Everything you need to now

What is AdBlue and why is it important?

AdBlue is a fluid used in diesel vehicles to reduce harmful emissions. It works with your car’s SCR (Selective Catalytic Reduction) system to convert NOx gases into harmless nitrogen and water.

What are the common signs of an AdBlue system fault?

Warning lights, dashboard messages like “AdBlue range,” “No start in X miles,” or poor engine performance are common signs that your AdBlue system needs attention.

Can I still drive my car with an AdBlue warning?

In most cases, yes—but only for a limited time. If not addressed, your vehicle may enter a no-start mode or reduced power mode. It’s best to fix it early to avoid being stranded.

What causes AdBlue system failures?

Crystallised injectors, faulty NOx sensors, low-quality AdBlue fluid, and software glitches are among the most common causes of failure.

How long does an AdBlue fix take?

Most AdBlue-related fixes take 1 hour, depending on the issue. We offer both in-house repairs at our Slough workshop and a mobile service in Ash, Surrey.

Is your AdBlue fix safe and permanent?

Yes. We diagnose and repair the root cause of the fault, not just clear warning codes—ensuring a reliable and long-term solution.
