That's interesting about the spark plug replacement schedule. I now have a mk7 90..TSI Golf bought new 2 years ago. In June it had its 75,000km service, when the spark plugs were replaced for the first time. I had to wait over a week for the plugs to be supplied as the service centre said they are a different plug from the mk6 90TSI and they still didn't have them. They said mine was the first mk7 to get them replaced. The service which included oil/filter, sump plug, spark plugs and brake fluid change, cost $469. This golf has been the most perfect car I've ever owned too - just can't find a fault in it. Hope it keeps going that way but 75k is a good start.
