Hello, my name is Megan and I'm new to the site and wanted to introduce myself first of all and second ask for some advise/ help with my 03' E55 AMG. I recently bought the car used from a friend of a friend and it has a few issues that I am concerned about. My number one concern is a service light that keeps coming on that says " NO OIL SHUT OFF ENGINE" or something like that. I contacted the guy I bought it from and he assured me it was only because it was in need of an oil change and the light would go away once I did that, well it was gone for one day and is back. Also a service light is on that shows a picture of a battery that says "visit work shop". Im affraid to drive the car now. Can anyone help a poor girl out? Any advice would be greatly appreciated! Thanks, Megan
