2012 CC intermittent Low Oil Pressure Engine Off
 

I have a 2012 VW CC I brought to the dealership to fix an oil leak. They replaced the oil pan, serpentine belt and timing chain.
I picked up the car and it was still dripping oil as they apparently didn’t change the gasket. So they did that.

now it is getting intermittent low oil pressure engine off light when car is started in the morning.
I brought it back to them and they say they light is not on and there are no error codes.
They said they tested oil pressure and it was fine.
any ideas or suggestion? Car has 130,000 miles on it.
