Hi all,

 

I'm curious if there is a way to add "Coasting", which I reckon is the equivalent of putting the gear into Neutral (in manual gearboxes) while driving, to other driving modes like "Normal", "Comfort", or even "Sport". Honestly I don't like it when I accelerate then I let off the pedal and then I feel the gearbox slowing the car down... ?

 

Thank you

Dunno; any manual VAG I've driven under 20 years old has an overrun shutoff as long as the engine is gauge hot and over 1_200 rpm. This uses even less fuel than coasting.

with DSG too.

as i have read, all cars since 2019 have coasting by default in all driving modes,

can't imagine how will be mountain driving with that configuration.

 

i'm happy with current(DSG6 2016) 'D' mode and quick move of DSG lever,

which can give different behavior without open Drive Mode sub menu:

D - slow braking

N - coasting

S - braking by engine

It’s actually very different than putting the car into neutral.

 

when a car is in neutral fuel is being used to keep the engine ticking over.

 

when you coast the injectors cut off/use hardly any fuel as the rotation of the wheels is used to keep the engine going.

 

when you’re in E mode and coasting I believe the clutches may still be slightly engaged just enough to put the engine into overrun mode and keep it running with no or hardly any fuel usage.

 

the difference between no fuel or a tiny bit of fuel usage is petrol will just turn injectors off, diesel will still use a tiny bit on overrun

I thought I read in my GTI manual that you shouldn’t move DSG into Neutral whilst in motion

don't think it can be harmful

DSG lever has limiter which doesn't allow move N->D when standstill without press brake pedal,

in other case it blocked move D<->N while motion too.

 

personally for me, limiter is annoying option, because i can't see where is lever, 'N' or 'D', on the dashboard

that symbol is covered by Start-Stop icon 😞

(fixed in ~4 months newer cars, but not for mine)

 

 

Interesting information, so some of you happily do D <-> N happily during the drive, some of you wouldn't.

 

The conclusion so far is, that "coasting" as is in Eco mode is not available in other modes and there is no "option" or "hack" to get it for the 2016-19 models..

 

If anyone has other information, please share. 

 

Thanks all!

I strongly suspect this isn't the case.

Coasting in neutral does burn tickover-amounts of fuel, but provides no engine-braking so is still more efficient overall than engine-braking with no fuel burned.

 

I'd also put money on the reason for advice to not coast by shifting the lever to neutral is one of keeping proper-control of the vehicle and not a valid mechanical one.

When coasting, the engine still burns some fuel to avoid stalling. Just have a look to the fuel consumption. You'll see that it's not 0. It's around 0.7-0.8l/h instead, just as at idle.

When not coasting, engine consumption IS 0, for proper engine braking.

I have a 2022 (2023MY) Superb DSG. Mine goes in to 'coasting' mode quite often in 'E' mode, and sometimes but rarely in 'D' mode, never use 'S' but probably not.

 

During coasting mode a symbol appears on the dash and the rev counter drops to normal tick over rpm regardless of vehicle speed. 

 

A quick dab on either the brakes or accelerator and it drops out of coasting mode, the rpm goes back to the relevant engine speed.

 

I think this is the coasting mode the OP refers to which is not like previous posts think of as coasting when the engine is in override, it does seem to totally disengage the gearbox from the engine except you don't move the gear lever as it does it automatically.

My 2022 L&K 280 estate doesn't ‘coast’ in any setting -  very little information in the handbook.

Apologies for the extremely poor quality of the photo which was taken driving within private company grounds after leaving work this evening.

 

You can see my Superb is in 'D' (or 'normal' drive mode), but also notice there is no gear position shown after the 'D' as the gear appears to be fully disengaged during coasting. A circled 'e' also appears at the top of the screen showing it is in 'eco', the revs drop to roughly 1000rpm, and the 'power' meter is showing 0kw (zero).

 

This is the coasting mode which I believe the OP is referring to.

 

My wife's 2017 Octavia also has this function but it only works with the drive mode in 'eco', where as on my Superb it works in eco or normal drive modes. No idea about Sport mode as I never use it.

This post shows how it appears on the dash for those with traditional dials as in the wife's Octavia

My 22 Kodiaq is exactly the same the eco symbol at top appears when in 2 cylinder mode, and the D with no gear number and revs at idle when you lift off the accelerator ( Coasting)

This occurs in normal D mode as opposed to my previous 2018 Kodiaq that only coasted in Eco mode.

What matters is that Coasting Function with DSG's works differently with the various TDI's 1.6 or 2.0, then TSI,s 1.4 or 1.5 ACT. then 2.0

Then there are 6 or 7 speed wet clutch DSG's or 7 speed Dry with a TSI with or without ACT.

My 2023MY Superb 2.0 TDI 150 DSG coasts in both 'eco' and 'normal' drive modes (not used 'S'), the wife's 2017 facelift Octavia 1,4 TSI DSG coasts in 'eco' mode only. 

@cncvery different engines and DSG's and generations even when Euro 6.

Your wifes is pre WLTP, pre GPF, & a DQ200.

Your MY2023 TDI can be different from an older 2.0 TDI or TSI.   Engineered to get the lowest C02 g/km during the test regime.

Looks like there could be a relationship with dsg generation and the modes as suggested by Prof. Root.

My guess is the dq200 and 250 coast in eco only. Then the newer boxes (380?, 381?) Can coast in D also. Maybe depending on software and conditions.

My dq250 Octavia certainly did it in eco only.

My 2016 SEAT 2.0 TDI SCR DSG (DQ250) had no Eco mode and you just ticked the box to enable 'Coasting function' and that was it enabled and it was available in D or S if you were toe off the accelerator and no power was needed.  D 6, D5. D4 or whatever just went to D.

 

There are all sorts across the VW Brands, vehicles, years, 1.0. 1.2, 14, 15, 1.8 TSI's,  1.4,1.6 TDI's with DSG's. then the bigger engines and different DSG's and engine managements. 

 

My picture from the post in the thread that was linked a few posts up.

MY21 280 DQ381. Coasts in E and D but not S.

Probably from the olden days of driving but I’ve always thought moving an auto lever while moving was criminal. Not sure these days.

 

I understand coasting is dipping the clutch - not in neutral but the same effect on the engine. I concluded its been decided the payoff of no engine braking & using idle fuel is better then engine braking and no fuel but slowing down quicker and having to add throttle sooner. Either that or it’s to try and recover reputation after dieselgate

@travs I read in my GTI DSG handbook that you shouldn't move the DSG into neutral on the move.....after I had done it a few times. 

Manuals and dipping the clutch to 'coast'  was a thing and the way that 'coasting' was know to be.

 

Different times, different era and Automatics or Automated Manuals, and the tech is designed in to meet modern Emissions and test regimes, 

even if they are done on rolling roads. 

 

With Mild Hybrids, PHEV's and now EV's 'Coasting' can be were regening of the battery is happening and with EV's there are no clutches to be disengaged.

 

The car can decide if no power / drive is required to maintain speed, or even if all the cylinders are required or the engine needs to be running.

Like a lot of car stuff if it works for you and you don't mind the feel then it's surely a good thing. Any way of reducing emissions etc.

For me I didn't like the way it did it on my Octavia. The near zero coasting felt odd. My GTE on the other hand does it (presumably as per the vid above) but with the near instant response to drive of the electric bits I do t feel out of control like it did with just a ln engine attached. Also it shuts the engine off so you get actual zero tailpipe stuff. 

 

All just preferences.

There are coasting settings in drive profiles so this can be edited with dataset of gateway.

DQ381. Coasts in E and D but not S.

same on my 2019 4x4 TDI
