DSG Eco mode on restart

[ffvrs]

I’ve noticed on my Superb that when in ECO mode when I restart the car the gearbox defaults to the standard ‘D’ mode. To get the box back into ECO I need to re-select that mode.

 

Is this a characteristic and anyone know why ECO on the DSG doesn’t stick on restarts?

There are threads on this subject with no definitive answer.  Mine will stay in ECO after a restart, but others will say they have the same problem as you.

Later models revert to standard mode after a restart. Earlier models will remember your settings. 

I don't know what year the changeover happened.

My 18reg facelift SEL Octavia (OP mentions a Superb, presumably the same software?) reverts to D, but the ‘mode’ display still shows Eco.  I now know to press the mode button 5 times just after starting, to regain Eco. (I like the ‘coasting’ feature)

Yep same here

I like the coasting feature too… funny as back in the day motoring specialists said coasting in a car uses more fuel, and it’s best to leave it in gear.

My 2016 Octavia stays in ECO or D mode as I select using the Individual Mode option.

It would on an Octavia 1 diesel, because there was an overrun cutoff that worked when the car was in gear and revving over about 1_200, but when it was in neutral it was injecting idle fuel.

Or any vehicle manufactured in the last 30 years.

 

Whilst the statement may be technically correct at the moment of coasting the fuel saving is made through the vehicle gaining speed and momentum with the engine braking removed and how much further the vehicle will coast without engine assistance along the flat or up the oncoming hill.

 

Its a balancing act, to save fuel a hill has to be steep enough, the driver willing to perhaps exceed the speed limit and crucially the terrain beyond the hill, for example coasting down a very steep hill with a Stop junction at the bottom will not only use more fuel but needlessly work the brakes, coasting down the steeper motorway gradients definitely saves fuel.

Bear in mind ECO mode may do more than just enable coasting, depending on your engine.

Coasting means the engine is idling using fuel. With it in gear and going down a hill you're getting the benefits of engine braking and not using any fuel.

yep thats the what they used to say but as some else mentioned, on these modern cars you can't quite tell what other trickery they are achieving under the bonnet.

Nothing that magic.  Drive disengages and the RPM drops and the fuel is sipped if required to run the engine, and all this system helps the WLTP & RDE2 results and can save you fuel on the right roads if your toe is off the accelerator.

 

But not all DSG or engines are the same or modes and then there are the 3 or 4 cylinder engines and the 4,s with ACT / COD in addition.

thanks for the info.

 

i guess its one of those topics where you think at the end of the day, its not worth wasting any more brain power on and just enjoy the drive, which I can say i do very much.
