Not that im defending these prices and even Porsche @ 10% less sounds expensive to me but all that said, I wonder how much Porsche would charge for this including parts. As I said, an indy wanted about £170 for an hours labour in 2019 and VW wanted if you I recall £114 for supply and fit of the solenoid that locks the fuel flap. This is a £30 part from TPS (original VW) and 10 minutes to fit (this was in 2018). Personally I think any of these labour prices are expensive but then im tight but dont mind paying them the money for a proper hard hours work
...swings and roundabouts.
I gather this was warranty work?
