Long time since these posts, but did replacing the module (4B0959501E) happen to clear the code? I have soft codes (no CEL) 18393 (P1985) Radiator fan control unit 2 J671 malfunction, and 18308 (P1900) Radiator fan actuator 2 open circuit / short to ground. Initial tech diagnosis at an import shop was the driver’s side fan itself, but that doesn’t seem right based on the discussion here. I’d greatly appreciate any sage advice on what to go after!
