During the recent cold spell, my car took some serious turning over before it would start. So I looked into it a bit further and I found that disconnecting a glow plug reported an error on the dash. So assuming everything is okay, as I get no errors when I don't intervene how long do you guys leave the ignition on before attempting to start? To my surprise there are some very small cables to each glow plug, maybe 1.5mm at best? My older cars had huge connections to relays with 6mm wires and they always started after 2 seconds at worst? Anyone's thought would be appreciated!
