Our 94 E320 had a check engine light come on last Friday evening.
I called a local service shop and the dealer we bought it from and they both explained...if the coolant is full, oil is up to level and the car seems to run fine as it did before the light came on then it "should" be ok until you have a chance to stop in so we can read the codes.

Oue CEL is solid, no flashes. Any clues? I have an appointment tomorrwo morning at Overby's here in Jacksonville for them to read the codes. I'd like to have some information on hand before I go in tomorrow.
