Anyone had this issue with thermostat?

syfotoz · 11-17-2021, 11:11 AM

Hi all! Picked up a M2C in June. Recently just crossed 2300 miles. Just had a casual outing running errands and turned on the car. Check engine light came on. Brought it into the dealership and turns out it needed a new thermostat. They replaced it under warranty. Didn't expect this happening so soon since its so new with low mileage. Anyone else had similar issues?

It's not uncommon for the thermostat to fail on the N55's at high mileage but it is pretty rare for it to occur at such a low mileage like your car.

When it fails so soon it is indicative of manufacturer defect. Happens to anyone.

Sticking thermostats are a 'feature' of many BMW...

Especially as time goes on.

Mine was stuck open at same mileage. Somehow it leaked and ruined some wiring harness.

Hey everyone. 2018 F87 M2, 26k miles I just got the check engine light for stuck open thermostat. I cleared because I “accidentally” did a few pulls before realizing I didn’t fully warm up the engine. Plus my radiator was just reinstalled after replacing my broken A/C codenser. Any idea if I should change the thermostat or wait to see if it pops up again before?

To note to this my oil temp is just where it should be ^^ Reason why I believe my DME was confused the engine was accelerating and the thermostat opened so the hot and cold coolant mixed
