Just throwing my story in, went for service yesterday at Osborne Park VW on a 2010 Golf 118TSi with 63,000km's. I told them at service it was sometimes idling rough at startup. When I picked it up they told me timing chain had stretched, and they'll replace it and tensioner next week under goodwill, no charges at all. Also had airbag replaced. As far as dealerships go they're pretty good, always look after me, no complaints.
