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

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.

BANG!

Exactly!

When we get bored in physics labs we vaporize copper wires by laying them across car batteries. Literally it turns the copper from solid into a gas.

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

i wouldnt do it. you are essentially shorting any capacitors that may be storing power.
