Delphi TS30258 Exhaust Gas Temperature Sensor
The Delphi TS30258 is an exhaust gas temperature (EGT) sensor built for diesel emission control systems that monitor heat levels after the particulate filter. It is a direct-fit style replacement for select Audi applications and uses OE-based engineering from Delphi’s long history supplying automakers.
- Exhaust Gas Temperature (EGT) sensor for emission control monitoring
- Fits after particulate filter applications
- Maximum temperature rating: 850.0
- 8.27 wiring harness length
- Oval female connector with 2 terminals
- Blade terminals with male terminal gender
- Threaded nut mounting type
- Includes sensor and instruction sheet
OE-Style Fit and Function
Delphi TS30258 is engineered for vehicles that rely on accurate exhaust temperature feedback to manage aftertreatment performance. It fits 2014-2016 Audi A6 Quattro, after particulate filter; 2014-2016 Audi A7 Quattro, after particulate filter; 2014-2016 Audi A8 Quattro, after particulate filter; and 2014-2016 Audi Q5, after particulate filter. This part cross-references Audi 8K0 906 088 B for the same application.
Common Issues This Sensor Addresses
- Fault codes related to exhaust gas temperature readings
- Incorrect aftertreatment temperature monitoring
- Diesel particulate filter regeneration concerns tied to sensor input
- Intermittent sensor signal loss from connector or terminal wear
- Emission system warning lights caused by a failing EGT sensor
Installation Notes
Confirm the sensor position before installation; this unit is specified for the after particulate filter location. Match the oval connector, 2-terminal layout, and threaded nut mounting style to the original part, and verify harness length and routing before final tightening. Always compare the replacement part number and vehicle application to the original sensor on the Audi A6 Quattro, A7 Quattro, A8 Quattro, or Q5.
Quality Assurance
Delphi builds aftermarket parts using OE heritage and technical knowledge developed through more than 100 years of supplying original equipment to major automakers. That background supports consistent fitment and sensor performance for emission control service.
