This just happened and my immediate response was to run to this forum.

Was just driving along when warnings happened.

Details:
2003 x5 3 liter
I do not know the age of the battery.
It has been raining quite a bit around here (Tampa...Tropical Storm Isaac)

I looked up the warning message in the book: Paraphrase: Electrical engine fault, see dealership.

Thoughts? It seems to still be driveable but very sluggish acceleration. HELP! Thanks in advance.
