My parking sensors too don't work in my 07 Megane hatch.
It's the GT model so factory fitted.

Like Mr Pointy I looked in the dash fuse box but couldn't see anything relating to any parking sensors and couldn't see any fuses that have gone.

I guess my next job is to look in the engine fuse box which is a pain to get to.

Wondering though if the parking sensor control box is connected to the engine fuse box or not?

Also, does anyone know that on Renaults, if a sensor fails, does it shut down the whole system? On BMW's if there is a failed sensor, the warning tone just goes on continuous.

The reverse sensor taps the power from I believe the right rear taillight assembly. Check the rear tail light assembly, either the right or the left will have an extra connection.
Some aftermarket installation might have tapped the power directly from the reverse lights connection. Then if the lights blow , the rev sensor also fails. All this is provided your reverse switch is ok ( auto or manual?).

Thanks, I did take the nearside panel cover away in the boot and found the parking sensor module, also the alarm too was there. Power going to alarm but couldn't see where the power was picking up the module in the boot, so will try the offside.

Also found these in the engine fuse box

That was found when I removed the engine fuse box!

Also this plug was next to it

Again both not plugged in.

One I guess might be for the tyre pressure sensors, the other one?!

Couldn't see where they would plug in to either...
