Most models have a self adjusting hydraulic clutch.

The problem you have may be due to air in the system. Depends on mileage / age / model, etc.

Best advice for Megane owners: sell it before it bankrupts you!

rite its a 2003 with 59000 miles

how do i get the bite lower because it is undriveable now and sitting on the drive because of this problem dosent air in the system make it bite lower
also if there was an electrical fault would the bite be in the wrong place

and you say it is self adjusting how does it do this as i want it to adjust lower to the floor

any help would be really grateful
cheers

If the bite point is high, then you need to compress any air in the system more before the clutch releases (by pressing the clutch down further). If it hits the floor and doesn't disengage then you have a problem somewhere.

It is relatively easy to bleed on the 2003 car. Make sure there is hydraulic fluid in the master cylinder and that it is topped up to max. You have to remove the battery, tray, ECU, air cleaner and some ductwork to get to the bleed nipple. It will bleed with gravity once the nipple is open. Keep the fluid topped up.

If this doesn't cure it, you may have a problem with the master / slave cylinders, pipework or the clutch assembly itself.

I don't think that the problem could be related to an electrical system, but may be wrong.

I suggest you try the bleeding first as it can be done at home with simple tools (low cost solution). Unless you are a mechanic, the other issues will require expense.

Do the brakes work properly?

Someone else may have better ideas.

I agree with Dave. Whatever happens with the hydraulic system - change the fluid and bleed it before attempting anything else. Make sure that the floor mat does not restrict the movement of the pedal. The pedal needs to be pressed all the way in order to help the self-adjusting mechanism to do its job. The brake/clutch fluid, BTW, must be changed every second year, which is a characteristic of the fluid and not the car.

Jesus, no reply in 2 hours and you are bumping threads!?

DOT 4 should do it. You can buy it just about anywhere. Keep it in a sealed bottle as it is hygroscopic (it absorbs water) which is what Alex meant by the characteristic of the fluid. The water absorption is what makes it change colour. Never re-use old fluid for this reason. Also, don't splash it on the paintwork. It's good as a paint stripper.

No, sorry its the opposite. If you had "air" in the system the pedal would be spongy and the bite point would be too LOW!
The high bite point means the auto adjuster is at its limit and or the clutch polate friction material is worn .
I have owned a few Renaults where the bite was all the way at the top and just kept going.
Try handbrake on and taking off in 2nd gear! If it slips its kapoot, if it stalls, just live with the high bite point

The renault megane requires DOT 4 ESP brake fluid
