I was flying today and had an oil pressure alarm in the -12. Dynon alarm went off and oil pressure was zero. I was over a local field at 2,000 and did a precautionary landing at idle. Oil temp did not increase. On the ground there was lots of oil in the sump. I had been aloft for about 30 minutes. I burped the engine and there was the same quantity that I left with. No engine oil in the engine compartment and everything was in place and dry. electrical connections were heat srinked and solid. I started it again and had oil pressure but the engine stopped because I didn't have enough throttle open. Restarted and zero oil pressure and shut down. I got a ride home from a local A&P friend. Nobody around knows anything about rotax engines so the next step is completely unknown. I called van's and the help desk line was busy and went to the operator and then they were closed.
Any long time rotax users have any ideas? It seems to me that when the engine burps that the engine driven pump must be working working. So a sender issue? Very disappointing for a 12 hr old engine.
I will be calling van's in the am but I don't think they have much experience with this engine past the design phase. Raises big questions about sophisticated electronic systems without a wiring diagram.
