how to set the starting dynamic (agility) setting to ECO
The big question is if it is really saving fuel, or in other words, is it worth the bother?
My next question is what ECO will do different from Comfort mode? I read it will reduce the air con, and heated seat. What else will it do to save the fuel? Is it really saving fuel and how much? Is it worth to worry about if it is sub-10%?

The heated seat is an electrical function and is not effected by different mode settings. But yes, the A/C is dialed back. As well as throttle response, ignition timing, mapping, boost(not sure on this, just guessing), as well as a few other things that simply dial down power of the motor to save fuel.
You'll likely only gain 1 or 2 MPGs when in "ECO" mode compared to "Comfort". Only way to find out is to calculate your mileage by driving a few tanks of gas in each mode. It's hard to be scientific about this since there are so many variables while driving, but if you do very similar driving throughout each tank, it'll be close enough.
At the end of the day, if you're driving a Mercedes, you really shouldn't be concerned with a difference of MPGs. That's for people that can only afford 7 year old Kia's. Just my opinion of course.

I have a vendor that MIGHT be able to program this via obdii as they currently make a module that reprograms eco mode off permanently.
They are out of Russia and asked for the controller!
If this works, it will be better than the mid city module and require no wiring...
Vediamo is one of the tools that allows you to do coding and get all kinds of data from the many ECUs on the car. You can get hold of Vediamo easily enough but the engine control modules on the 205 are locked down to protect them from changes. Some people out there claim to have cracked the seed/key/response algorithm to unlock modules but its all murky business. MHH Auto forums is the place to look if you want to explore that world in more detail.

Dapper - when u think of the liability potential from permitting people to fiddle with car software, I'm not surprised!
What surprised me most was the responsiveness of Eco, at least in my car. It moves off the line IMMEDIATELY, much better than in Comfort. That first car length or two is all I care about. Of course, there is less total power, but the turbo and/or the engine does not have to wind up to deliver it. If I need more power, all I have to do is step on the pedal harder. Who floors it in winding lanes and 40-MPH suburban road? The overall effect is like driving a fairly powerful manual transmission car in a cruising gear and then stomping the gas without downshifting. It suits my driving style.

Could it be possible this isn't listed now and have to manually code the setting like the momentary blinker flash? If so what bits need changed?

Anyone know where in Vediamo to change the comfort transmission feature to last mode or which bit to change in MED40 via Vediamo like DBOC did on another ECU?
I did already configure the Eco start to last mode so it remains off now.
