What are the fault codes. Also it is still missing when you rev it up, the increased engine speed masks the missfire.

I would be looking inside the fan box as it is normally cooled by the air that is drawn in by the fan

what year.
find a diesel mech.
guessing is very expensive.
get a manual on you DCI, see what the light means.

its not that simple.
see a light, replace a part. not now, maybe in 2050
get the book only your DCI, and read up;

Not sure what your asking here as your english is more polish but i think you mean the cold start pre heater relay for the glow plugs or heater plugs and yes i have had this problem where the light in the dash is on but the heater plugs are not on and this just a warning light fault in the unit and is not a cause of loss of power but a faulty EGR valve will cause this so make a blanking gasket to seal the valve off and iam sure this will cure it -?-? but be carefull here with the diagnostics with these lovely french cars as a faulty throttle pedal control up under the dash will cause loss of power and lots of weird things with the engine light and the heater plug warning light ,these renaults are a rule unto themselves and although mechanically superior to most vehicles the electrics and the diagnostics leave a lot to be desired by this manufacturer

I have got those book in ebay in electronic format for less that 10 dlls, if you can not find them let me know I try to get it for you.

1.5 or 1.9 dci does not engage glow plugs until -4?C or below. so, check if fuel does not drain (in the morning). or if batery is week. try start with cabels (jump start) and see if start sooner.
another thong is if EGR valve always stays open (stick)
hope it helps

my warning light comes on saying "check emissions" and the manual tells me to go to my Renault dealer immediately. What is wrong? Can we drive the car normally for any distance

Check your plugs again, make sure they aren't gunked up already or covered in oil or anything. Double check the spark gaps on them as well.
