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

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

Mileage: 160934 km

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

Vehicle: BMW X4

Mileage: 61000 km
