We have a 2011 JSW DSG with 6500 or so miles on it. We've noticed a rattle or knock or pinging at start up. It continues it seems till the car is warm. There seems to be no proformance issues. It didn't do it at the 6000 mile check up. The dealer asked what gas station we used and they recommended we change stations. We were using Shell in WI. Now using Exon. We think it maybe injectors, but once it is warm it doesn't make a sound. The nearest dealer is 45 minutes away, which means that it will be warm by the time we get there.
