This used OEM Audi piston with connecting rod, part number 07C100031EX (also supersedes 07C100031E), is from a 6.0L W12 engine. The piston sits in the left bank of the W12, transferring combustion force to the crankshaft. When the piston rings wear or the rod bearing fails, common symptoms include oil consumption, knocking noise from the cylinder bank, or loss of compression. This is a direct replacement for the original part and must be installed correctly to avoid engine damage.
