I believe there are a couple newer revisions than that. Try going to the massive A8 shudder thread and poking around in there.The answer should be found there.

August 19 2020 TSB 18-NA -355 was the latest / update that I could find. I took copy on my iPhone to dealer when I had Triple Flush done on my 17 GS last month. Showed them copy and had no problems with dealer doing Triple Flush under BTB warranty. My GS had no symptoms and I told them I wanted it done.

Lot's of bad information on the forum about this TSB. That TSB was revised March 30, 2020. Here is the latest (attached).
Seems some people don't look at the calendar.
