Fuses and relays Renault Megane (2; 2002-2009)

Renault Megane 2nd generation was produced in 2002, 2003, 2004, 2005, 2006, 2007, 2008 and 2009 with hatchback, sedan, station wagon bodies. The sedan was assembled at a plant in Turkey, and the rest of the modifications in France. In some countries, the Megane 2 station wagons were sold under a different name - Megane Grand Tour. We will show where the fuse and relay blocks are located in the 2nd generation Renault Megane and how to get to them. Also, photos of blocks and diagrams with a description of the purpose of the elements, we separately note the cigarette lighter fuse.

The design of the boxs and the number of elements may differ from the one shown and depend on the year of manufacture and the level of equipment. The current diagrams must be marked on the back of the protective cover of the box.

Under the hood

In the enginene compartment of the 2nd generation Renault Megane there are 3 fuse boxes.

Battery fuses

This box is located on the positive terminal of the battery.


  1. 30A - Electronic control unit in the cabin
  2. 350 A - for a car with a gasoline engine, a generator, 400 A - for a car with a diesel engine - Engine compartment switching unit
  3. 30A - Switching unit of the engine compartment

Switching box

Installed on the left side of the engine compartment. Closed with a protective cover.

In one version, by removing the cover, you will get access to the block where it is possible to replace the fuse in another, the block will be placed in another housing and access to it will be difficult.

How to get to the fuse box under the hood 

First you need to remove the battery and unscrew the fasteners from its stand to get to the ECU.

Then we unscrew its fastening and move it to the side. We remove the air duct, near the radiator, and lift up the ECU holder.

In the block itself, wean off the bolt. And now we can push the block. Remember to unplug the power chips.
