Its possible the glow plugs when its warm the diesel is warm and starts more easily when its cold the diesle needs warming more so the glow plugs work harder in the winter only way i know how to test them is to take 1 out at a time turn the pre ignition on so the glow plug light comes on and the plug should glow red if not buy the 4 and replace the lot you could also check the wireing going to the plugs hope this helps ivan

Sounds to be a loose or corroded wire/s at either starter motor or at battery fusible links.
Also check the earth strap (Cable) between engine and bodywork.
Hope this helps, MMP

Your fault need identification after the vehicle is parked for a long time. The nearest possible area of doubt is the condition of the engine. You have not specified the mileage clocked and the regularity of periodic service because if this is done systematically there can be lesser areas to look for in our trouble shooting solution. Hencce to start with your fuel pump, the fuel filter and see if the fuel drains off inthe fuel system when parked for long time. If so identify whether it is in the fuel system or the pump. If fuel seems fine, the engine compression, valve setttings must be in order for a quick start. If this shows good reading, asssesment of the compression of each cylinder by a test of the pressure of air exhausting in each of the cylinders is good. If this looks ok then check on the to the actuator or the auto choke valve. If possible drain off/ run off your fuel and try a different higher grade. I have the feeling that the fault could be the firing or the fuel both of which you can check on alternate days before starting( for petrol check your plugs, your HT coils or replace, for diesel check your glow plugs and replace if bad or worn out ). Hope I could assist. Good day

Possible weak battery faulty starter or relay. Start by checking & charging the battery & making sure the connections are tight & clean. Check charging system too.

Hi
It sounds to me like it could be a glow plug fault !
The glow plugs heat the diesel before it combusts. An easy way to diagnose this is check your exhaust after cranking on a cold morning if you have thick white smoke then you've probably got a glow plug down on 1 of your cylinders or maybe more
Hope this helps Nick
