Problem:

When attempting to read the encrypted BCM on a 2011 Porsche Cayenne using Yanhua ACDP2 with Module 10, the device displayed a “Read chip data error”. After disassembling and reinstalling the interface board, I tested the setup on an iPhone, a computer, and a Samsung device. While P-Flash reading worked without issue, an error prompt appeared whenever I tried to read D-Flash.
