Hello friends. I have some problems with my E60 530D 218hp 2004year. So first, I make mistake trying to change VIN number of my CCC navigation with OEM ICOM Next A only and WinKFP software, I just forgot about ICOM B for MOST, now my CCC is stuck on BMW logo. After I make this mistake, I try to change VIN of my KLIMA(IHKA) module and everything gone well and was OK. But later in the same day, the AC stop working, the green LAMP is ON but not cooling. The another problem after that is the big engine cooling fan, working all the time, I am not sure this problems are based on VIN change of KLIMA but... I am scared and I don't know what to do. Please help.
