Interior Antifreeze leak

[greenlightracer]

My 325i leaked a little bit of coolent on only the driver's side of the passenger compartment. My dad said it could be the heater core, but I just used the heat last night (after the leak) it leaked enough for my coolent light to come on. What does this mean?

It's most likely a bad heater core. Eventhough it leaks it will still put off heat when the heater is used.

are they expensive in these cars?

isn't everything expensive on these cars? :P

i have to say, it does feel good to save almost $150 just for five minutes of soldering -

$15.00=soldering iron+2 bulbs from Radio Shack=working backlight on OBC

End result:
ME, THE DRIVER HAPPILY BASKING IN CLASSIC BIMMER-ORANGE GLOW EVERY NIGHT on my way home from work, and I know exactly how much gas I have left now too!!

Conversely:

BMW dealer=2 days without car+$150=same end result (minus the satisfaction of having done it myself)(minus food for a week, due to the $150 on the other side of this equation)=DEALERS SUCK ASS

I never really was any good at math, but I think I did alright this time. LOL

Could be a cracked control unit. It is part of the pipe with the electronic valve. This is made of plastic usually and could be cracked. it si located between the firewall and the heatercore on the driver's side. has a two wire plug that goes into the top or it.

Pick one up at a salvage yard, but make sure it works, the thing is a pain to get out if that is where it is leaking.

could be it, cause I just can't figure out where the leak is coming from.... I couldnt do something ike this myself tho....
