Water Pump Replacement VW Sharan TDI (AC Removal?)

Hello everyone!
I recently bought a SHARAN TDI (with a 1Z engine) for my loved one. Unfortunately, the water pump failed the very next day.
When I picked up the car from the BOSCH service center, I was presented with a bill for €306!
I was told that parts of the air conditioning system had to be removed.
My question is: was this really necessary, or is the workshop just trying to make more money?
I'm asking because the same workshop previously performed 'repairs' on a friend's car that weren't actually necessary.
Perhaps someone here is familiar with the Volkswagen Sharan and can help me.
Sure, no problem! Here's the translation:

'Thank you in advance!'

Hello,

If I remember correctly, you need to disconnect the compressor for that. But that's a job that takes about 5 minutes.

To the best of my knowledge, you need to do the following:
- Remove and install covers.
- Drain and refill the coolant.
- Install and remove the V-ribbed belt.
- Remove and reinstall the compressor (this can be done without any other work on the refrigeration circuit).
- Remove and reinstall the headlight.
- Remove and reinstall one engine mount.
