AdBlue System Faults

An AdBlue system fault can be some of the trickiest to diagnose.   AdBlue is actually a brand name, a worldwide trademark of VDA. This chemical needs to be 32.5% solution of urea in deionised water. Without this solution the correct operation for an advanced pollution control technology installed in the exhaust system simply wouldn’t work. This exhaust technology is Selective Catalytic Reduction (SCR).

AdBlue is a clear liquid and handling it is safe. The Urea solution encapsulates the toxic ammonia (needed for the depollution technology to function). AdBlue does not mix with Diesel and has a separate tank (reservoir) for refilling.

The SCR process converts harmful nitrogen oxides produced by the vehicle’s engine into nitrogen and water using AdBlue.

At Cardiff Auto Electrics, we have built up a wide range of experience diagnosing and repairing AdBlue faults on vans and cars.  If you have an AdBlue system fault, we recommend that you book in for us to check the systems and advise the best course of action to resolve the issue.
