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 boxes are located in the 2nd generation Renault Megane and how to get to them. Also, photos of boxes and diagrams with a description of the purpose of the elements, we separately note the cigarette lighter fuse.
The design of the boxes and the number of elements may differ from those 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 unit.

Fuse 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 box where it is possible to replace the fuse in another, the box will be placed in another housing and access to it will be difficult.
How to get to the fuse box under the hood Renault Megan 2
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 box itself, wean off the bolt. And now we can push the box. Remember to unplug the power chips.
