Re: ECU Failure Errors in Flight

That's exactly what it was - it was the waste gate controller actuator. The actuator was replaced and the plane is now back in service - no further problems.

Some of you are having worse symptoms than I am... I'm sorry for that.UTMark wrote: ↑Mon Aug 30, 2021 1:47 pm I’ve run into ECU Failures on takeoff now multiple times. They all ended up being non-latched, but I noticed that it typically has occurred for us on takeoff roll in really hot OATs (last one was last week out of St. George at 41C). I need to get my log files and send them in… which is a challenge because I don’t have a local mechanic with the cables/laptop to do that. Our errors cleared by switching over to the suspected back ECU.
Have you completed MSB E4 029?UTMark wrote: ↑Mon Aug 30, 2021 1:47 pm I’ve run into ECU Failures on takeoff now multiple times.

Thank you for responding. I was referring to the ECU FAIL due to waste gate controller. I did not order RACC in lieu of extra useful load.chili4way wrote: ↑Tue Feb 07, 2023 5:02 pm Gerry, if you're asking about MSB E4 029 that addressed the waste gate controller failure issue (which resulted in an over-boost condition at high power setting and an ECU FAIL notification - but not an ECU failure), the answer is yes. All new Austros come with this required modification.
The DA62 air conditioning (RACC) issues in this thread are unrelated. However, if your DA40NG has RACC, you should open the side/vent windows before performing your "run-up" ECU test when you have the RACC operating.
