    had a simillar problem which turned out to be a injector fault. can easily be checked by vag-com to check the missfire on cyclinder 2 then swap injector from a working cyclinder to see if the missfire in that cyclinder is fixed, note that it is advised to change the injector seals top and bottom if they are removed. good luck with your problem:greyrs4:
