Asked by PrasannaPMC Mar 29, 2013 at 05:14 PM about the 2004 BMW X5 4.8is

Question type: Maintenance & Repair

Hi Guys, Battery ran flat in my BMW x 5 4.8is after I left the key on about 4-5 hrs, some interior lights were on and
CD Player was on. is that usual? or is it look like my battery has come to end of life? I thought it has more power
than that.The I call RACV, a guy came and first tried with tiny battery pack, connected to jumper start, but didn't start
and some alarm went off and display went blank. then he disconnected the + terminal to reset the computer and
tried again, nothing happened. Then he suggested to use more powerful source he had and it seemed had enough
power ( he should have done it at the first place without disconnecting the power terminal), but computer asked for
code before it starts. I have no idea about what is that 4 digit code and does anybody know how to reset that code?
Also is that OK to charge the battery with external battery charger through the jumper start terminals without remove
the battery out of the car ( while the battery is fixed in the car?)

You can charge the battery through the jumper start terminals. They connect directly to the battery terminals. I don't know anything about the code. It might be written in your owners manual.

Thanks for the quick reply, I tried to charge but it wasn't possible. sound the alam for 30 sec and cut off the power in the charger. it doesn't even show the power level of the battery on the charger when it connected to the jumper start but it does in my Nissan. how can I contact BMW on this issue? Cheers Prasanna
