Top range with digi heater controls fail the same as normal controls.the resistor which controls heater speed burns out.I have done loads of these and the digi ones can be done by only removing the instrument cluster and undoing the 1 torxs 20 screw which holds it in.these are dearer than normal reisistors but the labour time of not taking out the dash is cheaper.(bet renault quote the same times tho).the digi ones do not have a modified wiring plug as do the other type. easy repair done in 20 mins hope this helps before winter.
