VWSA recommends putting the 'box in sport mode when in traffic to save your clutch pack. There is a service bulletin out for it. We had a clutch pack start failing in a 1.4 TSi at around 40k km. There is a known issue with the 1.4 TSi and DSG combo across the whole VAG range in the earlier iterations of DSG. VW tried to tell us that the climate here kills the things, they don't have this issue in other markets. I would strongly recommend extending the service/warrenty plan as long as you can. It wasn't that expensive to do for us compared to what a clutch pack, mecha unit or turbo replacement costs. We now have a 2016 1.4TSi Jetta 6 in the home fleet and it seems to be behaving a bit better than the 2011 Jetta 5. The DSG system is definately alot more stable. We also all know to put it in sports mode in traffic now, it hurts the fuel consumption figures though.
