To change the spark plugs on a Renault Scenic Expression, first, ensure the engine is cool and then disconnect the negative battery terminal. Remove the engine cover if applicable, and carefully detach the ignition coil or spark plug wires to access the plugs. Use a spark plug socket and ratchet to unscrew the old plugs, then install the new ones by hand to avoid cross-threading, and tighten them to the manufacturer’s specifications. Finally, reconnect the ignition coils or wires and the battery terminal before starting the engine.
Take the old one out and put a new one in

My Scenic is a 2001 model with a 1998cc motor. The engine type is F4R which has 4 spark plugs. The spark plugs use a 5/8" socket plug. You will need about a 15cm extension on the socket as the plugs are situated deep inside the engine.

You are not being very specific here, but it being deisel, the first thing I would check is the glow plugs, try replacing them, fairly easy job not expensive.
The spark plug gap for a Renault Scenic 16v 1.6 2007 model is typically set to 0.9mm or 0.035 inches. It is important to ensure the correct gap is maintained to allow for proper ignition and combustion within the engine cylinders. Using a gapping tool, carefully adjust the electrode distance to the specified gap measurement before installing the spark plugs.
To remove the boot panel on a Renault Scenic, start by opening the boot and locating any screws or fasteners securing the panel. Use a suitable screwdriver or tool to remove these fasteners.
