DA62 following manual checklist doesn’t start right engine since last beta-update. Both start engine buttons only start the left engine now. Right engine can only be started via automated quick-start-up.
Personal note: As a regular DA62 pilot, I know the system and checklists inside out. Since the last beta patch ( https://forums.flightsimulator.com/t/release-notes-su6-beta-1-8-11-0-august-5-2026/772691 ) and the fix “Fixed alternators and battery flickering and using a starter”, the right engine isn’t starting manually anymore. It seems like it’s connected to the left engine somehow. When starting at night, you can see the light flickering. Alternators are both on and ECU on auto.
FREQUENCY OF ISSUE
How often does this occur for you (Example: Just once, every time on sim load, intermittently)?
Every time, it was only in beta, but it’s in SU6 now.
REPRODUCTION STEPS
Please list clear steps you took in order to help our test team reproduce the same issue:
Select any airport and a parking spot for cold start
Follow the manual startup routine (e.g. checklist)
Try to start the right engine, G1000 and lights will flicker and the left engine is starting instead (only if not running already)
If the issue still occurs with no mods and add-ons, please continue to report your issue. If not, please move this post to the User Support Hub.
What peripherals are you using, if relevant:
Playstation 5 (beta & SU6)
MEDIA
Adding a screenshot of the start button isn’t adding a lot of value. Video can’t be uploaded due to size constraints, but it’s really easy to reproduce.
I am also experiencing exact same issue in live SU6 version. Right engine starter starts left engine if you shutoff left engine. Right engine starter doesn’t even turn right engine over. Right engine starter seems to be linked to left engine start since SU6.
Description of the issue: Attempting to start up either engine using the proper procedures results in the avionics cycling power and the engines not starting upon pressing the “START RIGHT/LEFT” button.

REPRODUCTION STEPS
Please list clear steps you took in order to help our test team reproduce the same issue:
Spawn cold & dark in any variant/livery of the Diamond DA62
ELECT MASTER > ON
RIGHT ENGINE MASTER > ON
RIGHT ENGINE START RIGHT > [PUSH]
Observe G1000 screens briefly power off and boot back up and right engine does not start
Repeat steps 3 and 4 with the left engine

In continuing to troubleshoot this issue I’ve noticed some really bizarre variation in how the aircraft is broken during startup. I’ve had some restarts of the flight where the right engine start button will start the left engine, but so will the left engine start button, so there’s no way to fire up the right engine. Others where neither start button does anything but recycle the avionics (as described in the original report).
Seems like a lot is wrong with this one after Sim Update 6 unfortunately.
It sounds like a corrupt file. Perhaps try deleting the DA62 files in the sim (not sure if you can uninstall in the Content manager) then restart which should force a re-download of the file.
Reinstall didn’t solve anything. Still same behaviour, right engine button starts only left engine. G1000 still flickering, like the result of a power surge.
Updated description and also linked the additional G1000 details.
I was an early responder to this thread having just shutdown th sim after a successful DA62 flight.
This morning on trying to continue my tour I’ve run into exactly the same problem. As the DA62 is streamed I cannot change anything with installed files and Content Manager similarly won’t let me do anything.
I’m on PS5 and it’s R1 + down arrow (dpad) for me, but the feature is called “Auto Start Engine”. It’s a work around, so I do the cold start as far as possible and my last step is to trigger the auto start to get the right one rolling. But I hate this key combo…
