Couple of things.

Drive along and take your hands off the wheel, if the steering wheel wiggles from side to side rapidly your wheels need balancing.

If the wheel stays still but the vibration is still apparent through the seat and pedals, then it’s the rears that need balancing.

Generally speaking though, if it stops when you hit the brakes or turn the wheel, you should also get the wheel bearings checked out. They create a vibration that is intermittant with cornering (i.e. vibrates round left corners, but fine round right corners) then it’s one of them.

If the speedometer is not working then it may be the speedo transducer that is at fault.
This is fitted into the gearbox just above the drivers side driveshaft, it can be seen from under the bonnet.
The connector that plugs into it has a habit of corroding and causing the speedo to stop working due to a loss of speed signal from the transducer.

The transducer can secured into the gearbox in one of two ways,
by means of a metal clip that slides in to the gearbox casing
Or the transducer has its own clips moulded into its plastic body and these hold it in place.

I think J G is right
Also newer Renaults will accept ‘Isofix’ (look for the label attatched to the seat.)

It could be the egr valve is sticking open occasionally, the tend to get gummed up with a lot of soot from the exhaust. Removing the Valve and cleaning it may resolve the problem otherwise it will be a case of getting it replaced.
How ever another problem with very similar symptoms is the variable geometry vanes in the turbo charger sticking ! This was very common on 2004-2005 models and would require a new turbo fitting to resolve the problem. To be sure what you are dealing with the best thing to do would be to get a diagnostic test done on the injection system, at least that way you know your money won’t wasted !
