Golf TSI118 serious issues

As I am sure you are aware the Volkswagen Golf 118 TSI Comfortline Mark VI is a lemon. Mine has had two clutch pack replacements, one Mechatronix Unit replaced, and the engine is now about to be replaced having blown up. It is just 26 months old and has 36,600 km. All these problems are known issues with this car. My dealer told me that they had four vehicles come in on February 5 for engine replacements or repair. They have at any one time 10 or more 118 TSI engines being rebuilt or repaired, my car is one of 15! If one dealer has so many vehicles at any one time being repaired I suspect that thousands of vehicles around the world are blowing up. I believe a major flaw exists with this engine. I have approached the dealership and asked for one of three things to satisfy my concerns: 1. A replacement vehicle (same age and kilometres) like for like with a different engine and gearbox. 2. A fair trade in allowance, or 3. An extension of the warranty to 10 years. All have fallen on deaf ears. I have approached The Department Of Commerce with a written complaint only to be told that whilst the vehicle is under warranty and the dealership completes the warranty work they cannot do anything. As I still have 10 months left of warranty I am ok for now, however what happens after that? I was advised that it would be wise to sell the car before warranty expires, which I have tried to do without success. I cannot get any word from Volkswagen about if they have any solutions to rectify this vehicle and allow me to retain the vehicle for at least 10 years as I normally do with any vehicle I purchase, let alone an acknowledgement that they have a problem with this engine. My question is simply what you would do if you had purchased one of these vehicles and had experienced the issues first hand?
