Warranty extension 26-01-049G TSB
A bulletin is a manufacturer's communication to its dealers, as NHTSA indexes it. The summary is NHTSA's. The document is the manufacturer's: read it at NHTSA. A bulletin is not a recall, and listing a model year does not mean every vehicle of it is concerned.

NHTSA's summary
Certain G80 (RG3) and G90 (RS4) vehicles equipped with the 2.5T‑GDI Theta III or 3.5T‑GDI Lambda III engine may experience reduced air‑conditioning performance due to a refrigerant leak originating at the Thermostatic Expansion Valve (TXV).This condition may be caused by improper installation of the liquid and suction pipe O‑rings at the TXV connection point. This bulletin provides instructions to replace the TXV O‑rings at the liquid and suction pipe connections to correct the condition.
