Newbie request: Anyone ever tried to reset Tiptronic memory?

[Claymore]

Hi guys..
Have an 08 model 3.0TDI Sport D3.
I bought it with just over 80k miles on the clock.
A friend suggested that I should have the Tiptronic memory wiped so that it could adapt to my own driving style and journeys rather than anything related to the previous owner and theirs..

Would that make sense?
I know there's probably a way to do it with VCDS, but have read that there is a way to do it manually, by switching on ignition, then holding down the accelerator past kick-down spot for 5+ seconds..
Is it that simple?

Any help appreciated..
