This is a genuine BMW exchange control unit ABS, part number 34 52 0 026 619. The number stamped on the part is 34520026619; BMW's catalog files it under the short number 0026619. You will find it on our Brakes shelf, under Electronic components. It supersedes the older number 1162646, so a part carrying that number is the same part.
It fits the E36 sedan, coupe, convertible and compact (318i, 320i and 325i, 1992–1999), with the M40, M42, M43 or M50 engines — and the European-market versions.
BMW draws it on 2 diagrams, among them Hydro unit ABS/ASC/control unit/support (34_0382) and ABS hydro unit/control unit/support (34_0877). It weighs about 725 g (1.6 lb).
