Sensors not same on my 328iX - different lengths + the little donuts attached to them in various places for attachment points are not same & they are in different positions along the length.
Mebbe they just messed up and threw in 2 of the same by mistake.
As you already found, they are 2 different P/N - there is a reason for that
Now whether they will still work can only be tested by installing...
