Detailed Product Overview

The TS10520 is an air charge temperature sensor used by the engine control system to monitor incoming air temperature and support proper fuel and ignition calculations. Delphi builds this replacement part using OE-focused engineering knowledge developed over decades of supplying original equipment to global automakers. For drivers servicing Audi A4, Audi Q5, Volkswagen GTI, or Volkswagen Tiguan applications, this sensor helps restore the signal quality the engine computer expects.

This part cross-references Standard Ignition AX142 for the same application. Delphi TS10520 also cross-references OE-style part numbers 06B 905 379 D and 06B905379G for select applications.

Common Issues This Sensor Can Address

• Incorrect intake air temperature readings
• Check engine light related to sensor signal faults
• Rough idle caused by inaccurate air charge data
• Hard starting or drivability concerns tied to engine sensor input
• Reduced fuel control accuracy on supported Audi and Volkswagen models

Installation Notes and Tips

Verify connector shape, terminal count, and mounting style before installation. This Delphi TS10520 uses a male oval connector with pin terminals and bolt-on mounting, so matching the original sensor interface is important. Confirm vehicle fitment by year, make, model, and any chassis notes listed for 2002-2018 Audi and Volkswagen applications, including specific 2003 chassis breakpoints.

Quality Assurance

Delphi draws on 100 years of OE experience and supplier knowledge built into its aftermarket parts. That OE-focused background supports consistent fitment and sensor performance for replacement service on Audi and Volkswagen engine management systems.
