1999 Renault Megane Coupe from UK and Ireland - Comments

I have a 1999 (V) Renault Megane 1.6 16v Automatic.

When I atttempted to start the car (and on turning the key), the ABS + service light were lit, and the engine would not turn over.

I tried again and the same thing happened again, BUT then everything died. Now, when I turn the key nothing happens; the immobilizer light just flashes and I am unable to operate the windows and stereo. The display doesn't light up at all.

The key fob works fine; central locking opens no problem, and the battery is good. I recntly had a new starter motor installed.

Does anyone have any ideas before Renault rip me off?

Just bought 98 1.6 Megane - very comfortable, which is just as well as been sitting stationary in it quite a lot so far.

Problem seems immob fault as described by other folk on this thread (many thanks, I don't feel totally isolated now, though stranded up here in the Highlands means just that ie STUCK). Can anyone help please -

To "proceed" car seems to need to be relocked then unlocked again (from inside, once sitting in car, before turning on ign),otherwise it starts & runs for only a few seconds before cutting out. Once going, its fine until next time key is removed. Problem is that its taking more and more locking/unlocking key "aims" to "clear" it.

Im concerned about resetting codes etc as its very remote here & I'm worried I might end up totally stranded if I get it wrong!

Should I try renewing the key batteries or would that entail further complications?

Seem to have a "fuel incident" warning lamp on sometimes too, though lamba & Cat both replaced.

Any help most welcome. Cheers

Hi everyone/anyone.

I also have a 1999 Megane 1.6 with an intermittent fault. Most time it starts no problem, but now and again the engine just turns over and over.

If I leave it for about an hour, sometimes it will start. Question is - is this an immobiliser fault?

Does the engine turn over, but not start when the immobiliser is at fault?

Glad to find I'm not alone with the intermittent starting fault. My 1999 Megane has been doing this for some time now, with no apparent pattern to the times it occurs (wet or dry weather, whether been standing for hours or weeks) or how long it takes to fix itself. I think it could be the immobiliser resetting if I wait too long before starting the engine, but I don't understand whether this means I have to follow the given instructions to resynchronize, or get a new key (or get a new car???)?

Thanks.

My friend has a 2ltr RXE Megane 1998, and she is driven crazy with problem of the immobiliser. Is there any way to by-pass the thing altogether?? I would value any comments ta.. cathel.

Hope someone is able to help, I have a Megane Scenic 1.4 (2003) today the whole thing went mad all the lights came on, the indicators the windscreen wipers the dash kept beeping and flashing and the speedometer disappeared, it wouldn't switch off and even when I took the key out it continued for about 10 minutes, have tried this several times today and have the same outcome. Any ideas would be greatly received!!

Thanks.

Renault Megane 1999.

OK this is now driving me daft, I've been entering in the code for the last 2 months, thank god I don't drive that much. I did the stupid thing and went for the quick fix of getting a new key on ebay ---- it doesn't work!!! Looks like I'll have to give Renault the 150 euro for the fob. I hate thinking of all them times I've wasted seconds entering that code. If anyone finds a way to bypass it, please let me know, otherwise when I get rid of the car I'm going take out that ECU immobiliser thing and blow it up!!! I'll video it and post the link here, hopefully it will bring joy to the suffering of my fellow fob hating Renaultians.

I had the same problem as most of you guys. I have a megane coupe 1.6 1998, water had come in through the arial which stoped my key fob from working! I have now fixed the problem in under a day.

1) I called out the RAC because I could not start the car, if you fall lucky he will make a few calls and find the over right code for your car to start. Keep this code safe as you will need it later on.

2) next whe grey case where you point your at the little black bulb thing needs to be taken off. (The chip under this is what has messed up) when the case is off just pull the chip away from the connector, there should only be about 4 cables going to it.

3) Now you need to find a new chip, I got mine from a renault side street garage for £15 second hand. If you get it from renault themself its around £55 new. Change the chip over for the new one.

4) put key in and enter your over right code again, this time don't start the car up just wait for the red light to stay on to say you have done it right!

5) take the key out hold down your lock door button on the dash until you hear it lock x2 now point the key at the black bulb thing and keep the fob held in then press the fob 3 times!

All being well this should also work for you.

