Starter broken – complete engine removal?

I drive a 2005 3.0 TDI and unfortunately now the starter seems to be defective. The friendly one claims to replace this part (costs for the part €290,- net allegedly) you have to expand the entire engine block in a 12 hour operation – and then of course install it again. Does any of you know if that’s true? Does this really have to be so expensive? The total cost would amount to a round €2,500,-, which I find pretty crazily… I’m for Thank you for any hint.
