Limited slip diff.unit (exchange unit) — a genuine BMW part, number 33 14 1 203 091. The number stamped on the part is 33141203091; BMW's catalog files it under the short number 1203091. BMW's catalog calls it “Exch-Limited Slip Diff.Unit”. You will find it on our Suspension shelf, under Other Rear Axle parts. BMW has since replaced it with 1206409.

BMW's catalog records no E36 or E46 it is fitted to; it belongs to other BMW models.

BMW draws it on 2 diagrams, among them Differential-Limited Slip Diff.Unit (33_0045) and Differential-Limited Slip Diff.Unit (33_0047). It weighs about 7.2 kg (16 lb).

We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
