Leaks, Finding With UV Leak Detection System: Notes
WARNING: This page is about a different car, the 2023 Volkswagen Arteon. However, it is still accessible from the selected car via links, so may be relevant.
Special tools and workshop equipment required
- Leak Detection System: VAS 6201 or commercially available
- Leak Detection Additive (depending on the required refrigerant oil). Refer to the Parts Information.
- A/C Service Station with a possibility to add UV leak detection additive
- Add UV leak detection additive to the refrigerant circuit using the A/C Service Station. Refer to Add UV leak detection additive to the refrigerant circuit using the. .
- Leaks, Finding with UV-Lamp. Refer to Check for leaks on the refrigerant circuit using. .
- Refrigerant and often refrigerant oil escape when there is a leak in the refrigerant circuit. So that the oil will become visible under UV light, Leak Detection Additive must be filled into the refrigerant circuit.
- Leaks which only occur when the A/C compressor is running can be detected using UV leak detection.
- A/C system must be operated for a minimum of 60 minutes so that the additive distributes itself in the entire refrigerant circuit.
- The Leak Detection Additive can be added directly to the open circuit, or after draining the circuit, using the A/C Service Station Owner's Manual.
