I have recently been expriencing problems when trying to start my Bmw 330 diesel. It continues to turn over but does not fire straight away. Sometimes it does start other times i have to get my jump leads out. No pattern either, one day it will the next it won't. Had battery checked and is ok.

In cold weather do you allow time for the glow plug light to go out
If yes
One or more glow plugs may have failed
