in typical porsche mechanic fashion, my estimates have a pretty broad range. annoying, but it is, what it is. without disparaging other local los angeles mechanics, I will say that Dutch Treat quoted 1 hour to replace it. kinda makes me feel like some of those other mechanics that I'm not disparaging either like to charge way too many hours or just charge people to learn how to work on their cars.
2 thumbs up for dutch treat.
the part was only $40.
