Welcome and enjoy you great car mate...
It is a beast and as far as I know it is bullteproof (if you take care of it)...
Go ahead and go the full stage 2+ ... it is totally worth it and will blow you away.... I never expected the car to perform so well... Hell I blow M3's E92 right out of the road
I bought mine stock a couple of moths ago to have it as my daily driver and never ever expected it to be so much fan....
I do not even get my other weekend warrior out of the garage anymore nowadays....
Oh and I absolutely adore the DSG and my new reflash for it....
