Battery Disconnect

Jan 03, 2007 4 Replies

I need to disconnect the battery in my 2000 323i E46 to install a cd changer/ipod adapter. Anyone know of any cautions to take before disconnecting?



Does disconnect cause a need for reprogramming anything on the vehicle (radio code, on-board computer, .... ???)



I have diconnected the battery on my 2000 323 with no problems. You might need the radio security code to get it back to life.

I didn't on my 03 E46 M3, but I have nav

No worries, just disconnect it and everything will be back to life without a code.

Steve, any number of supply stores sell a very simple "memory" holding devices based on a lighter plugin male plug with a 9volt battery connector at the end of its wire. Putting the ordinary little battery into the connector and then plugging it into the socket seems to work fine and safely.
