Product Information
Full details
This guide is for vehicle owners and mechanics needing to replace or understand the CI Exhaust Temperature Sensor (Part Number: XEPS284) designed for placement before the Diesel Particulate Filter (DPF). Its key benefit is accurately monitoring exhaust gas temperature to ensure optimal DPF performance and emission control. A caveat is the necessity to verify fitment using the make/model tool or by contacting support, as direct compatibility requires precise vehicle matching.

FAQs
What does an exhaust temperature sensor before the DPF do?
It measures the exhaust gas temperature before it enters the Diesel Particulate Filter (DPF). This data is crucial for the vehicle's computer to manage the DPF's regeneration process (burning off soot) and maintain emission control.
How do I know if my exhaust temperature sensor needs replacing?
Symptoms can include a 'Check Engine' light, reduced engine power (limp mode), poor fuel economy, or issues with DPF regeneration. Specific diagnostic trouble codes (DTCs) related to exhaust temperature will usually point to a faulty sensor.
Can I install this sensor myself?
Installation requires mechanical aptitude and appropriate tools. It involves working with the vehicle's exhaust system and electrical connections. If you are not experienced, it is recommended to have a qualified mechanic perform the installation.
What does 'Placement on Vehicle: before soot particulate filter' mean?
This means the sensor is installed in the exhaust pipe upstream (before) the DPF unit, to measure the gas temperature entering it.
What is the thread size and spanner size for this sensor?
The thread size is M12 x 1.5, and it requires a 17mm spanner for installation or removal.
What is the cable length?
The cable length for this sensor is 420 mm.
What vehicles is this sensor compatible with?
It is compatible with specific models such as the AUDI A4 Allroad B9 (8WH, 8WJ) 2.0 TDI quattro (Euro 6) manufactured from 01/2016 onwards. Always use the make/model tool or contact support to verify fitment for your exact vehicle.
Are there any cross-reference part numbers?
Yes, this sensor cross-references with parts from ELTA AUTOMOTIVE (EX5405), INTERMOTOR (27438), LEMARK (LXT410), LUCAS (LGS7286), MEYLE (114 800 0188), and OEM VAG (8W0906088B, 8W0906088R).
Troubleshooting
Sensor not recognized by ECU / Check Engine Light (CEL) is on with related codes
Verify the sensor is correctly seated and the electrical connector is securely attached. Check the wiring harness for any damage or corrosion. Ensure the correct part number has been installed and that it is compatible with your vehicle model.
Inconsistent or erratic temperature readings
Inspect the sensor's exhaust connection for leaks. Ensure the sensor is not contaminated with excessive oil or soot. A faulty wiring connection or interference could also cause erratic readings.
DPF regeneration not occurring or occurring too frequently
This sensor directly influences regeneration cycles. If readings are inaccurate, the ECU may malfunction. Consult diagnostic tools for specific error codes related to exhaust temperature or DPF function. Ensure the sensor is properly installed and functioning.
Vehicle entering limp mode
A failing exhaust temperature sensor can trigger limp mode to protect the engine and emissions system. Re-verify sensor function and electrical connections. If issues persist, a professional diagnostic is recommended.
Pros and Cons
Pros
- Ensures proper DPF regeneration cycles.
- Helps maintain vehicle's emission standards.
- Designed for reliable performance in high-temperature environments.
- Facilitates accurate diagnosis of exhaust system issues.
Cons
- Requires careful fitment verification using specific vehicle tools.
- Installation may require specialized automotive tools and knowledge.
- Can be sensitive to extreme contamination in the exhaust stream.
- Relies on accurate data from other engine sensors to function optimally.
Setup, Compatibility & Care
Compatibility Verification: Before installation, it is essential to use the provided make/model tool or contact customer support to confirm that the XEPS284 sensor fits your specific vehicle. Cross-reference with OEM part numbers like VAG 8W0906088B or 8W0906088R is also recommended.
Installation: This sensor is designed to be installed in the exhaust system *before* the DPF. It features an M12 x 1.5 thread size and requires a 17mm spanner for installation. Ensure the vehicle is turned off and cooled down before attempting removal or installation. Disconnect the battery before working on electrical components. The sensor has a 2-pin D-shaped connector and a cable length of 420 mm.
Care: Regular checks of the exhaust system for any leaks or physical damage are advisable. While the sensor itself requires no routine maintenance, ensuring the exhaust system is in good condition will protect it from premature failure due to excessive vibration or external damage. Avoid using high-pressure water jets directly at the sensor or its electrical connector.
