Why does my Citroen C3 Picasso go into limp mode?

I have a 2015 Citroen C3 Picasso 1.6-litre diesel that keeps going into limp mode and service light comes on. If I start and stop the engine five or six times it clears the problem for a few days but then the same thing happens again. What could be the problem?
Limp mode is a system that's activated to prevent engine damage when a component is faulty (and sends a signal to the engine computer to inform it of this fact). The cause could be a wide range of things, from a faulty sensor to gearbox issues. I would suggest taking it to a local garage for a diagnostics check. This should provide a fault code that will identify the exact nature of the problem.
