Will try the suggested remedies - More odd conditions to bring up behaviour

So, I've now found out that the following conditions need to be met in order to reproduce the issue:
- Ignition must be on (Engine doesn't need to be running)
- Headlights or sidelights must be on
- Right hand indicators must be activated
(Hazard switch won't do it)
- Brake pedal must be stepped on

Once all four conditions are met, the issue occurs.

have done the usual disconnect/connect the light cluster it cures it for a bit then comes back after i use the fob to lock it up.
That's odd… unless the wiring loom for the cluster only has three wires, and there's a chip in the cluster
which communicates with the UCH in order to control the lights (someting I find highly unlikely):
- +12V
- Ground
- Data (maybe bi-directional, in order to report faulty bulbs?)

A good clean up with some fine emery and a blast of switch cleaner may help.
This is a fairly common problem and not just on Renaults might I add
Electonics contact cleaner should work fine. If not, have the wiring looked at, in case it's dodgy.
I'll be looking at my right hand cluster once I have the opportunity to do so.
