i think this may be my problem ......ive already paid for the coroded wires being replaced but the guy didnt really help with locating how the water was getting there so i need this sorted asap also does anyone know if the megane cc have the same drainage tubes as u would on a car with a sunroof with the whole top being glass??

and also info on how to remove the carpets from the back seat area i can only get it so far from front seat the carpet :eek:seems to go under the back seats and with it being a convertable i cant see how i can remove the back seat to get the carpet out and dry underneath any help would be greatly thanked :)
First, I perceive the back seat footwells as an odd area to get water ingress. The front seat footwells, that's a known issue on a number of models.

That said, if it's anything like other Meganes or the Laguna, you should be able to grasp the seat cushion at its rear edge, and flip it up.
It's crammed in under the seat back, but should tilt forward with ease once it comes loose.

Also, not sure if there's a drain system going to the rear wheel arches, but there's one for the front, where the holes are in the scuttle panels below the windscreen wipers.
Poking them with a curtain wire (remove the end hook first) has been mentioned in numerous threads on these forums before.
Perhaps there are some similar drain holes below the rear window as well?

I also hav a water ingress problem, rained heavily on Monday, pushed my stop button, took out key card and my wipers were still going and the engine kept trying to start itself....

The only way i got it to stop was to disconnect the battery, the drivers footwell is soaked, i need help !!!

Car will now not start (after reconnecting the battery, and still has life of its own until battery dicsonnected)

I have cleaned out the drain beneath passenger side, but have been unable to clear out drivers side.

Anyone help me please

The tubes mentioned in many threads are for teh area around the sunshine roof; tubes run down the A and C pillars into the wheel arches, to allow to escape any water that makes its way past the edge of the roof. These tubes often get blocked, hence the threads how to unblock.
For teh CC, with a single piece glass roof, there will not be any such drains.

The scuttle drains (under the plastic cover, below the wiper blades) allow water running off the windscren to run into the front wheel arches. Renault fit a rubber flap in teh hole, and these tend to get gunged up, and so stop the water escaping. Clear teh flaps, clear teh water, clean the edges so the flap does not stick, and the possibility that a lake of water would collect in teh scuttle and enter the car through the air vent is removed.

In teh case of teh CC, you will have many other places that can allow water in; unfortunately, every car will be different, and so you will have to develop a set of techniques to find them.
1. Dry area, and then use talc to detect the fresh flow.
2. Be inside the car and get someone to play a hose over each area in turn, to work out the leak. (Start at the bottom, and work up each panel and joint in turn. Try to keep areas that have not yet been investigated dry.)
3. Inspect teh seals and confirm that they are sound, uncreased, have no wires impairing the function, etc.
4. Be aware how you park the car, to see if the run-off makes a difference.
5. For the short time it takes to find the problem, take out the (spare) seats and carpets, so you have dry access everywhere, and can see small amounts of water.
etc.
Happy hunting.

For details, please identify the car...

Sounds like one of the controllers has become soaked; you may be lucky enough that it will dry out, but probably you need to clean it and dry the connectors. Clear out any corrosion on the pins at that time; it is the false signals that allows the car to keep operating once the key was removed.
But, given the controller is tucked out of the way, there will not be many ways the water can reach it, and this will simplify the search forthe leak.

Not quite sure what you mean by "the drain below the passenger's side"?
If you are dealing with the sunroof drains, you would have water in the groove around the sunroof, which cannot run away. Go into the back of the front wheel arch, remove the screw, and the drain tube should be visible there. Pull the cap off the end of the tube, and ensure the tube is not blocked. Repeat for the other side.
If you are dealing with the scuttle drains, these are below the windscreen, and whilst each side has its own challenge, you can typically get to them even without removing the wipers.

Happy hunting for your leak.
