Your engine has a BMW specific thermostat and housing. Not sure if what you want is possible without doing something custom. At any rate, the vehicle will throw a check engine light with the cooler thermostat. Guaranteed. The ECU recognizes a short trip versus a "permanently" too low a coolant temperature.

Yep was going to use an off the shelf thermostat bypass valve that forces all the oil to flow through the oil cooler all the time. It increases warm up by a couple mins but reduces cruise temps from ~110 to ~93. The vehicle will not throw a CEL with cooler thermostat installed.
