Hose/Line HVAC: Service and Repair
Important : In cars from M1992- which have R134a refrigerant, hoses with a thin polyamide film on the inside are used. This film protects the hoses
against the P.A.G. oil which is used in this system.
These hoses are extremely sensitive to bending. Bending damages the polyamide film, which in turn damages the hose, causing the risk of leakage.
1
Drain the refrigerant from the system, see "Refrigerant".
2
Change the faulty hose.
3
If necessary, fill with new compressor oil. Use new O-rings which are lubricated with synthetic Vaseline.
Torque tighten.
