I received a letter from VW this morning about the DSG:
Some customers have reported transmission issues. Due to a potentially faulty component, a bushing which can suffer premature wear. They go on to say that this will cause the transmission to be very jerky but does not affect safety. This applies to some ( "a limited number") of DSGs in the 2007-2009 range.
So they go one to say that by late spring they'll have a tool that can detect transmissions that have the faulty bushing. If you have one you'll get a new DSG and a loaner while they do it.
The warranty on the transmission is extended to 10 years/160,000 km. I read this as the warranty being extended on all DSGs in the range where there MIGHT be a faulty part even if a particular transmission in the range is not faulty.
They don't say how many transmissions may be affected. I bet that a batch of these bushings with improper heat treatment or slightly off spec for size got mixed in with some good batches so they don't know just how many are bad.
