Detailed Description

Built for diesel exhaust temperature measurement, this HELLA sensor helps the engine control system track heat levels in real time so critical components can be managed before excessive temperatures cause damage. Part number 014494691 is specified for the exhaust stream before the diesel particulate filter on 2009-2012 Audi Q7 and 2009-2010 Volkswagen Touareg models. This part cross-references Continental 49294 and Delphi TS30184 for the same application.

What It Helps Address

• High exhaust temperatures that can stress the turbocharger
• Incorrect EGT readings that can affect emissions control strategy
• Diesel particulate filter heat management concerns
• Check engine lights related to exhaust temperature sensor faults
• Driveability issues caused by inaccurate exhaust temperature data

Installation Notes and Tips

Verify the sensor location before the diesel particulate filter and confirm the 2-pole connector matches the original unit. The bolted mounting design and 460 mm lead length should be checked against the existing harness routing before installation. Use the vehicle’s service information to confirm application details for your Audi Q7 or Volkswagen Touareg before replacement.
