SOURCE: renault megane cabriolet roof broken?????

just had the same problem with mine, here's what the problem was, the hydrolic fluid had gone bellow the min level indicator because of a slight leak to the ram, the reservoir is located in the back N/S boot. refill the the reservoir (Halfords do the hydrolic fluid for them) then you need to re-set the roof mecanism, after opening and closeing the back part of the car where the roof goes manually, and trying the switch a few times to reset the locking device with the micro switches, I managed to do it without spending too much cash. hope this helps anyone with roof trouble. -

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
