I just bought a 2008 Mercedes E350 with 92,000 miles. After 2 days of driving a message displays " Service c due in 14 days" .I called local Benz dealer and they said the oil will need changing. The place I bought the car from assured me they had changed the oil prior to putting it up for sale. How do you reset this message on the car. I have looked through the owner manual and not found anything about this.
It’s for an '07 model, but should be the same.
In truth, the place you bought it from, that performed the service, should have reset it at that time. Keep an eye on your fluids. I’m very untrusting of used vehicles - meaning I always treat them as ignored and do full fluid updates myself.
