I use my ACDP kit for most of my in-circuit MCU programming where it supports it.
In particular I've had zero issues with RH850 processor dashboards. I've done spares for Audi Q2/3 both analogue and virtual cockpit. I've done mileage correction on RH850 based clusters in Crafters.
The reason I prefer the ACDP kit over the Xhorse and other solutions are because there is no soldering required, and even the xhorse adapters though they work are not as easy to align as the ACDP ones. The ACDP adapters have clear alignment on the silkscreening guiding you to the correct position and are much more compact which makes alignment easier, and helps storage in a smaller work van.
I've tried all of the major solutions now and the ACDP kit is the one that comes out first every single time now.

2019 Passat, we used ACDP module 34 to read the R7F701401 cluster data, and added 2 smart keys. It was done in one go and was done perfectly, with plug and play bench adapters.
