Hello, I have an Audi a3 20 tdi from 2004 and I'm looking everywhere for the pressure switch but I can't find it. I looked carefully at the air conditioning compressor, I can't find it and I saw that this is normally where it is located, so if someone can enlighten me a little on it, that would be great. 🥳
Thanks! Very useful on my 2007 Leon 2 1.6, it's exactly the same part
Hello, it's much more complicated than in your tutorial... I had to remove the front bumper and the windshield washer reservoir on my A3 8P...
Hello. I have taken note of this tutorial. I have the same vehicle Audi A3 140hp from 2005. I would have 2 questions however.
1 - Is there a seal that needs to be loaded when replacing the pressure switch?
2- Is an air conditioning recharge necessary afterwards? (I was told about a valve that would make it unnecessary)
Thank you for your answers.
Victor