I don't normally do these comments so if you need anymore help or would like to thank me with money =p feel free to e-mail me at.

Good luck I know mine stressed me out.

I had the same problem.. paid 50 pounds for a code, then found out that there is a free code calculator on net.. just google Renault immobilizer test kit or this:

http://www.bba-reman.com/content.aspx?content=test_for_renault_key_immobiliser_failures_emergency_recode

It will work out your code for you.. also make sure the chip under the drivers/passenger light isn't rotten, otherwise you will need to get another one.. as I have just ordered mine.. (if your roof is leaking don't forget to fix it).

Don't go to a Renault dealer, cos they told me that I had to buy the full light/switch unit for 95 pounds plus vat (20 pounds).

Thanks. Hope this helps loads of people.

I have a Renault megane Scenic 1998 (S Reg). It has always started on the button. Past month I have an immobiliser problem. It's intermittent. Past two weeks it's been fine then today when I really needed to be somewhere it wouldn't start.

Same as others have mentioned on here - immobiliser light is flashing and the Engine Management Light is too.

Tonight I went out there to start it and nothing is flashing and it started first time.

Why would it not start this morning but start OK first time tonight?

What you do is go to scrapyard and get the circuit board, which is situated under the indoor lighting unit just below the sunroof. You can download your immobiliser code by getting the program off Google. Type in (renault immo test kit) then download the program. Then all you do is fit the new part and sync it to the key.. easy job. Took me 5 minutes. I got my circuit board out of a Renault Laguna, even though I have a Megane. So you do have options. If you need help, then contact me on gvmllr@msn.com Thanks.

Just get another chip from scrapyard, if you can't get a chip from a Megane, then one from a Laguna will work. Just follow instructions..

2) The grey case where you point your key at the little black bulb thing needs to be taken off (the chip under this is what has messed up). When the case is off, just pull the chip away from the connector, there should only be 4 wires going to it.

3) Now you need to find a new chip, I got mine from a scrapyard for 3 pounds (hard to believe).

4) Put the key in and enter your over ride code again. This time don't start the car up, just wait for the red light to stay on to say you have done it right!

5) Take the key out, hold down your central locking button on the dash until you hear it lock x2, now point the key at the black bulb thing and keep the key button held in, then press the central locking button in the car 3 times!

All being well, the central locking should now work of your key.

This post wasn't originally mine, I've just rearranged it so people can understand it a little better.. any probs email me at gavin_miller8@yahoo.com

Thanks for looking.

My problem is that the previous owner damaged the circuits on the key fob when changing the battery and as a result the fob won't work and can't be programmed!!

Is there any way to use a secondhand fob from another car to work on my car?

We have a Renault Scenic 1998 1.6 R reg which we bought about 2 months ago... the keys were working fine when we bought it, but then when we got it back and after a few days the fobs started to play up, and then last week they stopped working all together and would not disable the immobiliser to start the car... we got new batteries nothing... IR transmitter were not working either but everything was fine inside the key... we got the four digit code (which did not resync the key for love nor money) for free and have been imputing that since to our complete and utter exasperation. We did not want to give any money to Renault and my partner just this evening sat and took the key apart and was fiddling with it and making sure all parts were connected... voila... he checked the IR transmitter on the mobile camera and it was working... he quickly went out and... YES it is now working and the key is disabling the immobiliser again... how this happened and how long the key will work for is going to be a mystery that even Poirot couldn't figure out!! I wish we had never ever got a Renault, as if it happens again I will take a sledge hammer to the thing and end this battle for good.

From a very, very angry Renault owner.

I have a 2003 Scenic Intermittently it refuses to start first time sometimes taking anything between 2 to 10+ goes (NOTE: If the car is being looked at in a garage it starts every time as I found to my cost). If I leave if for anything between 3mins and a few hours it usually starts, last year it wouldn’t start at all so we called out the AA, a nice young man arrived (his first week working for the AA since leaving his last job as a Renault mechanic) he spent almost 1 hour working on the car and managed to start it. We had no problems for over 12 months and now the same old problem is starting to creep back.

Apart from ringing the AA any ideas?

P.s. The outside temperature display under the digital clock is showing a reading of 59! …..The greenhouse effect?
