02 View BMW DiagramSee this part on the official exploded view→Genuine BMW part 12 90 7 534 921: Bottom part, E-Box. The number stamped on the part is 12907534921; BMW's catalog files it under the short number 7534921. You will find it on our Electrical shelf, under Other Engine Electrical System parts. It supersedes the older numbers 7521578 and 7521579, so a part carrying any of them is the same part.
It fits every E46 body style (320i, 323i and 325i, 1999–2006), with the M52, M54 or M56 engines — and the European-market versions.
BMW draws it on 4 diagrams, among them Control unit box (12_0899) and Control unit box (12_1140). It weighs about 630 g (1.4 lb).
We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
