I have a major gripe with the "eco inside a circle" icon and coasting when you have DSG.

I have a 2020 year VW T-Cross R-line 115ps DSG. One of it's features is coasting, where it disconnects the engine and gearbox whilst driving. All this I understand as I have this also on my 2015 Tiguan DSG. However the Tiguan is straightforward, lift off the accelerator, The car disengages drive and start coasting. Gear display switches from D+number to D showing the car is effectively out of gear.

However with the T-Cross I've failed to determine the conditions when this happens. I can see it happen, gear selection looses the gear number, just showing D, and eco in a circle appears on the dashboard. However, it appears inconsistent, I can be driving along, lift off the accelerator and it starts coasting, I reapply drive and it reengages gear. Moments later I lift off again and it doesn't coast! I can keep to a set driving style, maintaining the same speed, and the car will and will not coast seemingly randomly.

It's not specific to a speed, a range of gears, or any other condition that I have been able to determine. It's driving me mad as I cannot determine with any predictability when or where the car will enter coasting.

The manual is no help either as it simply says coasting exists, within a speed range not even mentioning the eco light. Where it does mention the eco light it doesn't mention coasting, simply the car is in eco mode! The manual also suggests you can switch the mode on and off, but in mine certainly you can't.

Anybody else being driven mad by this?

I found the icon coming on in the info display a distraction at first, but have got accustom to ignoring it now.
Don't really see the point to be honest,

Yes, Tricky2, I've noticed exactly the same. Glad you brought it up, here's hoping for definitive answer.

I've never seen mine to show just D and this generally sounds confusing. Could be something VW tried in past models and got rid of in the newer ones. I highly doubt that the gearbox will disengage the drivetrain when you just coast as this will be both inefficient and dangerous. It's just that those small engines provide almost no engine braking (could also be intentional, I don't know), so you can can generally coast for longer than with older cars. If you need an engine brake on a long descent, switch to S or even manual to keep it in lower gear.

And about the "Eco" blip, I think it just flashes when you complete a whole "circle" (which is something like a minute) while diving within a certain "eco" specifications (light acceleration and braking and more coasting). I don't think it's directly related to coasting or engine/gearbox state.

Nope to all above, mine's a 2020 model year. Coasting is more efficient, as the engine revs are lowered to idle. Braking and control, drive re-engages instantly you touch accelerator, brake or if paddle shift either paddle.

"If you need an engine brake on a long descent, switch to S or even manual to keep it in lower gear." absolutely, but coasting's the reverse you want no engine holding the car back.

If you've DSG keep an eye out for it when you lift off the accelerator completely. As I say it's not consistent, hence my query, but it does happen. Check in the manual, though it's very little information.

Mine is the same as yours - R-Line DSG 115, but it's 2019 model. 11k miles on it now, never felt it disengaging the drivetrain while coasting and I am sure I can't miss this. It's always in gear unless I manually select N. It likes to stay at very low revs though (as low as 1500 rpm), so usually any slight press on the throttle will kickdown immediately, usually from 7th to 4th.

Do you tend to drive the box in sport? In Drive ours is quite reluctant to kick down. The engage disengage, you don't feel a thing the box does it so smoothly. It only happens in drive, nit sport.

It's as if we are talking about different cars. I drive almost only in D. Sport is a bit too twitchy for everyday driving for me. But in D, the gearbox is trying its best to stay between 1500 and 2000 rpm, which leads to frequent kickdowns on even the mildest acceleration.

Maybe it's the driver not the car :) must admit I do tend to drive for economy so tend to be quite light on the pedal. I also tend to use the paddle to drop down if needed rather than increasing the accelerator. These boxes do learn the drivers styles so effectively your car could be different to mine.

If you didn't know about it you probably wouldn't notice. The signs are quite discrete. Just keep an eye out for when running with the foot off the accelerator the gear switching to D with no number.

Hi from Brussels, Belgium.

I got my new t-cross recently. It 's a 2020 TSI 115 DSG. It 'a "Style" Line (SEL alike here in Belgium). 1.250 km so far. Excellent ride. I also noticed that the gearbox sometimes disengage. The active info display shows "D" (not "D + number") and the french words "roue libre" appear on the display.

I tried to figure it out how to activate this "roue libre" mode but in vain. It comes in Drive mode and in Sport mode, and on different speeds.

I also would like to understand how it works. Thanks.

Bye.

My dsg definitely doesn't do "coasting"...! Ran down a couple of half mile hills with foot off accelerator and car stayed in D7...
If you read my original post you'll see my big bugbear is it's not predictable. Your test may have shown it up on the First run, or not at all, or the next run you could have made may have showed it up. It may not happen at all or it might happen frequently, and that's what's driving me mad.

Oh, and it's not just hills, as happy to do it on the flat, when it wants to.

I see I'm going to have to try capture it on video as no one seems to believe me :)

It definitely happens. A couple of days ago I was on the level and noticed it when I took my foot off the accelerator. Unusually it came on the second time I decellerated on the same stretch of road. Guess just like the stop/start all the stars have to be aligned for it to work 😁

sorry to be thick, but having had automatics before, (not VW), I would put it in Drive and that was that.

So you are saying that as the auto gearbox goes through the gears automatically, it changes your display to show the different D positions?

or is this only if you have the driver profile? as someone mentioned sport mode etc

As the DSG box automatically goes through the gears the normal display shows S1, S2etc or D1, 2,3etc. I have only had fluid conventional autos previously so DSG is new to me, but quite happy with it.

It rarely happens to me as well but if you switch to Eco drive profile, coasting happens every time you take your foot off the accelelator.

@tricky2
A workaround i found when i drive in Normal drive profile; When in downhill or straight road, hit the accelerator twice quickly and it will go to coasting. Many Automatic cars have the same.
