So my guess will be that once the computer detects the performance driving style it will signal to disable ASS to maintain its "mode" to not to give the engine too many fluctuations to protect it(hypothetically speaking, from high performance to shut down might not be good for any engines). that was just my guess and I am no expert. But since your case the ASS wont come back which is definitely an issue. Sounds like ur dealer really know what they r doing so i think you r in good hands. happy driving lol.
Gotcha. Dropped it off this morning to look into the ASS not functioning.
Fwiw; it's 57 degrees this morning and I drove in via Comfort mode only. Never gunned it, never manually shifted; drove like a grandma basically because of traffic. Probably 4+ stoplights over 10 miles and it never shut off. Before the M-PPK it would have each time.

I'll report back later today probably...
