Hi fellas
Appreciate it if you can go through this error list and tell which ones are fatal and which ones are harmless. These are of a vehicle I took for a diagnostic test today (prospective buy) I posted about the same vehicle last week as well (http://www.mybmwi3.com/forum/viewtopic.php?f=3&t=5263)

As you can see from the pictures there were 49 outstanding errors and I suspect some of those are due to bad 12v battery. But the question is which ones are major errors and which ones are trivial ones. We cleared all fault memory and had a brief test drive (about 4 kms) to check whether any errors reappear after driving. Only the following three codes reappeared even after the test drive
8040BD Terminal 30F reset or deactivated
804398 Automatic air recirculation control (AUC) sensor: line disconnection or short cct,
804399 Automatic air recirculation control (AUC) sensor: Invalid PWM signal

I guess the two about AUC sensor are minor ones though I’m not sure about the one about Terminal 30F.
Appreciate it if anyone of you who are familiar with these codes can share information about those. I want to know the scale of what I m going to get into and gotta decide whether to steer clear from it or to make the plunge.
