V1 and battery

[SilverBullet]

Quick question for you guys. Last week I went out to start the X to get to the airport. I turned the key, and the car started clicking and lights flashing, including V1. The car would not turn over. I stop and tried again a few minutes later, but there was less power, and eventually the car went dead. I called BMW roadside for a jump. After the jump I tried to see if a dealer or independent could replace my battery, but no luck. I was already late for a flight, so I just went to the airport. I figured that I would need a jump again, as I went away for two weeks. When I came back from my trip, I went to the X, it opened with the remote no problem. I then tried to start it, hoping that it would work, and it started up, no problem. I went to the dealer yesterday to have them check the battery. They said that it was using more power than normal. 60 volts. They said that it is probably the V1 hardwire. I am a bit skeptical because I have had the V1 hardwired for almost a year now, and this is the first time I had this problem. I was wondering if anyone had any problems like this? Any suggestions? Thanks.
