Your temperature sensor is going to be located behind the engine on the driver side. You will need to remove the engine cover and you will need a torx bit (30) to remove the sensor. You can find the info for your car on this Mercedes-Benz maintenance booklet. I hope this helps.

As always, if you need help with this issue have one of our professional technicians come help you with a proper diagnostic of your Check Engine Light and help you replace this sensor as necessary.
