Product Details

HELLA 014494111 is an exhaust gas temperature sensor built for diesel emission control monitoring. It measures exhaust heat levels so the engine management system can track thermal conditions in the exhaust stream, including locations before the diesel particulate filter. This sensor is listed for 2014-2016 Audi A6 Quattro, 2014-2016 Audi A7 Quattro, 2014-2016 Audi A8 Quattro, and 2014-2016 Audi Q5, with one 2014 Audi A8 Quattro application also shown. This part cross-references Gates 12247 for the same application.

What It Helps Address

• Fault codes related to exhaust gas temperature sensor performance
• Incorrect exhaust temperature readings in diesel emission control systems
• DPF monitoring issues tied to sensor signal loss
• Driveability concerns caused by inaccurate exhaust thermal data
• Emission system warning lights on supported Audi diesel vehicles

Installation Notes and Tips

Verify the mounting style, 2-pole connector, and 242 mm cable length before installation. Confirm the sensor location on the vehicle, especially when replacing a unit positioned before the diesel particulate filter. Match the part number 014494111 to the original sensor specification and compare connector indexing and routing to the removed part.
