Is this a 2.0 diesel? Is the engine management light on?

Just a update
Went for the mot yesterday and spoke with the guy
Who the put the old laptop on,malfunction in the glow plugs. Or the relay.
Thanks

Ah, it's probably P1351 - it comes as std on pretty much every HDi, but for Citroen / Peugeot doesn't usually cause any issues.

Thanks for the reply RichardW
Yes he said if its 1 glow plug it be ok but 2 would have problems starting in colder weather,
So will get it sorted in couple of weeks

Possibly there is a problem with the MAF sensor, the MAP sensor, the wiring/connections. Have a look at live data to see if the values are reasonable and the freeze frame data stored when the last fault code was given.
