Did you do an engine tune before this all started? I remember I got this a couple of times on the dct side after a change on the engine software and it went away once the dct adaptation was reset later. Now I reset the dct every time I try a new tune on the engine.
If your shop did reset the dct and not just reflash it, and you still have the issue, you might have to reflash a regular engine soft to check if it goes away. If successful, then find someone else who does a better job at soft tunes.
