I've just gone straight from HN+DAB_K0097 to HN+R_EU_AU_K0900 with a modified firmware pack that's Bose safe on my 2011 A8 (Without Bose might i add).
Mines the 3GP with the HDD, not sure if they all are on the D4 A8?
I followed a great guide by congo on the A5OC forum
It took 1h10m, 13 updates, no errors, and all works fine (i used a SanDisk Ultra SDXC Memory Card 32GB 80MB/s Class 10 UHS-I)
Haven't plugged VCDS in yet, i'll pluck up the courage to do the MAP, then have a go at clearing any faults.
