DSG transmissions, especially Volkswagen's, wear out really fast. They are well-known to have issues, and I've personally seen the countless issues myself. They just go through a lot of strain even when they are driven normally; that's just the nature of DSG transmissions. It mimics a manual transmission by utilizing two gear sets (similar to the gear sets in a manual transmission) each with their own electronically-controlled clutch to shift INSANELY fast. They are super fun...only when they are new. I would stay away from them unless you are leasing the car.

The DSG gearbox is a great gearbox, smooth, fast ,but only when it is new. One thing goes wrong with it, and you are screwed. It is a gigantic repair bill for you then!
