1999 Renault Megane Coupe from UK and Ireland - Comments

I've had a Renault Megane 1.6 RT on 'P' plate for over 2 years and had very few problems with it! However, it has been left stationary for about a week because of no tax. I turned the engine over yesterday when I was cleaning the inside, the battery seemed slightly low, but nothing too bad. I came to start it up today to go and get my tax and it won't start! The battery is now low, but the immobiliser won't disable so I can't start it up at all. It's strange that both the petrol and temperature gauge both go to max when I first turn the key, and I can hear a hummming sound from the immobiliser before it starts flashing again.

I've read the comments and it seems like it could be a damp immobiliser problem... I've never had it before

mat.

Has anyone had a problem with the electric roof of the Megane Cabriolet 1.6 sport? (2002) I purchased the car 2nd hand with 10k mile on the clock, as it was winter I did not need to lower the roof, alas in summer, it was pretty bad, sometimes it worked, others it got stuck either halfway up/down, and just transmitted a blipping noise, took the car to my Renaults dealer, who checked it out and declared that it was something to do with the switch, Renault paid something towards having it fixed and I paid the rest, OK for the rest of that summer, summer 2004 it was as bad again, not being in the position to keep coughing up for this I just did not drop the roof - shame when that's the reason I bought the car in the first place.

As summer approached again, I have now booked it into my Renualt dealer to once more look at and hopefully repair.

Anyone else having had the same problem.

Having the same 'starting from cold' problems with my 'T' reg Megane 1.6 16v. Sometimes it will start first turn of the key, sometimes it takes 30seconds or more of turning. I have been advised to check the TDC Sensor connection. Everything else appears OK and I have given it a full service.

I too have recently been faced with a problem regarding my immobiliser. Last week the key fob wouldn't work to turn the immobiliser off, I had my batteries in both key fobs changed yet still no joy!

Through talking to a mate he has informed me that the receiver can get damp and cause the immobiliser to pack in until dried out! Can anyone tell me if they know how much it will be to get this problem fixed and do I need to take it to a Renault dealer??

This is very frustrating for me right now as its taking me at least 15 minutes every morning to be able to switch the immobiliser off.

Hi.

How do you switch your immobiliser off on the MEGANE COUPE? I've got 98 edition and the TDC sensor has gone and I can't start the vehicle.

My immobiliser packed in on my Renault Megane Coupe, so I took the receiver unit out, which is in the headlining near the rear view mirror, and dried it on the radiator, and as if by magic, it works now. If you don't have a radiator to hand, spray it with wd40, that works as well. It's a common fault on Renault Meganes with a factory fitted sunroof. Water leaks in and stops it from working. Hope this helps!

Been banging my head against a wall, have read all similar problems posted. I have a 99T reg Renault Megane 1.6rt, and yes have been experiencing the erratic starting problems that seem to be quite regular with other owners.

I can start the car no problem one day, then the next it can take 2 or 3 times continuous turning to get the engine started. I have noticed, and this is just an observation, that for some reason when the car fails to start, the odometer resets itself, strange, but I wonder if an electrical problem the culprit. Anyone who has any new ideas, please share your info please.

I had the same problem that many people have had with starting my car, a Renault Megane T reg. I solved the problem by removing the TDC sensor, and cleaning it with a dry cloth and removing and dirt from the TDC and electrics. This took me about 5 minutes replacing the TDC, and all worked fine, not forgetting to remove the negative lead to the battery first.

I take no responsibility for any problems that might be caused by doing this; this is done at your own risk.

I have just bought a W registered Renault coupe 1.6. I am very pleased with the car except a minor problem. the sunroof won't open!

I have a 99T Megane Coupe Sport, and now the summers here I found my electric sunroof doesn't open properly either. It actually got stuck Ttilted open, then when I finally got it closed (no I didn't use brute force just jiggled and coaxed it carefully), I find it now only tilts up on the drivers side and not the passengers, as the motor makes a horrible noise I now haven't bothered trying to open it again..

Has any one else experienced this? I'm not sure if a lifter or cable has broken on it? Anyone who may have a clue let me know.

I persume everyone else with one of these cars now gets the customary clicking noise when they first start the car now too as the little cog behind the dash which adjusts the duct vents has broken too?

Nice looking car, shame about the french build quality huh...

Megane ignition failure:

Is your starter-motor running, but will the engine not start, please check your Hall sensor on the top of the gearbox, this sensor creates the window in which the ignition should take place, it is a well known problem for these cars, I found lots of examples on the dutch Internet referring to it. I replaced the sensor on my car myself (10 minutes job, only unscrew 2 pieces M6 bolds) price is about 26 Euros.

The garage can check your Hall sensor, if they repair it the costs will be around 80 Euros.

Success, regards

Have the Immobiliser problem on 97 megane, where it won't disable. There is a band-aid solution: Check inside the key (unscrew the cover) & note the codes down. Phone Renault dealer & describe the problem - they will give you the immobiliser code for your specific car (well they will in Ireland anyway). You can manually enter immobiliser the code by pressing the manual central locking button; works every time. Tried taking out the immobiliser fuse, but the relay seems to default to 'engine disabled' position, as car won't start. Does anyone know how to totally disable the immobiliser permanently? If you do, please post.

I have a p reg megane coupe and I'm having problems staring the car. The immobiliser is fine, but the engine won't turn over.

I also have problems with my air reconcycling system which constantly ticks and I have to keep it on to avoid hearing the annoying sound, can someone please help me here?

I have a R reg megane coupe sport, I have recently had to get towed home as my key fob stopped working and I couldnt start the engine as the immobilisor disabled the engine, I have just ordered a new key from renault under advice from the AA man. the key wasnear to £130 and it takes like 2 weeks to come so I'm car less, my spare doesn't work either so I suggest if ure spare doesn't work you be careful incase the other packs in and ure stranded. is there a way to disable the immobilisor just to start the engine to get it to the garage to tune the key in???
