Well all that means is that a shorted battery would discharge a LOT of electricity all at once....like say shorting out a toaster. A shorted battery cable would smoke and spark. Remember, a car battery has a great deal of power in it, to turn over a 200 HP engine---make it spin, in fact!
 
So the idea that this battery discharges from a "short" and does no damage to fuses, or any other components, or any wires, but selects just one small device to fry---well it makes no sense, if you see what I mean.
 
I'm not saying the battery sensor wasn't bad, only that I really doubt that a few raindrops sprinkled on the top of a battery is going to do that.

325c noise by mnatale

When I start up my 2003nbmw 325c it sounds like a pump bering or belt is squealing it stops a little if we are driving and is noticable again when accelerating from a slow idle. is it most likely the water pump going? if so, how long until it goes or is it possible to be just the belts need replaced?

Probably a belt or idler pulley. A water pump that is screaming for mercy is not likely to stop and start again with making noise. And usually, a bad water pump is a growlling noise, not a squeal.

Oil pressure problems, 1980 320i by ccasterline

I just acquired a 1980 BMW 320i that is blowing the oil filter off after running for a few minutes. I have pulled the spark plugs and cranked the engine for a while, but the oil pressure didn't come up. What should I do next?

Must be a stuck oil pressure relief valve.

Key pod problem by rhmass
Nov 05, 2009 (9:29 am)

I noticed recently one of the key pods used for my 2006 3 series occassionally wouldn't work in locking or opening the car door. Although it always worked after numerous trying. Is this a battery issue, since the car is over 4 years old? I hope it is not a key pad malfunction as I know it is quite expensive to replace one.
 
Anyone has the experience of replacing the battery in the keypad? TIA

I would replace the battery first. It should be fairly straightforward. On most of the ones I've seen, the top and bottom halves just snap together. Just twist a knife blade along the seam and the two halves should pop apart. Look carefully though to make sure there's not a small screw someplace holding the top and bottom together.

Thanks for the advice and suggestion. Are these batteries available at BMW dealers only or it is the generic kind one can find in electronic stores such as Best Buy? I do see the two snap points, so it seems pretty straightforward to open it.
