How to clean the AdBlue injectors on the Audi A4 B9 version

Model: Audi A4 B9 - Years 2014-2024
Part: Fuel injectors

In this video we see how to clean the AdBlue injectors on an Audi A4 B9 version; of course, first of all we will find where they are located: we will have to raise the front hood, and remove two bolts from under the cover of the engine block, which will allow us to remove a plastic partition that protects a series of components. Among these are also our injectors: it will be enough to unscrew the small bolt that holds them screwed upside down, and lift them. In fact, we see that they are very encrusted with additive. The best and simplest thing we can do to clean them is to immerse them in hot water, and then with a slightly damp cloth, also clean the part that screws in, in order to bring them back to the best conditions, we screw the bolt back in, put the partition back in place and it's done.
