It needs to be charged by a specialist. There they will drain the refrigerative and compressed air and inject an ultra violet dye and new refrigerant. Then when they pressuirse it up and test it they hold out a uv lamp to see if the AC is leaking and where from...... Then charge you £1000's to fix it!!
please tell me when you find the answer
Dunno for sure but there's a very useful explanation for lag 2 air con control unit light on Renault forum, with pictures! worked a treat for mine.
The gas seeps out slowly but you should have it refilled every couple of years
It is on the top righthand side at the back of the engine compartment.
At the Renault Parts website, you can purchase car parts such as brake disc screws, air con pressure sensors and bulb kits. For a full listing of parts available, visit the Renault Parts website.
what year is it? usually its the pressure switch located under the front undertray the one with pop rivets holding it in near to compressor unscrew it its on a schrader valve so no gas will come out, then go and get ripped off at Renault £107.00 for a new one! have the air con re gassed and cleaned properly then take your car in to Renault and ask them to re prorgram the ecu as this controls the air con not a relay, however by the battery and and tucked away is a fuse board you can see half a dozen or so large fuses ignore these and you will see a black sealed box above this contains more fuses its fuse number 2 if its blown but very much doubt it.......Read on if your gas gets low or pressure switch fails very very common on scenics it will send a signal to ecu telling it to stop the pump from working and the only way to get it turned on is by Renault and they charge £49 for the privelige
open the rear boot and pull out the spare wheel, then use a metal detector to search for the fuses as they get lost in there ,
the most likely reason is that the gas pressure is too low.Get the gas topped up at an AC specialist.
