My megane coupe judders

I have a 1997 1.6 megane coupe. i started the enfine one day and it was juddering like a spark plug had gone. I took all plugs out and cleaned them put them back in and it worked fine. about 10 miles later i stopped pulled up and when the car restarted same thing happened again. clean sparks and it ran fine today. what caused this or is causing it. the plugs are quite new. my temp display is not reading correctly the sensor is away. could this cause the juddering by over feuling causing the plugs to get messed up

My engine light started to flash orange on my 03 renault megane. the car also began to judder. I have been experiencing problems starting the car and think this may be connected


I have a 2000 megane and have had a problem like this a few times in the past. In each case, the problem has been due to a broken coil - this has a separate HT coil per spark plug, fitting directly onto the spark plug, and the coil breaks, so that the plug doesn't fire and the engine judders. I think the light is because the engine management notices there is unburnt fuel coming out.

I'm told there was a known flaw in the design of the earlier coils, but it's supposed to have been rectified. But I've had a newer fail, and now carry a spare. Easy enough to fit - tricky part is identifying which one has failed - can remove one LT connection at a time to see if anything changes - I've always stopped the engine between tests rather than doing it live. This might be bad for the engine - I don't know. I was told you should replace coils in pairs, but don't know about that.

But I guess it could also be a break in the LT wiring, or a fouled spark plug. Or something else entirely.

Scenic megane 4 yr old, 13K miles, just had service,


Hi
faulty spark plugs is that the garage/dealer/mechanic said to you ?

Sounds like to me a ignition coil, and your car has 4 so this could possibly mean in the future more visits to the garage, to be sure I can suggest taking off the top engine cover and see if you have 4 grey ignition coils, manufactures name SAGEM, also now factory replaces with black coils.

Renault megane engine light flashing and car is juddering.


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

Renault Megane Coupe-Cabriolet juddering problem Renault Megane Coupe-Cabriolet juddering problem i have a late 2007 model the juddering only starts when i have been driving for an hour in slow traffic...


Your clutch is either wet with oil , or you are riding it oo much and making it hot. Push it all the way in when you are stopped. Don't hold it part way, or you will burn it out.
