#4422 of 4441 Re: IBS problems [crayor] by Mr_Shiftright HOST Oct 20, 2009 (4:57 pm)
Replying to: crayor (Oct 20, 2009 3:57 pm) 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.

#4424 of 4441 325c noise by mnatale Oct 25, 2009 (11:06 am)
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?

Replying to: mnatale (Oct 25, 2009 11:06 am) 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. Replies to this message: mnatale (Oct 28, 2009 6:51 pm)
#4426 of 4441 Oil pressure problems, 1980 320i by ccasterline Oct 25, 2009 (5:43 pm)
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? Replies to this message: Mr_Shiftright (Oct 25, 2009 6:31 pm)

Replying to: ccasterline (Oct 25, 2009 5:43 pm) Must be a stuck oil pressure relief valve.

#4429 of 4441 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?

Replying to: rhmass (Nov 05, 2009 9:29 am) 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.

Replying to: srs_49 (Nov 05, 2009 9:44 am) 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.
