Solution

1. Preparation

Tools Required: OBD-II scanner, socket set, fuel line disconnect tool, multimeter, flashlight, safety glasses, gloves.
Ensure the vehicle is parked on a flat surface and the engine is off.
Disconnect the battery to prevent any electrical short circuits.

2. Inspect Fuel Lines

Locate the fuel lines running from the fuel tank to the engine.
Use a flashlight to examine the lines for cracks, abrasions, or any signs of wear.
If a leak is found, proceed to replace the damaged section of the fuel line using a fuel line disconnect tool.

3. Check Fuel Injectors

Remove the engine cover if necessary to access the fuel injectors.
Inspect each injector for any signs of fuel leakage around the seals.
Replace any faulty injectors with new ones, ensuring to use the correct specifications for the Renault Clio V.

4. Examine Fuel Tank and Pump

Safely raise the vehicle using jack stands if necessary to access the fuel tank.
Inspect the fuel tank for any signs of rust, corrosion, or cracks.
If the fuel pump is suspected to be leaking, remove it from the fuel tank and replace it with a new unit.

5. Inspect Fuel Filler Cap

Remove the fuel filler cap and inspect the rubber seal for any cracks or damage.
Replace the fuel filler cap if it does not seal properly to prevent fuel vapors from escaping.

6. Reconnect Battery and Test

After repairs, reconnect the battery.
Start the engine and monitor for any fuel smell or leaks.
Use the OBD-II scanner to clear any previous error codes and check for new codes.
