basic setting will reset the clutch kiss point and make it sharper, this is done via vas or vcds but it may also highlight a worn clutch pack
the delay should be milliseconds and unnoticed
Drive-away
When starting from a stop, the clutch is controlled
according to engine speed. Depending on the driveaway
characteristic, the gearbox control unit
computes an engine nominal speed which is set
via the clutch torque.
The driver input as well as the torque curve of
the various engine variants define the drive-away
characteristic.
Power flow transition (overlap)
The gearshift involves two functions:
1. Engagement of gears in part-gearbox 1
and/or part-gearbox 2 by means of hydraulically
actuated shift forks.
2. Power flow transition between part-gearbox 1
and part-gearbox 2 by means of clutches K1
and K2
The power flow transition (first to sixth gear) is
implemented by means of so-called overlapping
shifting between clutches K1 and K2. This means
that, during the power flow transition, the powertransmitting
clutch (K1 in this example) remains
capable of transmitting torque at a reduced
pressure until the engine torque is transmitted
to the engaging clutch (K2 in this example).
The gearshift is assisted by a temporary
reduction in engine torque during upshifts
(refer to illustration), or by a temporary increase
in engine torque during downshifts.
When starting from a stop at a low throttle position
(e.g. 60 %), engine speed is increased at a low level
up to the next clutch engagement point.
When starting from a stop at a high throttle position
(e.g. 100 %), the engine speed is increased at a
higher level up to the clutch engagement point.
but without going to deep i would suggest the oil and filter is changed followed by the basic setting test drive to ensure good maintenance as this will do no harm and may resolve your issue
consider this but need full details ie engine code and year
A3 2.0TDI with 6 speed DSG gearbox:
- poor accelerator response
- delayed power transmission
- erratic acceleration
- jerky gear changes
During the test drive it appears that the power is suddenly transmitted one or two seconds after accelerating.
Technical background
The pulling away clutch of the DSG closes when the brakes are released and is therefore under load. The delayed power transmission is caused by a late and then sudden boost pressure build-up.
Visual check of the turbo charger. Make sure that the stud with clamp nut is on the turbo charger.
If the stud or clamp nut is missing, replace the turbo charger
I advise basic setting suggestion and oil and filter change, if you read the description below it will make some sense
Clutch control adaptation
Comfortable clutch operation must be maintained
in all operating states and throughout the useful life
of the clutch.
For this purpose, the relationship between clutch
valve control current and clutch torque is subject to
continuous updating.
This process of updating is necessary since the
friction coefficients of the clutches are continuously
variable.
The coefficient of friction is dependent on the
following continuously variable factors:
– ATF (quality, ageing, wear)
– Oil temperature
– Clutch temperature
– Clutch slip
To compensate for these influences, the
relationship between control current and
clutch torque is determined in various
driving conditions, e.g. under microslip,
and stored.
in doing this you delete the learnt values and return the values to new but this should only be done when either the mechatronics or clutch pack is replaced but it can be done to fine tune but it can cause premature ageing of the clutch wear index
you are now more informed than your article you read hopefully
