It highly depends in which state (Bundesland) you live. The most states have don't have those fees anymore, only 3 of 16 states have them as far as I know. The height of those fees is about 500 € per half-year.
Independent to those fees (which are called Studiengebühr) there are other fees which have to be paid in all universities: It is called "Semesterbeitrag" and is about 150 € per half-year (average guessed on my experience ;-) ). It is used to pay public-transport and such stuff.
