VW's advice to you is rubbish, they sell the Golf in this country and they are responsible to make sure it is suitable for the climate we have. I wouldn't accept this advice. As for the new model I can't say, but I doubt there has been any change.
Normally a front-wheel drive car will wear out the front tyres twice as fast as the rears, and the idea of rotating the tyres is that you spread the wear out evenly across all four tyres and that way you end up with the better tyres on the front, which does more work in terms of braking and steering.
The problem is that no one can tell you what is fair wear and tear; there is no benchmark that determines what the life of the brakes should be. In the “good old days” when we all drove around in cars with drum brakes it was relatively simple, the brakes would last a long time and no one worried about brake wear, although the brakes were often so poor in those old cars it was hard to tell when the brakes were worn out. VW is correct in saying brakes are made of different materials today to get the braking performance we want, and as a result they wear out faster. Your experience is not unusual, it happens on a lot of cars, particularly those from Europe. I doubt you will have any success claiming against the warranty; your best course of action is to seek legal advice and perhaps claim the car has not performed to your expectations, and VW has not lived up to its end of the bargain when they sold you the car.
Pistons can melt for a number of reasons, but essentially it’s because the piston is getting too hot. It could be because of pre-ignition, a lack of cooling for the piston itself as it was for the Nissan Patrol turbo diesel when it was melting pistons, or it could be something else. That they are only changing the pistons isn’t necessarily an issue, it really depends on the pistons they use. If it were correct that they are having problems and are getting pistons from Germany I would hope that they have made a change to the piston design that would correct the problem. If they are simply replacing the pistons with ones that are the same as those that failed then you could reasonably expect to have them fail again. I would demand to know exactly what they are doing in the rebuild, so you know everything they do and you can make a proper assessment. It wouldn’t be a surprise to me if they installed a recalibration in the engine computer to alter the ignition settings.
No doubt you could do it yourself, but most owners couldn't and the warranty is a general document written to cover all owners. Trying to come to a different arrangement with an individual owner makes life complicated for the carmaker and I can understand why they won't do it.
I would be very cautious with any Golf right now, VW has owned up to problems with the 118TSi engine that result in blown pistons due to pre-ignition. While I’m guessing your car doesn’t have a 118TSi I wouldn’t be experimenting with lower grades of fuel in any VW engine until the full extent of the issue is known. Use a 98 octane fuel.
VW has issued an alert to dealers and owners about a problem with the engine electronics of the TSI engine, advising owners not to drive their cars if they are experiencing any misfiring. Owners who are should report their problems to their dealers who can reset the engine's knock sensors to fix the problem. If it's not addressed VW says it could cause damage to the engine, as it seems could be the case with yours. So ask the dealer to show you what has been done to ensure the problem won't occur again. Other Golf owners with this engine should contact their dealers and ask about having the change done on their cars.
Check the PCV valve, it might need replacing. A faulty PCV valve can cause a problem like you are describing.
