I’ve got the Seat Leon ST FR 184. Same engine as GTD. Golf is slightly bigger in the back due to a squared off rear end. Leon is more sloped. DSG in the 2.0 TDI’s are fine. Early ones were 6 speed wet clutch, later ones are 7 speed wet clutch. All need servicing at 30-40K. The 7 speed dry clutch DQ200 as used in all the lower torque petrols (1.0, 1.2, 1.4, 1.8) and 1.6 diesels are weak. The 1.5 petrol now has the DQ381 as fitted to 2.0 Tsi’s. I have all the specs somewhere. Our old Fabia 1.2 Tsi had the DQ200. It was never right from day one. Great car and engine but clutch was like a switch on or off.
