I have 4 coolant swithes on top of my thermostat housing, one I know is for temp gauge, anyone know what the other two are, one has two spade clip wires on it and is 0 ohms, the other two have locking connectors on them,

anyone know what they are??? my book does not show them and yeah it isnt a Bentley manual.

I cant believe someone doesnt know what the sensors are, I know this car I just got acts like it has no choke and wont increase idle when cold, I have to play with throttle to warm it up,


well I will keep plugging the net for info.

what year is it?

I have a 83' 533i, and a 85' 528e,

the 33 is what I was wondering about,
