What's causing my SEAT Altea judder at low speeds?

I own a 2009 Seat Altea 1.9 diesel, with a DSG gearbox. Recently the car has started to judder at low speeds. Can you tell me what’s causing this and how I can fix it?
When did you last change the transmission fluid and microfilter? This needs to be done every three years.
