Vehicle year alone does not guarantee compatibility. Volkswagen used several different climate-control systems within the same model and production year.

This bulb is intended for manual/analog HVAC controls with three rotary dials. It is not intended for Climatronic digital automatic climate-control panels with an electronic display.

Please compare the original bulb, connector base, and climate-control panel with the listing photographs before ordering. VIN verification is recommended when uncertain.
