Introduction: Why Replacement Matters
If your 1.5 dCi diesel engine shows Check Engine Light with codes P0544 or P0545, your Exhaust Gas Temperature (EGT) Sensor may be faulty. Symptoms include:
-
Reduced engine performance
-
Limp mode activation
-
Interrupted DPF regeneration
-
Higher fuel consumption
Replacing the EGT sensor (OEM 8200921749) restores accurate exhaust temperature readings and prevents long-term engine or DPF damage.
Tools and Safety Precautions
Before starting, make sure you have:
-
Socket wrench set
-
Torque wrench
-
Screwdrivers
-
Penetrating oil (for rusted connections)
-
Safety gloves and goggles
Safety tip: Work on a cold engine to avoid burns from the exhaust system.
