Anyone able to help me diagnose these codes my 530e is throwing? No check engine lights but decided to see if it would throw anything and I got all the following back:

Unless the car posts a CEL or engine light I wouldn't worry too much about these shadow codes. My car has all sorts of weird codes when I scan it. You'll go nuts chasing all these down. I would clear the codes, drive for a few days and see what come back. Then focus on what each one means.

The fact so many sound similar would make me believe one of your control modules had a brain fart one day. Probably nothing to be concerned.

Since most of the fault codes appear to be associated with the IHKA (your ac/heater control panel)...have you done anything recently to the sytem...like coding some different parameter?

As already mentioned...the IHKA is not associated with the car's emissions system, so you won't get an Check Eng (OBD II) warning...and the IHKA isn't a system that the car's check control system would give a warning for either.

Never coded anything but I cleared all the codes a week or so ago and they stayed away the remainder of my drive; just checked again and the same ones are all back...

Hi,
I know this is old Thread but I am experiencing the same issue (exactly same fault codes).
Did you ever manage to get it resolved?
