Don't know for sure but I always assumed it was for a sensor that was used on other cars with that sump, oil temp or something.

Iv never seen any psa sump with a sensor located there though. I dunno. Possibly the designer dropped a bollock and realised he could only drain half the oil so added a lower one as a last ditch attempt . Tbf the blank for a sensor explanation seems more viable though.

so you can pick which angle to drain your oil at . . .

I think there is a set volume of oil left if you have the car perfectly flat (ie on a ramp) and drain from the top one too.

Might be a mad suggestion but, is it a breather plug?

I always take the filler cap of for a breather when i drain one out
