On my E30 318i it was the heater matrix.

Basically strip all dah trim and it slides out into the footwell. Mines is a right hand drive, being here in the UK, and the matrix was about £100. I did have a leaking heater solenoid too. Fixed that and shortly afterwards the matrix leaked.

Easy way to tell, assuming you have coloured coolant (ours is tinted red) is to drop towels or something onto the carpet.

Common leaks are from a clogged rubber "elephant trunk" spout that comes from passenger side plenum (beneath the windshield), or one of 4 clogged sunroof drains (1 in each corner of open sunrooof). I had a weird leak coming through a hole in the bottom of the plenum which i sealed with silicone all along the bottom of the plenum, which stopped water from dripping through the firewall and in behind the glove box. Hope that helps. Plenum is accessed by prying the black plastic grille on passenger side below windshield wiper.
