If anyone had problems starting last winter despite taking all the normal precautions, you might consider replacing the starter. One of my mercedes diesels always just seemed to turn over a lot slower than the other. And this was the case even though they had essentially identical batteries and clean cables.

A couple of weeks ago I ordered a bosch rebuild from Fastlane and I can't believe the difference in speed the starter turns the engine. The car now starts within a second whereas before it took 3 or 4 seconds even in warm weather.

I'm not sure I understand the failure mode that would cause this but somewhere I read that shorted windings can cause this. I don't know if you can detect this with one of the autozone type starter checkers or not.
