Odd Electrical Issue
I had bought a new battery for my 2005 c6 this winter (2 months ago). The car was garaged so I did not use the battery at all. I charged the battery up all the way and drove the car around for a while. I came back home and let the car sit for 2 days. The battery was dead and I had to recharge it...interesting. I recharged the battery then dorve it, brought it back home and tried starting it an hour later.
When trying to start it again the car seems to have an odd electrical issue when attempting to start.
-clutch in and press start button.. no dash lights or start & seconds later with acc. off the gauges lit up and did a full guage sweep.
Any thoughts?

I dont think its the battery, but it may be.
I just went and checked the FOB is reading fine (originally though those batteries may be dead), but the car unlocks the column and then powers down when you try to start it.
Any other opinions on the forum?

Update:
The issue is not the battery. The car some how is draining the battery when the car is off. The alternator is doing its job when the car is running, there is just an issue when it sits.
There was an error code that flashed when driving the car (flashed on the dash): it said: Service Charging System...

Does this reflash mess with the ecu? I just had the car re tuned on the Dyno. Will it mess with the tune?

I did do a search on the dead battery syndrome and it appears that you were actually one of the people that were involved in trying to find a fix for this. When I am trying to read the posts on one of the DBS threads, an odd thing happens, the thread only shows a few of the pages. Im not sure if its a closed thread or not, but its not allowing me to fully understand how to fix the issue.
Was there ever a clear fix for DBS? I see that you can get a reflash, but some people said that did not fix the problem, correct?

i took a look at the first link and there seemed to be lots of speculation about reflashing the bcm. Most people said it needs a retune after flash, and one guy said it didnt. What are your thoughts?

If not, you can probably avoid DBS by slowing down your exit from the car.
Turn the car off in any gear, and wait a second. Shift to neutral a second.
And then shift to reverse and leave the car.
If you don't see the 'shift to reverse' DIC message you should be good to go!
I don't think any of this has anything to do with the iPod.

just a hunch, check your install connections at the terminals and the starter
also it does make a difference to leave the ipod connected, unconnect everything upon shutdown

I actually dont own an ipod, but the previous owner put in ipod connection into the aftermarket radio head unit...the only way to disconnect it is to remove the radio and disconnect it.

If you have the dealer update the ECU the car will have to be retuned to current specs. I'm still not a believer in ECU reflash curing anything. Mine is a early 05 and never had any problem.

I am not having the entire ECU reflashed, just the BCM. So that should not effect the tune, correct?
