I read somewhere here that the preheating even starts when you unlock and open the door, then it times out if you don't start the engine.
The odd time I do get the glow plug symbol flash for a second or two! I usually hop in, foot on brake, key in, hit start...car starts automatically after a little delay when the glow plug symbol goes out! I've never seen an Idrive message, are you lci?
