My S 430 must have like the flu or something. If it's not one thing , it's another. I went out to start my car and couldn't get any power. Luckily the NAVI system said "Battery Voltage too low". So I called AAA and they came to jump the car. The guy said that if I left the car idling for 45 minutes, that the batter would charge.
I followed those directions, and the car worked fine....that is for the next two days. This morning, I go out to the car and...tada...dead, no juice....locks would barely pop up on the doors, and the lights would barely flash on my rear view mirrors.
I am pretty sure that I need a new battery, however, I don't have that much faith in my service advisors at the dealership. They told me that they need to test the car again because something may be draining the battery in the electrical system, however, I had the car in to check the BAS, ESP and Airmatic about two weeks ago, and they didn't mention anything about the battery. If I can change the battery to solve the problem, I don't want to spend 105 per hour just for them to check the same stuff that they checked 2 weeks ago...only to tell me to change the battery.
