My Ride: BMW 525dA 2007 pre-LCI.
Model Year: 2007
I have managed to make the compressor to work at the moment. There are some differences from the pre LCI wiring. (pin 5 and 8 from x18793)
There is 1 wire red yellow (bigger than the others 0,75 i guess) that i don't know where to put. It's pin 2 from X18793. Some advice please.
L.E.
I did some diagnosis on the car and seems like I have the following 9 errors. Solar and condensation sensor will be installed later.
One question:
rear compartiment flap motor and stratification flap rear compartiment is the same thing? I have 2 errors related to this. The other DTC are normal to be present. And still where should I plug the red yellow wire previously at pin 2?

This is the dial at the back between the vents where the rear passengers can regulate the tempurature.
I don't see that in your list, so presume this is the stratification flap.

To find out what the missing wire does I will do this tomorrow ...
I will put everything back to original, code everything stock erase all errors.
Remove the red yellow wire from pin 2 and read DTC again because it should throw an error. This should give me a clue about it's function ...
L.E. ok tested and with stock setup and pin 2 red - yellow removed I have the following error and AC not working:
9C69 - monitor supply compressor clutch basis / no communication / permanent
What do you thing guys?

I have the same problem with AC not working.
Its because the controlvalve for the clutch and ac compressor is wired differently on Pre LCI and IHKA BASIC vs IHKA HIGH.
2 pin wiring for the basic and 3 pin for high.

I have mine working at the moment just as I explained before. Pin 2 is not connected anywhere at the moment. I have solar sensor installed, but LCI cars don't have solar sensor from factory. Any news here?

I am 100% sure. A friend of mine has an e60 my2009 with high AC from factory and no solar sensor installed. Another thing is I installed in my e60 lci an lci pannel. Look at the errors I got. No solar sensor DTC before or after installation. Without the sensor i even got some values on the diagnostic tool for the solar power in Watts so the IHKA panel must approximate or something

Solar sensor you need to make aktiv with coding, and if I am not mistaken it is default nicht_aktiv.
Same for the condensation sensor, for which you have no error either.
Don't believe either there is a high version without solar sensor since it is not in the option list.

Both solar sensor and condensation sensor are set to Aktive as default when you recode everything and I have the same settings now. THe condensation sensor gives an error because it is not installed. Beschlag sensor or something similar.
The LCI car of my friend with High AC does not have solar sensor for sure. I removed the IHKA panel and there are no wires for solar sensor installed.
