Detailed Fitment and Function

SKP SKAX178 is an ambient air temperature sensor used on many Audi and Volkswagen vehicles to monitor outside temperature for the HVAC system and instrument display. This part number is commonly searched for Audi A6 ambient air temperature sensor replacement, Volkswagen Golf ambient temperature sensor, and Audi TT Quattro outside temperature sensor applications. It also cross-references Standard Ignition AX178 and OE number 8Z0820535 for the same application.

What This Sensor Helps Address

• Incorrect outside temperature readings on the dash or climate display
• HVAC temperature information that no longer matches ambient conditions
• Faulty ambient air sensor signals affecting climate system operation
• Replacement needs after sensor damage, corrosion, or wiring-related failure

Installation Notes and Tips

Verify the vehicle year, make, and model against the fitment list before ordering. The sensor position is listed as N/A in the catalog data, so confirm the original mounting location on the vehicle before installation. Inspect the connector and wiring for damage during replacement to help ensure proper sensor communication.

Quality Assurance

SKP replacement parts are cataloged for direct application matching across supported Audi and Volkswagen platforms. Confirm fitment by part number SKAX178, OE reference 8Z0820535, or the vehicle application before installation.
