And by the way, I have notice that when the engine is cold, it start better when I wait a few seconds after the extinction of the preheat light. My glow plug have been changed last year and they have today about 30 000 km.

If i don't wait and start the engine just after the extinction of the preheat light, the engine run jerky during about 15s.

I know that the glow plug are still operating during a while after the extinction of the preheat light on the dashboard, but why need I to preheat my engine more than it is required ?
