What’s the verdict on the correct size? M12x1.5? I’m about to order one online but I’m getting mixed information.
I can't answer your question directly. Since I'm seeing a different size than you have in mind.. I'll let you decide. But I have two links below. One showing the OEM part number, the other selling and describing the oil drain plug.
First link.. see part # 14 on the 'oil pump' schematic for OEM part number.

Second link is the OEM part showing size (5M x 1)
