Rottenjohn is right.....
Ive spoken to our old engineer, if getting Gong's in flight but no warnings on the VEMD/CWP , could be water in the system.
But if you get Gong's in flight , almost 99% a red warning would of appeared on the VEMD/CWP
If you lost the oil from the engine, there would be low pressure Gong / High Temperature Gong going off.
The Ec120 is a very good machine, you do get the odd gremlin from time to time (generally electrical)
The fact you landed (I assume ASAP) whats the problem ?, unless you continued on after the audible gong's went off could be an issue
Its hard to give a definitive answer, with all the posts above mine, you have a general idea now
