Incorrect Outside Temperature Reading or A/C Not Working?

Replace One of the Most Common VW Climate System Failure Sensors.

The factory ambient air temperature sensor monitors outside air temperature and sends temperature data to the vehicle’s climate control and engine management systems.

Over time, exposure to:

• moisture
• road debris
• heat
• corrosion
• front bumper impacts

can cause the original sensor to:

• fail intermittently
• display incorrect temperatures
• lose signal
• trigger sensor fault codes

A failing outside temperature sensor may cause:

✔ Incorrect outside temperature display
✔ A/C system malfunction
✔ Climate control issues
✔ Temperature reading stuck at -40° or extremely high values
✔ Check engine light
✔ Poor HVAC performance

This OEM-style ambient air temperature sensor is designed to restore accurate temperature readings and proper climate control system operation.

Manufactured from durable automotive-grade materials, it provides reliable direct-fit installation for selected Volkswagen vehicles.
