I had same Problem with 03 Megane about 6 weeks ago
and the fault on mine was the one of the Coils had gone.
got replaced £270.00 later working fine....

just happened again with same message Check Injection.
RAC told me injection has gone, so now yet again back in the garage.. How i wish i never brought a Megane

SOURCE: zigzag light on megane scenic dashboard comes on

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

I have 2 meganes im working on at the moment both have the same problem. the electrical falt light is on coz the pipe has snapped (or come off) under the bonnet on the passangers side close to the window (theres a black box about 2 inch wide the pipe connects underneath). if I reconect the pipe and grab the engien with both hands it wobbles and the pipe pulls off. I suspect this is coz one (or all) the engien mountings are shagged. and this will be the cause of the juddering when driveing in first and second gears. solutions iv have come across for juddering involve changeing the coil pack but thats nothing to do with the problem my 2 cars have as one of them has new coils. they are 1.6 petrol, p reg and s reg
