Hello Joaquintomas.
There are, as in the rest of the things, 2 ways: 1 the easy and 2 the difficult. The bad thing is that I don't know which one, if 1 or 2.
(1 or 2, I don't know!) I have changed the lamp on the left side several times. It is not difficult, it takes 10 or 15 minutes in total, but it depends on your manual skill. You will need to remove the battery lid, remove, at least a little the battery if you do not want to remove it from the car, remove the cable connector that passes between the battery and the fin, and loosen the air inlet tube to the filter. With that you already have access to the lighthouse. You have to first get the ballast and, finally, you can get the happy Xenon bulb.
(2 or 1, I have already told you ...) This is the official Renault system, and as such I describe it. It takes much longer ... but sometimes the dress me slowly, that I am in a hurry ... you have to value it. I also attach a file to see it better.
You have to remove:
-The lower protection under the engine,
-la Calandra,
-The front bumper,
-The two upper guides (under the lighthouse, between body and bumper),
-quite the screws that hold the lighthouse plus a plastic clip.
With that you already have the lighthouse in your hand and you can change the lamp.
Luck!!
