What's Included

Genuine BMW part 33 13 1 213 997: Lock Ring. The number stamped on the part is 33131213997; BMW's catalog files it under the short number 1213997. You will find it on our Suspension shelf, under Other Rear Axle parts.

It fits the E46 sedan, coupe, convertible and touring (330d, 1999–2005), with the M57 or M57N engines.

BMW draws it on 45 diagrams, among them Differential-Drive/Output (33_1021) and Mechanical limited slip differential (03_1127). BMW's catalog calls for two of these at each place it is fitted. It also comes in BMW kits Gasket Set Differential (7568368) and Gasket Set Differential (7568368) and 2 more.
