We had this too. The earth to one of the px sensors had failed
(airbox I think) in the TCU multi pin plug and was causing the TCU to
motor the wastegate fully open. You should be able to troubleshoot it
by using the rotax TCU program and a multi meter. We spliced in a new
earth at the sensor and it has run fine ever since.
