I just fear driving it or even running it without figuring the problem out because although Im certain everything is fine now, car runs fine, they said it drove fine, actually had CEL on pre new rad, now CEL is off. Oil on dipstick is clean too. I do have the ABS/traction control/random. other light on as well, which seem to either come on out of no where and stay on, or come on when car is started. don't know if that has to do with anything or not.

Also, no goo under cap as of my arrival back to Miami.

Ran BMW scanner 1.4 before I did the drive back down, saw AUC sensor, another code related to short circuit, possibly IKE as well in another. Any relation?

I know is seems like I'm over looking this, but I basically just had the engine rebuilt as of last summer, so nothing will be overlooked.

I know it sounds farfetched, but could fuses have any possibly play? maybe electrical connectors for heater control valves/related parts? Don't know if coolant spraying around could possibly cause a bas connection somewhere.
Also, climate control fan (I believe) weather l put it on cold or hot, would make that horrible squeal/whining noise that would go away if I put on full blast. Heat was sub-optimal at best, a/c kinda sucked too.Heat would come and go. Noticed that when I got back down here tho, the month long whining noise suddenly disappeared....

Thanks again. JCL - planning on getting to a second opinion tomorrow, just need to find a place first. Finding a mechanic you trust is one thing, but when you have to balance the fact the 80% or so chance that the guy won't speak english, sort of makes things a bit tougher.
