Had an Audi, did the work myself. Audi parts are not VW parts just like Porsche parts are not Audi parts! I think a relay or a few hoses were shared across the car companies but nothing to write home about.. Second Audi’s are heavier than their VW counterpart so they needed stronger equipment. Made and shipped from Europe. Third, Audi had a tighter build process so a lot more work had to be done before a similar task on a VW (timing belt comes to mind). The same exists for Lexus/Toyota, Ford/Lincoln, Nissan/Infiniti. What I’m saying is your nice house may cost 2x because your nice house has nice things that increase labor costs. Just like that upsized vehicle manufacturer..
