We've had 3 DSG cars between us - no problems so far. Mind you, they were under warranty and we get them regularly serviced.
My current car is a 1l 3-cylinder DSG Kamiq - which I am pretty happy with. Only complaint being the slow starting touch screen and the move away from physical buttons (e.g. for heated windscreen).
They're unreliable where I'm from.
Otherwise, they make fabulous desirable cars.
