BMSK ECU (code)Pos 1 · Qty 1Control unit — a genuine BMW part, number 13 61 8 521 661. The number stamped on the part is 13618521661; BMW's catalog files it under the short number 8521661. You will find it on our Air Intake shelf, under Electronic control unit. It supersedes the older numbers 7722909 and 7723394, so a part carrying any of them is the same part.
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 Control unit (13_1117) and Electronic control unit (13_1705). It weighs about 570 g (1.3 lb). It also comes in BMW kits Set, 1-key locking inc. BMSK ECU (code) (8522280) and Set, 1-key locking inc. BMSK ECU (code) (8522284) and 4 more.
We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
