Does anyone know what is going on or how to fix it? I have seen other posts about it but not a solid answer. Any help is appreciated.
How old is the battery? I know that you just bought the car so check the numbers on the battery. They will vary---some will be i.e. J 05 which will be OCT 05. If the battery is over 3 years old, you will be better off to change it. This car is voltage and amperage sensitive,as you will read. I would start there. Also check the tire pressure--sounds funny but the difference in pressure can trigger the light---REALLY. Also go to page 135 in the manual---Synchronizing ESP
