• Hella part number 014494251

Detailed Description

Hella 014494251 is an exhaust gas temperature sensor used in diesel emission control systems to measure exhaust temperature downstream of the diesel particulate filter. It fits 2009-2014 Audi Q7 and 2009-2010 Volkswagen Touareg, with the listed location after the diesel particulate filter. For Audi Q7 and Volkswagen Touareg diesel applications, this sensor supports accurate temperature feedback for the exhaust aftertreatment system.

This part cross-references Continental 49295 and Gates 12238 for the same application.

What It Is Used For

• Replacing a failed EGT sensor that triggers emission-related fault codes
• Restoring exhaust temperature monitoring after the diesel particulate filter
• Addressing inaccurate temperature readings in the aftertreatment system
• Correcting drivability issues tied to emission control faults
• Supporting proper diesel exhaust system diagnostics on Audi Q7 and Volkswagen Touareg models

Installation Notes and Tips

Verify the sensor location before installation: this application is listed as after the diesel particulate filter. Confirm the 2-pin connector style, bolted mounting point, and cable routing length match the original unit before replacement. Use the vehicle’s service information for torque and wiring routing details.
