My trad Plus8 has Gems management. There are two oil pressure sensors. One for the dash gauge, the other linked to the ecu. If that ecu one detects low pressure then it cuts the engine to protect it.
The gauge one failed on mine causing variable gauge readings. No effect on engine cut out but was a bit worrying at first. I realised the ecu one was working so changed the faulty one asap. Straight forward screw in with two wires. Been good since.
Last year the sump gasket was changed as it showed signs of weeping. Spotted one drip on the cardboard I put under the car ( leak detector system!).
As for ecu/computer glitches, I tend to let the system boot up fully before starting. Let it do its normal system start checks. On the Kia ( 1 year old) the display screen went odd a few weeks ago. Not an issue and it returned to normal after switching off/on. Basically a simple reboot as you can do with any pc/tablet/smartphone. It’s also worth checking wiring connectors for good fit.
