After all these years. That car still looks great.
If I didn’t have my Cayenne Turbo S I’d have a S8. Loved my wifes D3 A8 and the S8 is better overall of course. I know the later D3’s with the rear timing chains need the oil changed regularly to keep the chain guides clean and to reduce wear along with clean oil in the tensioners. Which version of the
Cayenne Turbo S is a great choice! It was on my radar as a candidate for my next vehicle when I decided to retire my B5 S4 to the weekends. It seems like many people go from B5 to the Cayenne Turbo S. Ultimately I found the 2007 D3 S8 and am so happy I did! I am unsure of the timeline for when Audi started implementing fixes/material improvements from the factory floor on the rear chain guides and tensioners. I know from firsthand experience of a 2008 3.2 A6 that had failed upper timing chain tensioners.
It would be interesting to crosscheck the part #'s between the B7 & B8 S4’s compared to the later D3 A8’s as the B8’s definitely had a better reliability with the timing chain & adjusters/guides. I know they say long interval oil changes and lower grade oils have a lot to do with it. You want clean oil and good lubricity to extend their lives.
