Tuned ones have a tendency to drop #6. Call any local audi shop and ask them what they think of the EA839.
Edit: Here's some info form 034;
Their tune in particular seems to pop #6.

The EA839 has two variants (3.0L single turbo and the 2.9 twin turbo). The former is found in the 2019 Macan S and pre-facelift (2018-2019) B9 S4/5 and SQ5. Those pre-facelift 3.0L (CWGD GP) models did experience some ring and rocker arm failures. The facelift 3.0L (CWGD GP1) have not. It's the same story with the EA839 2.9L (DECA) found in the early 2018/2019 RS5's...the revised engines in later models, the RS5 facelift (B9.5), and 2020+ Macan GTS models have not experienced the same failures.
