Golf R Observations and Questions

Regarding the gear changes, something isn't right mate with your DSG (infamous mech unit )

I can drop 2 or 3 gears with fast paddle flicks without any pause - same using the stick

Hopefully the DSG tune resolves that as it is abnormal

James is referring to the delay when selecting the next lower gear in manual mode, when the DSG has already preselected the next upper gear. There is a delay, it's unavoidable, and is present on every DSG I've driven for an extended period (and that'd be 6 or more).

The DSG needs to anticipate the direction of change you intend to make, before you make it. Say you're in 4th and are decelerating (or even cruising), the alternate shaft may have 3rd preselected, and in those cases, you can instantly shift to 3rd (and as soon as you do, the DSG will anticipate the same situation will occur again and will preselect 2nd on the shaft that originally had 4th engaged, and so on, giving you seamless, fast downshifts).

However, if you're accelerating in 4th (and the DSG has anticipated 5th will be required next and has preselected), and you then downshift whilst accelerating, the DSG will need to pause while the secondary shaft changes from 5th to 3rd. Sometimes you may even feel some hesitation in the power delivery when it finally does shift.

I've seen exactly this behaviour from several VW DSGs, and am confident it's not related to any mechatronic fault.

Good on you, AdamD.
