Thread: 2.4 tdci Puma cuts out when cold idling

2008 'Puma' defender 130. Unless in a particular hurry, I run the engine for 5 minutes or so before driving when cold; e.g. while I gather my gear for work etc. Yesterday morning after working night shift, I started the engine and left it to idle for a few minutes while I got changed and gathered my stuff to come home. Came out to the car and it had stopped. Started it up again while I went back for another armful of stuff, came back out and it had stopped again. This was after sitting outside overnight, not a particularly cold night. Also happened one time the previous morning while preparing to leave for work at about 5:10 a.m.
It developed this habit about a year ago, then hasn't done it for a long while. Last year when it was happening, the vehicle actually cut out while driving when cold on a couple of occasions if I had not warmed it up.
I haven't had a chance to read the fault codes as yet, but wondering if there is a particular sensor or something that will cause this problem.

Thanks for that suggestion, probably not something i would have thought of.
