Have the oil sensor light coming up on the dashboard.
No oil leak, no oil usage, plenty of oil in there and is not the pressure warning light.
Gotta drive 500kms home tommorow as I'm out on sight, but it should be ok, right? I'm thinking the sensor has just become knocked out of position/pin broken when I brushed the bottom of the car on some dirt/stones (no sump damage, checked) and as it is in the sump.
So yeah, not to worried as it seems a pretty minor issue, but something I wouldn't mind putting my mind at ease over.
