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

Most likely to be a faulty resistor block, which has 3 resistors and a thermal fuse controlling fan speeds 1,2 and 3, maximum speed 4 by-passes the resister block. It may also be poor electrical connections to the resistor block caused by overheating. Renault ask for approximately £350 to carry out repairs, a replacement resistor block will cost £50. If you decide to carry out the repairs yourself, be advised that if you are not competent to carry out such work you, could cause electrical damage or worse an electrical fire.

this exact problem on a megane coupe is caused by a small air pipe that connects to a 2 inch wide black box that is located under the bonnet near the windscreen on the passangers side. the zigzag light indicates an electrical fault (in this case lack of compression and will affect your revs) if you find this pipe and it has snapped off. the reason for this may be that your engien is lose and moves. grab the engien with 2 hands and see if you can wobble it with allot of play. if so your engien mountings need replaceing. you may also experiance juddering in low gears
