Hi Guys, there is an ECU update, mines been done (2 weeks ago) as they were trying to rectify an issue with the DSG making a clicking/ticking noise when engaging in lower gears up and down. - to cut a long story short it did nothing to help the dsg noise. The computer seems more responsive and the digital speedo more accurate (changes more in line with the needle i.e not lagging as much) Other than that cant comment further. VW australia told me there are 2 updates, one for the transmission and one for the engine but i don't know anything else.
Hope this helps
