Have a look and see if it has glow pug type heaters in the cooling system. Diesel engines dont generate as much heat as petrol engines and need an additional heat method in cold weather. I think the glow plugs are suposed to come on when the coolant temp is low and after the engine has been running for 60 seconds or so. Connect your scan tool and check to see if the coolant temp sensor for engine is reading correctly. I dont know much more than that but maybe someone else can help. Best wishes Peter Cooper
