How to Clean a Clogged AdBlue Injector

Model: (Various brands) Various
Part: AdBlue warning light

Video tutorial

The video refers to a French car from the PSA group. The mechanic accessed the injector, which was completely clogged.

He removed it and soaked it for a few minutes in a specific cleaner, such as Liqui Moly 4066, which you can find on Amazon for £11.09 with free delivery. The injector was indeed very encrusted, but urea is water-soluble, so it takes very little to remove seemingly terrible deposits.

The same should be done on the other half of the injector, which remains on the pipe, and we will need to operate with a sprayer to remove the thicker deposits with a hook. Then we can reassemble the other part, and the job is complete.
