A plea to one of the Pros on deck.
 

The Evaporator is being replaced in my 93 500e
Since Winn is paying the 25 hrs to remove the Dash, is another 2 (Book labor) really chargable(to me) to do the 6 vacuum elements, or should I cry foul and ask for the labor to be cut in half??? And does the "Book" call for 2 hrs to replace the expansion valve??

I don't know if the dealer book time differs from the crashbook/software (Mitchell). It looks as if the time to R&R is .9, however that does not include time to evacuate the system and recharge which takes an addtional 1.4.
