I thought that was normal? Eco mode changes the fan speeds etc to save fuel.

I'm sure there was something mentioned about this in one of the Duster forums......something about "smart charging" but I can't seem to find it now.

Ok, after an exciting drive fiddling with the volt meter I can confirm my 2016 Logan (DCi90) has regen. braking and a Smarternator.
 Mine is the same volts but the fan speeds drops with engine on tickover/low revs
Key in ignition, no start: 12.2 volts
Start engine: volts creep up to 14.8 vdc, obviously under ECU control, then drops to 13.5.
Drive: volts immediately down to 12.8.
Come to downhill bit: foot off accelerator: 14.8 volts every time, then immediately back to 12.8 on application of accelerator.
 
Rinse and repeat: regen.braking happens every time you lift off the go pedal. It doesn't happen when you brake. Air-con and fan on makes no difference.
 
However, with headlights on the volts are at a constant 14.5 vdc.
 
I couldn't hear any fan pitch change during all this electro-malarky.
