This is the Renault electrics gremlin that's built into every Renault destined for the UK. Nearly every query about cars are about Renault cars, usually a nightmare to fix.  Best take it to a main stealership to get it fixed or you could try a local garage to see if they are prepared  to try to trace the fault.  Just type Renault into the search box, only 172 pages to search through.
