Cruise Control Not Working

The speed limiter works fine.

When I flick the rocker to cruise control the digital display changes to:
Cruise Control
--mph

So all looks ok.

But the + button doesn't set any speed, and no other steering wheel button does anything.

What should I look at? Clutch/brake switch thing that would turn it off? As that wouldn't affect the speed limiter, where are they?

Other weird thing is I can't set 66mph on speed limiter lol when pressing + it goes from 65 to 67... weird.

Any suggestions?
 
If none of the buttons work Id suggest there may also be an issue there? Broken wire?

It's the switch under the clutch pedal. It gets stuck in the down position, which messes with the cruise control only (which works off the switch). Doesn't impact the speed limiter. I had the same issue, and apparently its a common problem. You can pull the plastic switch out and grease it a bit to get it to move more freely again, or replace it. The dealer fettled with mine and its been working fine for another year, knock on wood.

As for the numbers, yea, they only go up by 2 unit increments in KPH as well, so I guess thats a programming thing?

Thanks!! I'll get that done at the weekend.

Thats really weird, I went to set it to 66 the other day and couldnt. 275 megane doesn't do that
 
Had a quick look when i got home, when the clutch is fully out (not pressed) it seems to just come up to the switch. But it doesn’t push the switch in. I can push the switch in and out with my finger.

If i hold the switch in with my finger and go to cruise control i still can’t set a speed, but I dont know if that is because im not moving.

Probably hard to make out the picture, but this is the clutch fully out (not pressed) and it just comes up to the switch but doesnt press it.

I think the switch is supposed to be fully extended out when the clutch is also fully out. Mine was stuck down, so the ECU thought I was on the clutch which disengages the cruise control.
 
I took it out today. Couldn’t understand how to extend it. Took the switch apart and everything. All you have to do is pull it hard and it clicks out haha. Was scared of breaking it. Didn’t even have to take it out of the car. All works again. Thanks everyone!

Happy to help, glad it's fixed mate.
