Well Windyboy, you like many, many others before you have found to your cost that Renault electrics are c**p. £600 for a handbrake module to fix the problem, then, once that is fitted it will come up with another fault, more money to fix that. Cut your losses, take it to a scrappy, put the £600 plus your scrappy money into a more reliable motor, that means nothing French.
