What I won't do for you guys! Both openings in the thrust plate expose drain plugs--front sump and rear. The rear also exposes the oil sender connection. The drain plugs are very small with recessed hex wrench openings.
"The E92 M3, just like the E46 M3, is equipped with a reinforcement plate, known as the thrust panel, made from aluminium alloy. The thrust panel primarily increases the torsional strength while also acting as a lower motor cover and oil pan protection. The thrust panel is fitted to the axle carrier with six bolts from below, and has two openings for changing the oil."
