You will lose a few things like time and some other items held within the IDrive, all can be reset details in the manual, you may also have to do a dynamic drive reset all depends. I would suggest that instead of removing cables from terminals, that you wipe down and spray on ACF50. This will stop the corrosion and protect the terminals into the future!!!!!!

Reason I ask, the positive terminal has some funk on it. Is it possible to put power o the jump terminals to keep power in the system? I am having problems with the drive control system warning? Checked and refreshed power steering fluid, have not yet checked alternator/battery, which was replaced about 2 years ago I think. What is ACF50, and I suppose I should have clean surface to start? Thanks for the response Michael

You should be able to use a jump box while the positive terminal is loose. Use the jump connector under the hood, while cleaning the battery post. What drive error's are you getting on the IDrive?

Good Luck!

Herb the warnings I am getting are drive control system and start off assistance inactive which knocks out the dsc system. Sometimes goes for miles no problem then bang goes off

Your problem could be an electrical problem from either the battery or alternator. How old is the current battery? Have you had any starting problems with the car?

Battery was changed in 09, and I looked at it the other day and saw the positive terminal had some funk on it, so I cleaned it, but still showing code of the drive control system warning. Hoping that as I drive it more it might get the battery fully charged, but have not seen any kind of starting problems at all. Alternator was checked the other day and it seems to be putting out good voltage even with a load on it.

It will take a battery charger up to 12 hours to charge the battery if it's low. Driving the car, will never get it charged back to a full charge. If the car is hunting for a constant idle RPM, chances are that the alternator has problems. If your idle starts to fluctuate, put a volt meter on it then. If your voltage is exceeding 14.4 volts, your voltage regulator is bad.

Good Luck!

Herb, the idle seems to be consistent. I did get a code today that I recall in my 335 that had a sign of a car on a lift and the battery was going out. Ever seen that warning? Then noticed that I had to reset my clock after that.

The car on the lift symbol means a service inspection is needed. This should not reset the clock, so it sounds like you possibly have a battery problem?
