Exclamation Engine starts up in "cold start" mode 90% of the time

I've noticed over the past 2 months of owning my M3 that it almost ALWAYS goes into cold start mode after starting the engine. It does this 9/10 times and it doesn't seem to matter how hot or cold the engine is.

Has anybody else noticed this? In addition to this the car seems to have less power than if it doesn't do cold startup.

For anyone wondering what cold start mode is, it's when the engine is cold and immediately after the engine starts the RPM is high and the exhaust tone very raspy and loud. My car does this even when the engine is fully warmed up!
