Connect Digital Potentiometer (VAG 1630) between sensor harness connectors. Turn ignition on. Adjust potentiometer to appropriate setting and ensure outside temperature display corresponds to setting. See OUTSIDE TEMPERATURE DISPLAY TESTING table.
- If temperature display corresponds to potentiometer setting, replace outside temperature sensor. If temperature display does not correspond to potentiometer setting, check wiring. Refer to WIRING DIAGRAMS . If wiring is okay, replace temperature display.
