Not to worry its all sorted now, just needed coding.


Thanks

 

BLooD I wondered if you could help.

I have my friend (Ex BMW Engineer) performing my AC High controller retrofit. My car is E60 2004, the car it came off of was LCI 2007 model. He has told me he has done the pin swap on pin21 but he is still getting a constant running fan and no/little AC.

Any ideas?

 

OK, did the switch from Basic pre LCI to LCI advanced and now the AC is not working correctly. I only did switched the unit according to this DIY, no coding done yet.

The AC is blowing only hot air while the car fan is not reacting at all.

Anny suggestions?

 

coding, if not come back and post, date needs to be an lci one before coding

 

pin 21 goes to +12v, the other end of that goes to ground. Once that's done then code it and it should work

if not might be a software level issue

 

anyone sorted out the AUC sensor prob when retrofitting LCI climate controller panel

 

Hi Phillc, just done the same upgrade and having the same problem with the ac not working. Could I ask what coding you done to fix the issue??
