E92 takes 30 mins to warm up, need help.

Although I'm not new to BMW and the fanatic forums, I am new to the E9x chassis. I'm writing on behalf of my father whose 2008 E92 328i takes a very long time to reach operating temperature (the water temp gauge to reach about 230 degrees F). It seems like it could take anywhere from 20-30 minutes to reach operating temperature, which sucks considering its average commute is about 30 minutes as well. By contrast, my E46 takes 5 minutes tops.

Is this normal to E9xs? I just hate to think the car always in cold start mode, getting awful MPG while spending a large portion of its mileage below op temperature... very bad for engine life, I presume. Has anyone had similar symptoms? What are the causes and remedies?

Thank you all

Can't speak to any specific E90/92 experience but that does seem something's wrong there. My guess would be the thermostat. It may be sticking, not allowing the car to warm properly.

Purely out of curiosity, what is the outside air temperature when it takes 30 minutes to reach operating temp?

During the winter months, I noticed my 330i would sometimes take an abnormally long time to reach operating temp. This was compounded by me driving for a long uninterrupted period, with no stopping. As soon as I would stop, I would often times see the temp rise to the center rapidly.

What does it mean if a thermostat is "sticking?" Does it mean that the engine does not recognize its own temperature accurately?

In summer, the car does its work in anywhere from 70-90 degrees F. Winter mornings might be as cold as 55. The symptoms I'm describing have been happening for a while, all seasons/temps.

Thermostat "sticks" open allowing antifreeze/water to circulate. The thermostat is supposed to stay closed on a cold start up and open when the engine hits the appropriate operating temp.

The thermostat is design to fail in the open position, so that the engine doesn't over heat and cause even worst issues.
