Having problems with your 1989 Peugeot 405 ?
I want to change my battery,on my peugeot 307 2ltr diesel but can this be done without loosing the codes
There is an item called a "setting saver" or something like that. It's a small power supply that plugs into the cigarette lighter, that keeps radio and computer active while changing battery. (I imagine you could make one by attaching a cigarette lighter power adapter to a good battery and plugging it in there.Don't use one with a transformer, just straight 12v!
