Hmm. Well had to set off for work on tuesday morning at 4am. Slept in - typical. Went to start the landy and although it would turn over it was v slow and wouldnt fire the engine.
Not having any time to mess i took our girts car with a view to looking at mine later. When I got home it started first turn of the key. The only thing that had changed was the weather. At 4am it was minus 4 or 5 and by the time I got home it was warm and sunny.
I checked the battery and it was a little low on charge so i charged it back up and it showed full within 4hours. Put it back on the car and it fired up 1st go. The following morning it was about minus 2 and again it was slow to start. The battery is over 4 years old at least.
Gonna check the glow plugs this weekend. Any other ideas?
