What is the average cost of replacing a Tiptronic switch?

What is your question?

I brought my car into the dealer because of a hesitation while accelerating (going up hills or merging onto the highway) otherwise it drove fine. VW is saying that I need to replace the tiptronic switch (by replacing the entire shift assembly) quoting over $2000 - and now 1 day after leaving it with the dealer it is stuck in 1st gear and will not let me remove the key while in park. This all seems crazy to me, is this a normal price?
