I sure hope so. I can see the same frustration from every post I read with the same issue, so I'm feeling everyone's pain.
Just thinking out loud again...now that I think about it, I saw the BAS/ESP light come on twice in the midst of of me disconnecting the battery multiple times. I remembered reading how to reset it, so I didn't think anything of it.
Also, back in April when I had my Eurocharged tune done, I had to hook up a battery charger to complete the process.
So, I know my battery isn't at 100% condition. I can't imagine that would cause a problem, but who knows?
