Peugeot 107 Diesel Starting Problems:
Crucially diesel engines, being compression ignition, are affected even more by ambient temperatures. Glow Plugs raise the temperature of the engine block or pre-chamber to aid combustion of the diesel fuel (i.e. this heats the engine up a little making it easier to start). As the age of your car increases the Glow Plugs become less effective and fail to raise temperatures enough (or fail completely - in which case you will have problems starting and then have lumpy idling - and in the worst case it may not start at all). If your car is struggling to start, i.e. takes significantly longer to start than it should it may be a simple case where one or more glow plugs are no longer effective. A long term solution would be to replace all Glow Plugs for peace of mind (it doesn't usually cost much more to replace all the plugs rather than just the individual faulty ones as the actual glow plugs themselves aren't costly items) and will save cost over time as you're only going to need to inspect them once. Another thing to check is the Glow Plug relay, as this governs the Glow Plugs & if this fails they won\'t warm up.
Batteries: If your car is struggling to start it will most likely be the battery being in poor condition or in a poor state of charge. Being low on voltage the battery will have less crank ability thereby not turning the engine over sufficiently, the simplest way to test this is either with a multi-meter test the battery to see whether its in operational range or leave the battery on charge over night using a suitable battery charger. In the worst case scenario you may have to replace the battery, most suitable garages will know how to test a battery and most will do this for free and will advise on which car battery is best.
Some older cars may have an air leak in the fuel lines - you can ussualy prime the system on older cars (manually). Modern injection systems are often automatically primed and you will have to find the leak without testing so much.
