This has been a constant issue for me even during summer.
I have a 2004 1.9 CDTi SRi 120.
In the cold the issue gets worse and tonight leaving work I was worried the battery was going to drain trying to start it. Normally when its chilly it takes a few turn overs to start, enough to hope no ones looking lol.
Beginning of the year the battery did die and I replaced it for a brand new one, That night i got a jump of my old mans Land Rover who kindly came to help and it started straight off the bat, this made me assume as that before I sorted it out, the car had been sat up my dads farm and hadn't moved for a year so I assumed the battery had just expired from idle.
For a while it was ok and then as it started to get colder the issue came back and it was struggling a little to start. As it gets colder the issue gets worse. Once the car is started if I leave it for a few min and come back to it it will have no probs starting again, its just that initial start from cold. I have a few theories.
- Glow plugs may not be heating up to the proper temp?
- Battery may not be recharging properly and fault with the alternator?
- As I dont travel very far I dont know if it may the case that i'm slowly running the battery down with short trips, though I doubt it, how long does it take an alternator to recharge the battery after a start? I doubt its long, but the idea crossed my mind.
Any ideas or suggestions would be greatly appreciated. My first thought is no.1 and I did look at changing the plugs but it looks an absoloute pig so may take it to my mates garage.
