Delphi TS30275 Exhaust Gas Temperature (EGT) Sensor - Before Turbocharger

Delphi EGT Sensor for Audi and Volkswagen

The Delphi TS30275 exhaust gas temperature (EGT) sensor is built for vehicles that monitor exhaust heat before the turbocharger. It uses OE-based engineering from Delphi’s long history supplying automakers, with the sensor positioned to deliver accurate temperature feedback for emissions and engine management systems.

Compatible with select Audi Q7, A6 Quattro, A7 Quattro, A8 Quattro, Q5, and Volkswagen Touareg applications, this Delphi TS30275 sensor is a direct-fit service part for the specified before-turbocharger location.

Key Features

• Exhaust Gas Temperature (EGT) sensor for emission control systems
• Before turbocharger mounting position
• Maximum temperature rating: 850.0
• 13.85 wiring harness length
• Oval connector with male connector gender
• 2 terminals with blade terminal type
• Threaded nut mounting type
• Includes sensor and instruction sheet

Detailed Description

Delphi TS30275 is an exhaust gas temperature sensor engineered for OE-style replacement in turbocharged diesel exhaust monitoring systems. The sensor is specified for the before turbocharger location and uses a 2-terminal blade connection with an oval male connector for proper interface with the vehicle harness. Delphi’s OE heritage is reflected in the design approach, drawing on decades of original-equipment experience for accurate signal delivery and dependable fitment.

This part cross-references 059 906 088 BJ and 059 906 088 CL for the same application. It is a strong match for Audi Q7, Audi Q5, and Volkswagen Touareg service needs where exhaust temperature monitoring is required ahead of the turbocharger. The Delphi TS30275 part number is also useful when verifying replacement against the original sensor reference.

What It Helps Address

• Fault codes related to exhaust gas temperature sensor performance
• Incorrect exhaust temperature readings before the turbocharger
• Emissions system monitoring issues
• Turbocharger protection strategies affected by sensor signal loss
• Driveability concerns tied to exhaust temperature feedback

Installation Notes and Tips

Install the sensor in the before-turbocharger position only on the listed applications. Confirm connector shape, terminal count, and harness length before installation, and compare the original part number and mounting style to the Delphi TS30275. Use the included instruction sheet during service and verify that the exhaust system is cool before removal or installation.

Quality Assurance

Delphi builds this sensor using OE-based knowledge developed through long-term original-equipment supply experience. That background supports consistent fit, electrical connection, and temperature sensing performance for the specified Audi and Volkswagen applications.
