Could be a coil pack or spark plug issue. I would get it checked at your dealership if it doesn't feel right. Have you run VAG-COM to check for any error codes?

They will want to know. The car doesn't feel as it did and it misfired at high revs when warm...they need to check it. There are many fault codes that appear on VAG-COM without any hint of a warning light on the dash.
