Is it something official, cause ive never heard of a dealer say this
Just to add a little more. I found the procedure on here, its documented several times if a search is done but...... I came across a comment from "Logger" that appeared to cast doubt on it. So I decided to conduct a few of tests.
As above the DSG 7 Speed Mechatronic Control Unit is always adjusting to your driving patterns long and short term.
I drive in urban traffic crawl 80% of use of the car in any given week. ie, average journey time is 15 to 20 mins, distance is 6 to 8 miles and average speed is 20mph with a road speed limit at 30mph.
At junctions, the throttle didn't respond on setting off, press, nothing for about 0.25 seconds, reaction was to press more and the engine spun into life, as did the wheels! Gear changes from 1st to 2nd were always a bit lurchy as were some higher ratios if accelerating at mid throttle settings.
So with that in mind I first of all changed my driving habits, ie. instead of casually driving along with very light throttle all the time, I drove more agreessively on the throttle, chose faster routes. Did this for two weeks. Effect: Nothing
Next, drove the set-up sequence above without the throttle/no ignition action. Did it twice two weeks apart and assessed for two weeks each time. Effect: Nothing
Then did the throttle/no ignition for 20 seconds action and immediately drove the set-up sequence I wrote above in the following 10 minutes. Effect: Result!
The engine immediately responded to pressing the throttle when setting off at junctions. It felt connected directly to what I was doing with my right foot. The 1st to 2nd gear change happened smoothly, all other gear changes cannot be detected, even under fairly hard acceleration. Releasing the foot brake, the gearbox immediately enages "creep" (5 - 6mph) mode whereas it used to think for a second before enaging the clutches.
I cannot find anything official on the web WWW about this. If someone has a copy of the VW's ELSA workshop programme dated post-2007 edition (mine only goes to 2003), what does it state about conducting a "Basic Setting" sequence on the 7 speed DSG in the gearbox section of the maintenance manual?
The 6 speed DSG "Basic Settings" is well documented on the Ross-Tech VAGCOM web site and in that case, it is necessary to use the car's diagnostics with something like VAGCOM. I borrowed the drive sequence from there as on here from what I could find, there was only mention of pressing the throttle but no after set-up process of learning for the Mechatronic Control Unit.
This is the 6 speed drive learning sequence documented by Ross-Tech Wiki (VW Golf/Jetta/Bora (1K/5M)) after using VAGCOM to reset values in several parts of the 6 speed DSG:
"Defined Test Drive
Suggested test drive after replacing the mechatronic or successful basic setting:
ATF Temperature 30...100 °C (86...210 °F).
Drive in Tiptronic Mode from stand still up to 6th Gear.
While doing that make sure to drive in Gears 3 or 5 for approx. 5 minutes and also in 4 or 6 for approx. 5 minutes.
The engine speed window for all gears is 1200 - 3500 RPM (for clutch calibration).
Perform one sharp braking followed by a full throttle acceleration (oil return check).
Evaluate creep and starting-off points."
