Check oil level light
 

So my 2013 sh-awd is doing this thing at idle (when rpms drop to 0) once the engine gets warm the "check oil level" light flashes in the cluster until i step on the gas again. Super weird issue and the dealer is mystified by the issue. They changed the oil pressure switch because they found it to be faulty only for the issue to be worse after. Anyone deal with a similar issue?

My car does the same, I have changed the oil pressure switch three times already. I pretty much gave up already but it's so annoying, if you find or found any Solution please let me know.
