The "Check Engine" light came on on my 2004 E320. Everything sounds and runs fine and the book says it is likely emissions so perhaps a sensor or something minor. (yes I checked the gas filler cap and yes I have plenty of fuel in the tank, LOL)
Dealer wants $125.00 to plug it in & my private shop charges $90.00 to run the same program.
Odd, when I called the MB dealer the rep said bring it when it is convenient, don't put it off but if it runs fine not something to get excited over.
I went through the dash options and it says there are no malfunctions.
Don't feel like ignoring it although in my Toy T-100 I would

Anyone have this come up and what was your problem when it was checked?
