Evidence Of Leaks

WARNING: This page does not describe the selected car, but rather 6 other vehicles, including the 2024 Audi SQ5, 2024 Audi Q5 e, 2024 Audi Q5, 2023 Audi SQ5, and 2023 Audi Q5 e. However, it is still accessible from the selected car via links, so may be relevant.

External damage, for example, can cause a leak in the refrigerant circuit. The small quantity of refrigerant escaping from minor leaks can be detected, for example, by using an electronic leak detector or by introducing a UV-leak detection additive into the refrigerant circuit. Electronic leak detectors can recognize leaks with refrigerant losses of less than 5 grams per year.

NOTE:

Use leak detectors designed for the type of refrigerant. For example, a leak detector for refrigerant R12 will not work with R134a because R134a refrigerant has no chlorine atoms so the leak detector will not respond to it.
