Delphi TS30273 Exhaust Gas Temperature (EGT) Sensor - Before Turbocharger

Delphi EGT Sensor for Audi and Volkswagen

Delphi TS30273 is an exhaust gas temperature sensor built for precise temperature monitoring in the exhaust stream before the turbocharger. It is a direct-fit style replacement for select Audi and Volkswagen diesel applications, including Audi A6 Quattro, A7 Quattro, A8 Quattro, Q5, and Volkswagen Touareg models.

With OE-based engineering and a 13.26-inch wiring harness, this Delphi exhaust gas temperature sensor is made to match the original connection style and mounting layout for the listed vehicles. The TS30273 part number is a practical choice when replacing a failed EGT sensor on a 2014-2016 Audi A6 Quattro or a 2015-2016 Volkswagen Touareg before turbocharger service.

Key Features

Detailed Description

Delphi TS30273 is an emission control sensor that measures exhaust gas temperature ahead of the turbocharger, helping the engine control system monitor heat levels in critical diesel exhaust conditions. It is engineered for select 2014-2016 Audi A6 Quattro, A7 Quattro, A8 Quattro, and Q5 applications, plus 2015-2016 Volkswagen Touareg models. For 2014 vehicles, the sensor fits only vehicles manufactured on or after 03/17/2014. This part cross-references OE number 059 906 088 CE for the same application.

Common Issues This Sensor Can Address

• Fault codes related to exhaust gas temperature sensor performance
• Incorrect exhaust temperature readings before the turbocharger
• Diesel emissions system warning lights
• Turbocharger protection strategy triggered by sensor failure
• Driveability concerns tied to inaccurate exhaust heat monitoring

Installation Notes and Tips

• Verify the vehicle build date on 2014 applications before ordering.
• Confirm the sensor location is before the turbocharger.
• Match the oval connector, blade terminals, and 2-terminal layout to the original part.
• Inspect the harness routing and connector condition during replacement.
• Clear diagnostic trouble codes after installation and confirm proper sensor operation.

Quality Assurance

Delphi draws on OE supplier experience and original-equipment engineering knowledge to produce aftermarket replacement parts that follow the original application requirements. TS30273 is built to support the fitment and connection details specified for the listed Audi and Volkswagen models.
