The gasket looks fine. Normal procedure would be to buy a new one from BMW. always go OEM with the thermostat, there's a lot of shit knockoffs.

Cons: shit knockoffs

Your thermostat is probably stuck open. Replace it with an OEM Motorcraft version, not aftermarket.

Pros: OEM Motorcraft version

Cons: not aftermarket

I recently moved on from a 2016 X3 35i (N55) with a little over 100k miles on it. The only things to break on it were the thermostat and a control board for one of the headlight modules. When I replaced the thermostat I did the water pump as a precaution.

Pros: only consumables

Cons: thermostat broke

My 535i with the 740d thermostat sits at 90-95 during normal use, even sat stable at 95c during 40c weather in traffic. When beating on it in the mountains got it up to 99 at like 28c ambient.

Pros: stable 90-95c temps

I have this exact engine and installed a diesel thermostat. Previously, with the standard thermostat, the plastic timing chain guides would start to disintegrate after three years, but now I have no problem with that. The engine temperature is around 96°C.

Pros: no guide disintegration

Cons: guides disintegrated (standard)

Notice the radiator is leaking. Replace that. Car still not happy, cooling fans on full blast. Codes point to a thermostat, but the radiator hoses get warm. In my pea brain thermostats don't normally just sometimes go bad, they're typically either all broke or not broke. Ordered a thermostat from Trumplandia anyways.

Cons: expensive, complex design

I bought a 2022 X4 about a month ago from BMW. Had it for 2 weeks and got the same notification. Took it to BMW ( I got the warranty) and adjuster came in from the warranty people on Monday but haven’t approved the repair yet. They said it was also a thermostat. Seems like this is a common thing in these cars ? Mine is at 61k miles, bought it used and only had it for 2 MF weeks.

Cons: thermostat failure, common issue
