BOSCH 0986259040 

Exhaust Gas Temperature Sensor (EGT Sensor) 

Technical Data

Product Information

Exhaust Gas Temperature (EGT) Sensor is a vital component for the efficiency and longevity of modern diesel engines. Specifically engineered to be installed before the soot particulate filter (DPF) , it monitors the extreme temperatures of exhaust gases entering the filter. This precise data allows the Engine Control Unit (ECU) to safely initiate and manage the DPF regeneration process, ensuring harmful soot is burned off effectively. This premium BOSCH sensor guarantees OE-level accuracy, featuring an M14x1.5 thread and a 760 mm cable for a perfect fit .

• ✔ High-quality BOSCH construction ensures exceptional thermal resistance and durability against exhaust vibrations .
• ✔ Prevents the DPF from clogging by supplying the ECU with accurate data needed for timely regeneration cycles .
• ✔ Direct, exact-fit replacement for multiple Mercedes-Benz OE part numbers .

⚠ Diagnostic & Installation Tip ⚠

Before replacing the exhaust gas temperature sensor:

• This specific sensor is located before the soot particulate filter (DPF) . Ensure you are replacing the correct upstream sensor, as downstream sensors have different calibrations and cable lengths.
• Ensure the exhaust system is completely cold to avoid severe burns and to reduce the risk of stripping the M14x1.5 threads in the exhaust pipe during removal .
• Route the 760 mm cable carefully , keeping it secured and away from direct contact with the hot exhaust pipes to prevent the wire insulation from melting.
