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. 🥳
Hello, I have an Audi a3 20 to 140 phase 2, I'm looking for the pressure switch everywhere, I can't find it, I looked carefully at the air conditioning compressor, I can't find it, I heard that on certain models it is located near the front left light, so where is it?
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.

Hello everyone
Air conditioning problem on Sharan 2.0 tdi from 2008.
The compressor starts and stops, the fan does not turn.
air conditioning charged properly (at the dealership) no leaks.
I was asked to check the pressure switch...
Do you have any idea please….Thank you

Good morning,
I can't unplug the pressure switch.
The plug is even a little broken, but the connection is still maintained somehow, is there a way to test the pressure switch at the outlet?
Voltage, current, resistance?

Hello, I have a Navara 2.5 dci 190hp 2007 and I can't find it.

Hello, sorry for the delay in replying. First of all, you need to know why you want to replace the pressure switch? Either there is a leak at the pressure switch (so no more gas) or you have a connection problem (so you need to empty the air conditioning).

Hello, I own a 2012 Volvo C70, can I change the seat without emptying the air conditioning?
