Parts required:

* 82 00 079 020 - Surround switch (£7.42 from renault)
* 82 00 193 673 - Blank switch (Plug- £2.70 from renault)
* 82 00 107 841 - CC/SL switch (£15.75 from renault)

Image

Image


Optionally not needed if you use another four push-buttons for controlling CC
* 82 00 103 769 - car radio remote control (I bought a used on of these off ebay)
Image

And from a electronics store, maplins-expensive, so preferably other..
*900ohm, 270ohm and 100ohm resistors (16p)
*half a meter of speaker wire (15p)
*solder and soldering iron (i alredy had these, i have a gas soldering iron as i find it easier in a car as you dont need extension cables, these are around £20)

From a diy store, for fixing the control in place, glue and optionally black silicone sealant.

And that's all you need.



Once you have all these parts your ready to go!

How to

Step one: You should swap the new parts from renault with the old ones, this is simple, like lego...lol just literally swap the cover and add the switch and blank switch and plug the new switch in..

Image
-this isnt my photo but it shows what to do, but like ive said its like lego, youll see what to do when you remove the old and have the new there to compare..

Step two: Now I prepared the control, I chose to not modify the sterio control and so have function of increase speed, decrease speed and recall,its fine as you can cancel the cc by depressing clutch or brake..

Below are pictures, and diagram.
(Taken from Kmarty, thanks)

Image

Modry = Blue
Zeleny = Green
Cerveny = Red
Hnedy = Brown
On the bottom of that picture are colors of wires in connector under steer (but they can be swapped):
Ruzovy = Pink
Hnedy = Brown

Image


Its very simple,
1,you solder the resistors to the control as shown,
2,solder the other ends of the resistors together and solder these to one part of the speaker wire
3,solder the other part of the speaker wire to the control as shown,

These are my photos..

This leaves the other end of the speaker wire free and untouched.

Step three: The next step is to remove cover from around the steering wheel, there are 3 screws and then another 2 screws..
please see picture.
Image



Step four: Now you find the two circled wires and carefully skim away some of the coating to reveal the copper, now the until now untouched end of the speaker wire. solder one part of the speaker wire to one of the wires and the other part to the other,
Image

Please see photo.

Thats it, now the cc should function :)

Step five:the next step is to cut a slot in the steering wheel cover to allow fitting of control, see photo
Image

Now in mine I have glued the control in place and filled the gaps with silicone sealant.

Job done,

Im also getting some transfers printed so I can label the control correctly as cruise control as I removed the print referring to stereo control.


Hope this is helpful, let me know if you need any advice... Im here to help!

Big thank you to every one who has provided me with info to do this, wouldn't have been possible without your help!

Dnno if this is in the right place... Maybe wothr going in the megane article section??

Gret thread, just what I was looking for..

However, on my 05/55 Grand Scenic Dci Priv, I don't appear to have the connector for the cruise "on/off" switch, ie the one on the same panel as the instrument dimmer/headlight adjust..

Does this mean I don't have the facility to fit this?

Hi , first of all thanks for all effords. I can get the big picture but there's a point that i cannot understand.

As shown in the table ,
Image


but it's not clear for me that 3 resistors wired to white speaker cable , and the other cable to red cable.

like this;

Image
which is true actually.



This is the matter that i can't solve. Helps will appreciated. Have a nice day!

For what it's worth - I wanted to test this before hacking up my steering column, and I couldn't find details on the white connector (by the headlight adjuster).

You'd need to use a on-off-on latching switch, and the pinouts of the connector (looking from the bottom) are as follows :
Code:
+--+--+
|##| C|
+--+--+
|  | X|
+--+--+
| L|  |
+--+--+

Where ## is the missing pin, X is the common wire, C 
 is Cruise Control mode, and L is limit mode.
Also, for what it's worth, it all worked, and I went down the 'extra radio stalk' route, but I decided to stuff all the resistors into the stalk, and snip some tracks. My stalk (mounted on the opposite side to the radio) has Vol+ as Speed-, Vol- as Speed+, Mute as Restore, and the top and bottom buttons all as Cancel).

£10 in a local breakers for a spare radio stalk and a handful of resistors later, and I'm very happy (apart from the lack of daskboard lights - but I don't have a clip, and I'm don't want to pay £100 for the privilege). Is there an easy way??

On thing I did notice though is that the speed limiter 'kickdown' function doesn't appear to work - it doesn't matter how hard I stand on the accelerator, it won't budge over the limit unless you disengage SL.

could you not use the correct cc control as this would fit directly onto the back of the clock spring. Just 2 screws. would the connections be the same as the ones shown.

The loom should be vehicle specific hence having all connections for all extras, if i am correct.

not off till the weekend so will have a look into this...

Nice thread for retro fit...

Hi What a Great thread read all the way though just wondered if this will work on a MK4 espace, Going to have a go on the wifes scenic II first. I like the control switch set up will save a fortune on parts. :d

Re: Megane cruise control, retro fitted, how to guide

Do you know if I can use the resistor set up on my grand scenic II, it has a place for the on/off control under the indicator stalk rather than next to the headlight aim adjuster, but if the wires are there guess should be almost the same??

It works on the espace I try to put on some pics and how to as soon as I get chance

Hi guys thinking about fitting this, once ive paid for new engine mounts. Anyhoo what happens in the situation where you have an accident (enough to activate air bags) with cruise control/speed limiter enabled. Will it be able to shut it off like standard? If not i think ill avoid it. Ta :)

Hi Joeishmather,

I've just bought a Megane 3 (2011) its been suggested the wiring to add cruise may be already in place, any idea if that could be right?

The switch sits in the handbrake console, mine has a blank fitted and the controls are on the steering wheel.

Am I being somewhat naive in hoping that I could simply fit the switch and change the steering wheel, make the connections, if the wiring is in place, and job done??

This seems to be the only thread I can find regarding retro fitting CC, although its an old thread.

Many thanks,

Mart

Im rather confused as to which bits exactly i need..
Im okay with the cutting and soldering and gluing etc, but i cant get to grips with which wires to select and where they go to... could you tell me the part numbers ill need to do it using a stereo controller like is already behind the wheel?
