I have an Indy that has worked on my wife's 3...I think I will take it to him to scan. I do not believe the dealer scanned for error codes.

I was having a battery drain issue prior to replacing the xenons. It has been ongoing for over a year. There have been random times that the car will not start due to a dead battery. It always happens at home, always in the morning, and the only other common denominator is that I do not lock/alarm the car when it is in the garage. I have replaced the FSR. The wacky electrical symptoms have only started recently. I replaced the xenons after one bulb went purple and then died. The OBC told me check low beam. I replaced the bulbs at that time.

Yesterday, the car would not start. When I jumped it I noticed the following:
-Headlights took a couple of seconds to come on after the start (but they did dip)
-ACC was in Celsius
-Fuel gauge was not working
-RPM gauge was not working
-OBC display was dead

Had to jump start again this morning, but all symptoms above were gone. I will try disconnecting the battery for 1/2 hour tonight. I just know that I have a short somewhere. I was thinking LCM as well, but I want to narrow it down. Thanks for all the advice.
