Delphi TS30181 Exhaust Gas Temperature (EGT) Sensor - After Particulate Filter

Delphi TS30181 Exhaust Gas Temperature Sensor

The Delphi TS30181 is an exhaust gas temperature (EGT) sensor built for emission control monitoring after the particulate filter. It uses Delphi OE heritage and application knowledge to deliver the signal accuracy needed for modern diesel aftertreatment systems. This Delphi TS30181 EGT sensor is a direct-fit option for select Audi Q7 and Volkswagen Touareg applications.

Key Features

• Exhaust Gas Temperature (EGT) sensor for emission control systems
• Positioned after the particulate filter
• Maximum temperature rating: 850.0
• 48.03 wiring harness length
• Oval female connector with 2 terminals
• Blade terminals with male terminal gender
• Threaded nut mounting type
• Includes sensor and instruction sheet

Detailed Description

Delphi TS30181 monitors exhaust temperature downstream of the particulate filter, helping the engine control system track aftertreatment conditions and manage regeneration strategy. Built from Delphi’s OE experience, this sensor is engineered for the demands of diesel emission control and the thermal environment found in Audi Q7 and Volkswagen Touareg applications. If you are replacing a faulty EGT sensor on a 2009-2014 Audi Q7 or a 2009-2010 Volkswagen Touareg, TS30181 provides the correct fitment and connector style for the listed position.

This part cross-references 059 906 088 AC and 231018 for the same application.

What It Helps Address

• Fault codes related to exhaust gas temperature sensor performance
• Incorrect aftertreatment temperature readings
• Diesel particulate filter regeneration monitoring issues
• Emission control warning lights tied to downstream exhaust sensing
• Driveability concerns caused by inaccurate exhaust temperature data

Installation Notes and Tips

Install the sensor at the after particulate filter location specified for the vehicle. Confirm the oval connector, 2-terminal layout, and threaded nut mounting match the original part before installation. For Audi Q7 and Volkswagen Touareg fitments, verify harness routing and connector orientation to avoid strain on the lead and to ensure a secure electrical connection.

Quality Assurance

Delphi draws on more than 100 years of OE experience and supplier knowledge from top automakers, with aftermarket parts built from that heritage. The TS30181 is manufactured to support the fit, function, and thermal requirements expected in emission control service.
