I was instructed by a friend who had some of m47 and m57, to buy thermostat only original from bmw, because everything else doesn't work as long or good.
Pros: works long and good
Cons: other brands don't work
Vehicle:
BMW
I've got a 13 sport with 135k miles on it. Only ever done oil changes, spark plugs, 12v battery and a thermostat. Other than that it’s been stupid reliable.

The replacement thermostat came from BMW. No problems this time.

Noticed coolant was low and could smell it sometimes. Dealership pressure tested system and found coolant leak at thermostat housing. Thermostat replaced under warranty. Its probably been leaking slowly for a year or more.
Pros: replaced under warranty
Cons: coolant leak, slow leak
Vehicle:
Volkswagen Golf
Mileage: 27199 km
Independent mechanic noticed leak. Dealership confirmed the thermostat was cracked and leaking. Took a week for parts to arrive. Took a day to repair. All covered under warranty.
Pros: covered under warranty
Cons: cracked, leaking thermostat

I'll throw a lower temp thermostat see if I can get her temp to stay low as possible for now
Vehicle:
Volkswagen Golf
Changed to genuine thermostat, no change. Needle tends to dip on higher load highway driving, but only occasionally. Obd temp is between 77C-88C.
Cons: no change in performance, needle dips on load
Vehicle:
BMW
mine is also a problem an my car is 1.5 yrs old. Sometimes the temp gauge acts as if it is -40C outside even if it is a couple degrees above freezing. Often the car will take 4-5minutes to get near base idle when it is cool outside, but when it's really cold, sometimes it takes 30seconds and there is no way it's warmed up. Can also smell coolant anytime I open the hood. Sad.
Cons: faulty temp gauge reading, smell of coolant
