I have 2008 535xi 6AT, just replaced both turbos, turbo coolant & oil lines, and waterpump and thermostat.
My N54 has been intermittently overheating to which I believe to be the fault of the thermostat.
NOW before I go through the painful chore of replacing said thermostat I need to know; is the N54s thermostat unique to it, or is a thermostat for the N52 or N53 also shares its compatibility with the N54 as well?
Trying to distinguish a faulty thermostat to a non compatible thermostat?
