How to Clean the AdBlue Injector on an Audi

Model: Audi Audi Various
Part: Checks and maintenance

Video tutorial

In this video, see how our YouTuber rightly gets frustrated with manufacturers claiming that the AdBlue injector requires no maintenance, while clearly demonstrating that this is not true. The AdBlue injector on this Audi (the brand of the vehicle is not crucial) is completely clogged, covered in crystallised additive deposits that prevent the component from functioning.

He shows that it can be easily cleaned with a hook or a small screwdriver. We add an even simpler suggestion: AdBlue is water-soluble, so a few minutes in hot water will dissolve the deposits like snow in the sun, with no effort and without the risk of damaging the component.
