Coolant leak is a good idea. I'll check the water pump area again. When your BMW had the thermostat issue, did it show any error codes, or just the overheating and slow warm-up?

In my case, there weren't any error codes pointing to the thermostat. Just the overheating and slow warm-up like you said. Considering what you've described and the mileage, a defective thermostat is likely. I'd still check the coolant system and water pump, but it sounds like a workshop visit is needed to properly diagnose it.

Yep, that was it. The map thermostat, just like I thought. Cost me 350€, but at least the engine's not overheating anymore. Thanks for confirming what I suspected!

Engine overheating is never good. I had a similar thing with my BMW 3 series, although mine was a diesel. Sounds like a thermostat problem. Have you checked for coolant leaks around the water pump? A failing water pump can cause overheating, but the slow warm-up does suggest the thermostat.
