C200 W205 eco mode not working. Please help
So 2 days ago I took my c-class in for service and everything was working ok. A few ours after y picked up my car the eco mode icon wouldn’t even show on the dash. I started looking as to why this can happen. The usual problem is the battery or auxiliary battery. Had them both tested and they were in perfect condition.
Even tested it with another mb battery that was new and nothing. I took it to the dealer and they say that something is causing interference.
So I decided to do what every human being does. Search in google. Which only made it worse. I read that it might be a faulty fuse, and that in some cases if a fuse is wrong it can fry the computer and even burn the car down. Can anyone shed a light on this matter please?

So this means when you use the dynamic control scroll sport, sport+ and individual dont work?
Im guessing you are only talking about the start stop system?

If it stopped working after your car was serviced I would call them immediately and explain. I don't know what service you had done but it's entirely possible they did something that caused this. I do find that the Eco mode is fickle. It comes on whenever it feels like it, and other situations where you'd think it should it doesn't. I know the car is monitoring various engine parameters to determine when it's ok to shut the engine off in Eco mode so it's possible you may not be meeting the permissive requirements.
When you tested your batteries did you have MB do it or a third party like autozone, etc.? If MB didn't test it then I would let them do it. Either way, if you're sure it worked before you had service then call them and explain what happened so they can fix it.
