At times when coasting or at a stop, it will shift to neutral. Sometimes you can surprise it and the re-engage is rather abrupt. (Mine seems to have learned my driving style and seems to run just fine.)

If that's not what you're experiencing, I'd be concerned.

Sorry, I just noticed that this is in the 1.8L section. I have no idea about that engine. I've got the 1.4T.
