AdBlue Diagnostics – Hitchin

Langley Garage provides a well-reputed, professional AdBlue diagnostic and repair service at our workshop just outside of Hitchin.

Our technicians are experienced in dealing with all aspects of AdBlue repairs from diagnosing fault codes to resetting the system and are of course also happy just to top the fluid up if that’s all that’s required. We’re fortunate to have a very well-equipped workshop with state-of-the-art diagnostic technology and are confident that we provide the most reliable, competitively-priced AdBlue diagnostics in the Hitchin and Stevenage areas.

What is AdBlue?

AdBlue is a fluid that is added to diesel engines to help reduce emissions. This might need topping up in between services but don’t worry, because a light will come on in the dashboard to let you know when the AdBlue level is getting low.
