Re:Oil light on at start up but not always
2 cents in: I don't know about the Breva/Griso/Norge ,but I imagine they are all they same. In the Stelvio parts break the sensor looks like a pressure transducer I would replace it first, and check the connection at it. Press. transducers even on 10 million dollar helicopters are cheap crap that fail all the time and sometimes start to do unexplainable things for no apparent reason. Start with the simplest, cheapest thing first.
