Hella 358181301 Exhaust Gas Temperature (EGT) Sensor

HELLA Exhaust Gas Temperature Sensor Overview

HELLA Exhaust Gas Temperature Sensor 358181301 provides direct exhaust temperature monitoring for turbocharged and emissions-controlled engines. It is built as a standard replacement sensor with OE-level fit and a plug-and-play style connection for service work on Audi A6 Quattro, Audi A7 Quattro, Audi A8 Quattro, Audi Q5, and Volkswagen Touareg applications.

Key Features

• Exhaust Gas Temperature (EGT) sensor for real-time exhaust heat monitoring
• Standard replacement grade for OE-style service fitment
• Brown female connector with oval shape, 2 terminals, and pin-style terminal design
• 340 mm cable length for the listed vehicle applications
• M14 x 1.5 thread size with thread sealer included
• Bolted mounting type for secure installation
• Direct replacement part number 358181301 for service and repair work

Detailed Description

HELLA 358181301 is an exhaust gas temperature sensor engineered to track exhaust heat in real time so the engine control system can respond accurately. On turbocharged and diesel emissions systems, that temperature data helps protect the turbocharger, diesel particulate filter, and related exhaust components from excessive heat. This sensor is a practical OE-style replacement for 2014-2016 Audi A6 Quattro, Audi A7 Quattro, Audi A8 Quattro, Audi Q5, and 2015-2016 Volkswagen Touareg models with the sensor location before the turbocharger. This part cross-references Delphi TS30273 and Dorman - HELP 91031 for the same application.

What It Helps Address

• Faulty exhaust temperature readings
• Check engine lights related to EGT sensor performance
• Turbocharger heat management concerns
• DPF and emissions system temperature monitoring issues
• Driveability problems caused by inaccurate exhaust temperature data

Installation Notes and Tips

Confirm the connector style, M14 x 1.5 thread size, and before-turbocharger location before installation. The bolted mounting design and 340 mm lead length should be matched to the original sensor routing on the vehicle. Because the product notes indicate assembly/disassembly by qualified personnel is required, installation should be performed by a trained technician familiar with exhaust sensor service and emissions-system procedures.

Quality Assurance

HELLA manufactures this EGT sensor as a standard replacement part with OE-level precision for emissions and thermal monitoring applications. The design focuses on accurate temperature tracking and durable service in demanding exhaust environments.
