Glow Plug Pre-Heating

Hi all,

over the recent cold weather ive been noticing that my dash throws up the glow plug symbol nearly every time i start.

I always take care to insert keyfob, press start (with foot off brake) to bring up all the warning symbols etc, then leave for about 30 secs before starting. I thought this was sufficient to get the plugs up to temp. However - most times when i then actually go to fire up the engine i still get the 'wait - preheating' message on idrive and the glowplug warning symbol.

handbook isnt much use, doesnt give any preferred methods.

am i damaging the plugs by starting the engine before they are up to temp?
