2001 e320 dead

[dwc57]

Any help would be greatly appreciated.
It is a 2001 e320 wagon. I love the car, it has been nothing but great. I have done all of the service as the dealer has recomended up till now with 72000 miles. So here is what happened.
Last week the air bag malfunction came on. Tonight abs, and bas malfunction lights came on. The car would not shift into lower gears which I read is called limp mode? Now the car is in my driveway and will not start. It seems to have power but will not turn over.
Can anyone help me.
Thank you..
