Just an update.Found out that the air con gas is fine and the issue is related to my previous thread (http://www.bmwfanatics.co.za/showthread.php?tid=38763) Apparently the head unit controls part of the cooling system so my search begins for a new head unit :argh: Big thank you to Yusuf (M3M5power) for the assistance raise:
Btw if anyone knows where I can find a professional head unit at a decent price,I'd really appreciate it..
