I was out for a longer run today and can confirm that you can ‘coast’ in Comfort and Adaptive drive modes.

Hi,
Will try the rapid double upshift next time I'm on highway. I enabled coasting in comfort by coding. Here's what I coded, using E-Sys & ProLauncher, but should work with Bimmercode in Expert Mode: * DKOMBI4 ECU Anzeige_Configuration> 10Seglen_In_Comfort_Modus from 00 to 01 * HG_MGU: Not sure which function --UPDATED 3008 FES>Global_Conf_Sailing from 00 to 01 3008 FES>Eff_Dyn_Sailing from 00 to 01 3009 Efficient _Dynamics>Sailing_Counter from 00 to 01 You end up with a check box to check on iDrive under SETTINGS, CAR This will give you coasting in Comfort; you should already have in EcoPro (check box in SETTINGS, CAR,DRIVE MODE) Hope that helps!

When you say you’re not sure which function, are you saying you’re not sure which of those three actually enables coasting? Thanks in advance |

All this sturm und drang for a sip of gas.
Why didn't you just buy all-electric to begin with?

this does not happen with me. The engine literally shuts off if I'm coasting (like start/stop but in motion). I think this happens in both Comfort and Eco Pro, but don't quote me on that.

X32G20 ,
Sorry for the confusion. No, not all; at the time when I made the original post, I couldn't remember what section of the Head Unit, those items were in & I mistakenly called "section" "function". The section is useful when searching with Bimmercode See my original post, which I updated Hope that helps!

For a change, I want to turn off coasting, as I understand correctly, I only have to do these 4 things, only the opposite...

No, an ICE engine without fuel cannot "keep running".

Do you mean that the forward motion of the vehicle is enough to keep the engine turning, with the transmission engaged, even though the engine is not running because fuel is cut off? |

Yes, it is as simple as that. Typically the engine will start fuelling again just a few revs above idle, to ensure smooth transition back to running state. My first petrol motor with fuel cut off on the over-run, was a 1990 vehicle.

Spot on. Some engines also have a system where if running light loads some of the cylinders will shut off. I think one of my Jaguar V8s and a Holden with the 5.7 litre V8 both shut down one bank of 4 cylinders when just gently cruising, i.e. they weren't being fuelled until you called for more power. The Jaguar in particular (a 2003 XJ8 X350 series with the 4.2 litre motor) was remarkably economical for such a large car.

Question here:
Then, what about staying on Drive mode at the traffic light? Do you think it will save more gas than being in Neutral position? |

I love "coasting" and passing people never touching the throttle. I will never understand why people brake going down a hill when there is one you are about to go back up just in front of it. Just let it ride buddy.

Has anyone tried this on a 2019 330i? My car definately coasts in Eco Pro mode, and I coded the 4 settings above to enable it in Comfort mode (and ensured the new checkbox is checked) but I haven't been able to get it to coast in comfort mode.
Does it matter if you rapid double upshift via the paddles or the stick shifter? I'm just noticing the image from the Eco Pro screen showing the tip with the stick shifter and I'm wondering if thats what I have to use instead of the paddles which is what I've been trying with (using the stick shifter while in regular drive mode doesnt make sense to me when using the "upshift" term since its not in manual mode). |

I wouldn't have thought it would make the slightest bit of difference. If you want to save fuel, use the Auto Stop/Start. I know some on here hate it, but I use mine all the time, just overriding it by flicking the lever across to Sport if I ever feel the need (e.g. making a turn across traffic)

Auto Start/Stop is the way to save fuel indeed. I use it mainly when I have to do a quick stop in order to not turn off completely the engine (like a quick stop under 5 minutes). In Traffic, I’d say, it would depend of traffic in your aera. Got surprised a few times on ECO while I had to start quickly to avoid car coming and throttle was squishy with no response lol. So for me Eco is definitely more a highway mode than a city one as the throttle respond very slowly. BTW I like your technic of switching modes on purpose for scenario like I’ve just described. |

Older auto transmission definitely saved fuel by being in neutral. Most modern ones fully disengage when you are stopped and it's still in drive mode. I can't guarantee it but I would be absolutely shocked if it made an difference in the G20 with ZF transmission.
