Mein Auto: 2007 335i
335i with check engine light coolant thermostat

my check engine light came on and I use a obd 2 scanner and it gave me the code P0128(coolant thermostat) Coolant temperature below thermostat regulating temperature. Any idea what's causing this? faulty coolant sensor maybe?

My bet is your tstat has failed and causing your engine to run under operating temperature. It's designed to fail open.
