Product Details

The EGT Sensor is used to monitor the exhaust gas temperature in the engine to help get an idea of the car’s air-fuel ratio from the exhaust gas. If your sensor has failed, you will not be aware if there are temperature issues in your engine that can cause catastrophic damage, and typically you will receive a check engine light on the dash if the sensor fails.

This set is sold as a kit, as Audi recommends replacing both sides at once.

*Note: Please check existing EGT sensor colors, these are for vehicles with 1 black sensor (left) & one brown/tan sensor (right)
