If nothing can be done, try to get yourself a thin, durable object, such as a paper clip, that will enable you to access the interior without losing a piece. We recommend that you also use a mixture of vinegar and hot water to optimize your results.

You should identify the two hoses specific to each nozzle. Try to tidy them and of course make sure they are properly connected. Use the same cleaning procedures described above. When they are cleaned, you should be capable to circulate water through them without any problems. Then plug them back in correctly, and repeat the test on your Audi A4. If it still doesn’t work, you now know that it doesn’t come from the sprinklers or the pipes.
After that, you should then check the pump. It is the one who sets out the product launch.
You will find it near the cleaning fluid reservoir under your Audi A4’s hood.

It is a very basic thing to do . First, remove the two screws that enable it to be fixed on your Audi A4.
Then, you must identify two power wires. They are mainly black and red. They have to be disconnected, but watch out, they must be reconnected in the right direction soon after, or you would create a short circuit on your Audi A4. A little tip to keep in mind: the red wire is a symbol of the + terminal. For example, put a piece of red tape on it to be certain you can find it. Do the same with the black tape on the bollard – . Thanks to this, you will be able to reconnect the wire of the right color without any problem later on.
Once completed, you can dispose of the old pump and insert the new pump on your Audi A4. Reconnect the cables in the right way using the tip, then just screw the two retaining screws back on.
Now run a test again.
Everything should be back to normal by now.
