Greets,
Sunday, my wife called me to tell me that our '03 X5 had a dead battery. She said that she couldn't remember anything being left on, but that she did remember the radio not turning off with the key like it used to. She shut it off manually.
I charged the battery and made sure to tell her to ensure that the radio was turned off manually until I could diagnose further. The car went dead again yesterday. I checked for current drain with a clamp on DC ampmeter, but could see none. The battery was at 13.8 v when the car was running. I had the battery tested at Kragen and they could find no issues with it. It is 1.5 years old.
Last night, I left in on the charger overnight with a 2 amp charge rate, and took it off this morning at 6:30 when I left for work. My wife came out at 9:00 and it was dead again!!!
I have already replaced the final stage resistor about a year ago.
The only thing odd that I see is that sometimes the radio won't shut off, and some times it does. However, even if it is shut off manually, there is always a faint glow on the upper line of the radio display, and the clock still stays on in that line as well.
I will pull the radio fuses tonight, to see if that temporarily cures the issue, but I would appreciate any insight that you all might be able to give.
Regards,
Gary
