They can run diagnostics to identify the issue and recommend appropriate repairs to ensure your vehicle complies with emissions standards.
Can I drive my car with a malfunctioning AdBlue system?
While you may be able to drive for a short distance with an AdBlue fault, it's not advisable to ignore the problem. Driving for an extended period can lead to more significant issues, including potential engine damage or severe emissions violations.
How often should I check my AdBlue levels?
It's good practice to check your AdBlue levels regularly, especially before embarking on long journeys. Most vehicles will provide a warning when levels are low, but checking periodically can help you avoid running out unexpectedly.
Can I refill my AdBlue myself?
Yes, you can refill your AdBlue yourself as long as you use the correct type of fluid and follow your vehicle manufacturer's guidelines. Make sure to handle AdBlue with care, as it can be corrosive to paint and sensitive components if spilled.
What happens if I mistakenly use a different fluid instead of AdBlue?
Using the wrong fluid in place of AdBlue can cause significant damage to the vehicle's emissions system. If this occurs, you'll need to have the system drained and cleaned by a professional to prevent serious issues.
Is there a shelf life for AdBlue?
Yes, AdBlue has a shelf life of about 12 months once opened and can remain effective for about two years if stored properly in a sealed container. Always check expiry dates when purchasing and storing AdBlue.
