I searched through this forum, and through Google, and nothing. There is no bleeder on the thermostat housing, and no bleeders on any of the hoses that I've traced.
So what gives? How do you bleed the coolant system on the N18?

A Bentley manual will be helpful for lots of your future projects. Otherwise, I believe this tech article should be relevant as it states at the tophere (9th paragraph from the bottom). I did find this thread here on NAM about bleeding the R56 cooling system. See if it is helpful as well.
Actually I believe there is a bleeder screw. According to ECS Tuning and Mini Mania the part number for the thermostat housing is 11537647305 for the N18.
See the image. The bleeder screw is plastic and on top of the housing (round top and has x on it)

+1 thats the thermostat housing ( 11537647751 newest part number updated part ) and the bleeder screw , its tucked down in on the top of the engine and sometimes hard to see right beside the engine wire harness. Also the sensor moved a bit.
Here is a shot of the N18 engine on the side with the older design N18 thermostat, the bleeder is in the same location just shorter now. Its in between the vacuum pump and the HPFP, if you have the newer N18 3/2012+ HPFP it will be the smaller looking HPFP.
Looks in between those location from the top of the engine near the valve cover, then use a flat head screw or phillips to twist it out to the bleed procedure., dont twist it all out or the screw with pop out and fall down in the engine bay, just twist it out to you see the bubbling of the coolant when you do the bleed procedure.
Actually, where there is a bleeder screw in the picture I have what looks like a sensor. There is a wire running into it off center, and a slot for a screwdriver opposite the wire. Still functions as a bleeder, and you can't lose the screw because it is attached by the wire.

Thanks for confirming the blended location.
Btw that's a great pic of the N18. Do u have one of the last version JCW N18 ? Great for looking at how things come apart and go together
