Since you're presumably outside of warranty and your dealer is rather far away, I'd try the following:
First, I'd try this:

Second, I'd do a transmission fluid change. It's very easy and rather inexpensive. You'll just need 3 quarts of a good synthetic 75W-90 GL-4 gear oil and about 30 minutes of time.
If may or may not help, but it's easy and inexpensive. Worst case would be that you need the new updated 2009-spec clutch plate, but definitely try the above two procedures first.
