Yes there is a coolant sensor in the Renault megane.
You can find the map sensor behind the passenger side dashboard. You will need to remove the glove box in order to access the map sensor.
When you lift the bonnet look at the back to the right of the engine, there is a small vacuum tube leading to the map sensor that is clip locked to the bodywork approx 2" long by 1" wide.
Hi It is in the passenger side wing mirror. If you look on the underside there is a small bobble. That is it. You nedd to remove the glass to remove the sensor.

how do you remove a turbo from a 2005 Renault megane 1.9 dci
It uses a MAP sensor.It uses a MAP sensor.
The coolant temperature sensor in a Renault Megane Scenic is located on the right hand side of the engine as you are looking at it. It is located just above the TDC sensor.
On the passengers' side of the car you'll have to lift the plastic cover over the engine and look at the MAP sensor located at the passengers' end of the plastic cover (black in color and held in place by plastic clips--making up the entire MAP sensor assembly). There are three wires connected to the MAP sensor. Remove the wire assembly first. The MAP sensor is removed by twisting it counter clockwise (a small pair of channel locks might assist in removing it). There is a large spring just under the MAP sensor that pushes down on the PCV valve. Remove the MAP sensor and spring and then you can access the PCV valve. You might need a pair of plyers to remove the PCV valve. Installation of the MAP sensor assembly is done by replacing the spring, putting the MAP sensor assembly on the spring, assure the assembly is in the counterclockwise position and twisting it clockwise to reinstall.
at the back
There isn't one you take the 2 screws out to remove the map sensor in which plugs directly into a hole in the intake manifold that's where it gets its vacuum from.
Detach the 2 clips on each side of it and then remove it.
