E46 asthmatic air con

[ferg1986]

Hi chaps,

I have a 2002 318 with recently working air con.

I got a mobile ac chap to recharge the system as I thought it was just low but still no joy and he tells me there is an electrical issue causing the pump not to file.

Fault codes are ZKE central body electronics fault 7 and light switch centre 2 fault 5.

I’ve tried disconnecting and reconnecting the battery but with no love so far.

Is there any home brewed solution anyone has to this?

Many thanks

David
