Found some glow plug activation info. form a BMW TIS (posted here on Xoutpost by _chris_): -

From TIS:


At coolant temperatures below 25C, there is a preheating period of 0.5 seconds. The preheating period increases as the temperature falls, reaching a maximum of 2.7 seconds at a coolant temperature of less than -25C.

Activation of the glowplug system on the instrument cluster only occurs at coolant temperatures below 0C.


At coolant temperatures below 30C, there is a temperature-dependent after-heating period to improve idling and exhaust emission characteristics.

Start preheating

Start preheating takes place for approx. 10 seconds if after the preheating time has elapsed the engine is not started and the ignition remain on.
