If I disconnect the battery and touch the positive and negative terminals together? Someone told me that this will clear the system fault codes.

My Ride: 530I Silver gray with gray leather with Premium Package, Logic 7 Premium sound system with Ipod interface, xenon adaptive headlights, Active steering, Power retractable rear sunshade, Comfort seats, Cold weather package and M5 OEM 166 wheels, Sprintbooster. Ceramic Tint all around, Bilstein Sports shocks with Eibach springs, Brake performance Rotors and Axxis ceramic pads.
I'm not sure if that is a good thing to do. Some of the models have auxillary battery to store the memory. I just found out about this so called battery and it is mounted on the rear drivers side fender well in the trunk. It actually looks like an amp rather than a regular battery.

The procedure you mention (and leaving them hooked together) is a known fix in the E38's to clear memory and re-set several systems, but it does not clear fault codes. With the more sophisticated electronics on the E60, I am not sure I would try it, nor have I read where anyone has recommended the procedure.

Are you suggesting disconnecting the car from the battery terminals, and connecting the positive and negative terminals of the battery with a single wire? Because thats generally a bad idea even with a small battery let alone a car battery.

he means touch the battery cables together, not short the battery terminals!
but I agree with the others, worked on older BMWs, but between the IBS on the negative cable and the pyrotechnics on the positive cable I wouldn't do it on the E60
