Ive heard on the A3 (8P) you can set the steering wheel via vag-com so it become lighter,any one know how to do this?

I fitted 18'' s-line wheels,lowered the car 25mm,fitted new track rod ends it was ok,then i had 4 wheel alignment done and now steering is slightly heavier,tracking was out (obviously after new track ends and lowering) is it quite normal to go heavier,its not very heavy but you can tell,ive checked tyre pressures they ok.

If any one can guide me how to adjust steering through vag-com to set it so its lighter please let me know thanks.
