This is my only dealership experience except for when the 2012 Panamera almost grenaded from the cam-adjuster bolts a few years ago. I don't count that one.
I'd been looking for a 2019-2021 Macan with some kind of v6 for a bit. Dealerships, marketplace, whatever.
Finally settled on this 2020 turbo on Autotrader. PO is an enthusiast and obviously interested and meticulous and had amazing records there's some CPO left and I bought his vibe as much as the car. Great Car, great guy yadda yadda.
Right on the way home upon wailing on the car I experienced a few errors that made me anxious but not terribly so.
I decided to go to the dealer because why not? See what they say and I'm still all precious about the new-to-me car.
I arrived with a list of the codes I had read from the car. Evap system error, turbo underboost, and "brake fluid fault". (all vacuum-adjacent errors yeah)
Anyway the tech smoked the vacuum system and found a teeny-tiny vacuum cap that had been chewed on by a mouse! Tiny hole the size of a ballpoint. He also found a crack in a (very accessible) vacuum line right up top in front of the turbos. Mouse here too. I believe him.
Anyway the 1.5 hour diagnosis and video at $295/hr was $442.50 and shop supplies were about $50 for a total just under $500 with repair declined.
The estimate to replace the single vacuum line was $283.34 for the part and $2306.90 for the labor for a total of
$2590.24
Just data points, I don't really have a shareable opinion but I had an interesting experience and thought you may enjoy the numbers.
PS god bless that video and the pelicans who gave me a little advice and the $127 part that any VWAG dealer might have sold me if I had wanted to fix it in about 20 minutes myself which i'm not saying i did but i might have but i'm not saying i fixed it myself
