This weekend I got an ECU B fail annunciation that I was unable to clear while doing my run up. It made me cancel my plans to go to Sun n Fun. I have a 2019 DA40 NG in Savannah, Georgia and have always used SouthTec in North Carolina for my service. I noticed that Southeast Aero services in St. Augustine is listed as a Diamond service Center on the Diamondaircraft website. Does anyone have experience with them? They are 2 hours away by car if I have to drop it off as compared to over 4 hours for Southtec.

The error didn't clear when shutdown and restarted?

No, the ECU B Fail annunciation persisted. Although when it failed the plane was using ECU A, and after shut down and restart it was on ECU B. I'll try it again later today or tomorrow.
