Consumer Battery Drain?
Hello All!
I have a 2007 SL550. I have been having some electrical issues associated with the Auxiliary battery. I am constantly getting the "convenience functions unavailable" message. I have replaced the battery twice and it doesn't seem to change anything. Every time I start the car it is having the issue, after driving for about 20 minutes it is back, then immediately upon turning off the car it is dead again and repeat. Only thing I can think of is that it has an after market stereo system that might be drawing too much?
Any thoughts on troubleshooting tactics? Thanks so much!
