Another MY10 118TSI Golf (wagon) to add to the list with two cracked pistons. Happened about a week ago about 80km from home and the car was towed straight to the local VW dealer.

Have recently heard back that Head Office will cover 100% of costs of an engine replacement which I'm relieved about. Not sure if I'll hang on to the car, but will see how it behaves with the new engine ... and see how the DSG behaves too.
