Problem for BMW 2001 5 Series
2001 530i battery drain/alternator question
I had my 2001 530i serviced at the Dinan dealership and
everythinglooked fine. Four days later the battery is dead. The lights
turn on,the radio turned on, but the engine would not roll over to
start, thedash simply flashed a yellow caution light at me.
Ihad the BMW dealership look at the battery and they simply gave me anew one, even though my battery was only 2.5 years old. Two days later,the same thing happened. Now they're telling me it's the alternator.
How did they miss problems with the alternator before?
Also, the AAA guys who jumped my car said there was a 4.1amp drain on my battery and that the problem was not my alternator.
I'm not sure who to believe, I feel that the BMW dealership is jerking me around.
Help.

- I read on here and the dealers also said similar models this age have had problems with the heating system, that perhaps is draining the battery?I've literally left the car for 10 minutes and returned to a dead car, would the battery really drain that fast? I also do very short trips around town, one mile spurts between houses, etc.
I guess I'm believing more and more it could really be the alternator though...hmm.

its easy to change parts and harder to diagnose the problem. sounds like you have an open circuit some where causing the drain it might be in the alternator

first off never never never trust a tow truck driver they are idiots, it takes a BMW 15 mins to go into a sleep mode before a draw can be mesured, as for the dealership they should have caught that using the Midtronics batt/alt tester that is standard from BMW 2.5 years for a batt replacement is reasonable especially in a BMW based on the high demand on the electrical system, I just replaced an alt on an M54 enginge just today so they do go bad, have them give you a print out from the midtronics with your VIN on the printout showing your alt is bad and what the batt is.

- the thing in the heating system is the final stage resistor and yes those can cause the batt to drain to tell if it is bad see if the fan for your HVAC stays on when it shouldnt, also if the fan speeds are eratic, if either one of these then yes get it replacedYes
