I've gone from 1.4tsi 7 speed dry clutch to 1.8tsi 7 speed dry clutch. One thing I've noticed is that when coasting in ECO mode it often disengages and selects a low gear (3 or 4). I don't remember this happening in the 1.4

 

If when it disengages I tap the accelerator again - it will go back into ECO mode and then stay there. Is this just a case of a bigger engine needing to rev higher until I override by tapping accelerator again?

I've made a similar change from a 1.4TSI to a 1.8TSI and observed the 1.8 coming out of ECO mode - but it's under situations where engine braking is required rather than just coasting , such as going down an incline (not even a hill).

Why would the car need to break if you haven't asked it to?

I've no idea why the car would need to break; If the slope is such that you are trying to maintain constant velocity but the car is picking up speed due to gravity, then it may need to brake.

When I used to use ECO, mine never came out of coasting mode going downhill and I had to shift to lower gears manually to take advantage of enging braking.

I'm a little confused about what the discussion is. I thought one of the features of eco mode is the coasting. Are there some cars that don't do it? 

My 2.0tsi will just keep coasting, unless I press the brake. Then I have the put some throttle on and come off the throttle for it to coast again.

 

Only time it auto drops into gear is if I go slow, 15mph ish. I'm not sure what exactly triggers it, but if I coast into my road and turn 90deg into the last bit of road, it goes into gear. 

I don't know if thats low speed, sharp steering or what does it.

My 1.8 coasts but disengages at much higher speeds than my 1.4 used to disengage at - but then reengages and stays engaged if I just tap the accelerator again

 

So it can coast in ECO at the lower speed but it's a two step process
