Pressure Relief Valve V71: Where to Buy?

Where can I find the V71 pressure relief valve?

You can find them through search engines, including Google.

Okay, hier ist die Übersetzung:

"And please either consciously use two synonyms or, if they are not synonymous, deliberately separate them."

Does that part have the name "back pressure valve" or "check valve"?

Okay, please provide the German text you would like me to translate into English. I will only provide the translation.

Hello,

Manufacturer, model, year of manufacture?

Normally, the pressure relief valve is located somewhere downstream of the pollen filter in the direction of flow.
For example, in 'golf-like' vehicles from the Volkswagen Group, it's located on the passenger side, in the lower part of the dashboard, behind the glove compartment.
If you then remove the blower motor of the climate control system, you can see the recirculation flap and above it, the pressure relief flap.
Alternatively, you can remove the water reservoir cover, take out the pollen filter, and inspect the pressure relief valve.
Probably the actuator motor is going to cause problems, right?

Best regards,

Sure, here is the translation of the text from German to English:

'Renwal' is a word that means 'renewal.' It can be used as a noun or an adjective. As a noun, it refers to the process of making something new again. As an adjective, it describes something that is being renewed.

For example, you might say that a company is undergoing a 'renwal' process if it is changing its business model or introducing new products and services. You could also use the word 'renwal' to describe a person who is constantly learning and growing.
