Default Brake Servo Replacement 4.2tdi

Hi folks
Anyone had this done. I've got an issue where the brake boost isn't working following engine start up. First noticed it in a car park, and yesterday on the driveway. As soon as I'm off and moving everything is fine. Local indie had car today and says vacuum draw and pressure seem okay although they dont have data for a 2010 engine so basing it off other cars.... but the servo is slow to react and they suggest as point one needs replacing. Quoting £1500 as a starting point saying upper limit unknown as multiple parts including both calipers may need replacing following brake bleeding and strip down as they are prone to damage.
