I'm not too familiar with the scenic, but on most cars the sender unit can be accessed through a panel under the rear seats. If you lift the seats and then the carpet you might see a circular cover held down with screws around the circumference. I say might as I said I'm not familiar with the scenic

Usually you undo the cover and then you should see some wiring and 2 fuel lines going into the tank, one will be to the engine and the other the return from the engine. This whole unit will be the sender and intank fuel pump.

You will have to depressurise the fuel system before you attempt to remove the fuel lines. To do this look in your fuse box for a fuse marked INJ or fuel pump or similar. Remove the fuse and then start the car and let it run until it cuts out. You can now safely remove the fuel lines without getting covered in petrol! And then remove the sender and fuel pump unit and start diagnosing the problem.

Understeer is when you hit the wall with the front of the car.
Oversteer is when you hit the wall with the rear of the car.
Horsepower is how fast you hit the wall.
Torque is how far you take the wall with you.
