Hi and welcome to the forum.
This message can indicate a few faults but the most common is a failed glow plug. If it's been plugged into a Renault CLIP diagnostic machine then this should have identified any fault codes.
A bit more about the car might help; age mileage, service history, previous faults etc...

Make improvements, not excuses!
