Extended Product Information
FAQs
What is the primary function of this exhaust temperature sensor?
This sensor measures the temperature of exhaust gases after the soot particulate filter. This data is crucial for the vehicle's Engine Control Unit (ECU) to manage the Diesel Particulate Filter (DPF) regeneration process effectively.
Which vehicle models is the CI Ignition XEPS285 compatible with?
It is specifically designed for AUDI A4 Allroad B9 2.0 TDI quattro Estate models manufactured from January 2016 onwards, meeting specific engine and emission standards (Euro 6).
What does the M12 x 1.5 thread size mean?
This refers to the physical threading on the sensor's body, indicating its diameter (12mm) and the pitch of the threads (1.5mm apart). This is a standard size for many automotive sensors.
Can I install this sensor myself?
Professional installation by a qualified mechanic is highly recommended due to the sensor's location in the exhaust system and its impact on engine management and emissions.
What are the OEM part numbers this sensor replaces?
This sensor replaces VAG part numbers 8W0906088F and 8W0906088S.
What is the cable length of this sensor?
The cable length for this sensor is 650 mm.
Does this sensor comply with emission standards?
Yes, it is suitable for vehicles meeting Euro 6 emission standards.
Troubleshooting
Check Engine Light (CEL) is illuminated
This can indicate a fault with the exhaust temperature sensor or related systems. Connect a diagnostic scanner to read fault codes. If the code points to the exhaust temperature sensor, inspect its wiring and connection. If the sensor itself is found to be faulty, replacement is necessary.
Reduced engine power or DPF warning light
An inaccurate temperature reading can disrupt the DPF regeneration process. Verify sensor readings with a diagnostic tool. If readings are abnormal, the sensor may need replacement. Also, check for exhaust leaks before or after the sensor.
Sensor connection loose or damaged
Inspect the 2-pin D-shaped connector for any signs of damage, corrosion, or looseness. Ensure it is securely seated. Clean contacts if necessary.

Setup, Compatibility & Care
Compatibility Check:
Before installation, it is crucial to verify fitment using the vehicle's make and model tool. This sensor is specifically designed for AUDI A4 Allroad B9 2.0 TDI quattro Estate models manufactured from January 2016 onwards, with AWD drive, 16 valves, 190 BHP (140 kW), and meeting Euro 6 emission standards. Cross-reference part numbers include VAG 8W0906088F and 8W0906088S.
Installation:
Installation should be performed by a qualified mechanic. The sensor is typically installed in the exhaust system after the soot particulate filter. It features an M12 x 1.5 thread for secure mounting and a 2-pin D-shaped connector that plugs into the vehicle's harness. Ensure the area is cool before attempting installation.
Care:
This sensor is designed for long-term operation and requires no routine user maintenance. However, it is essential to ensure the exhaust system remains free from excessive vibration and corrosion, which can impact sensor longevity. Regular visual inspection of the exhaust system during scheduled maintenance is recommended.
