This is a genuine BMW bracket f electric change-over valve, part number 18 10 7 513 300. The number stamped on the part is 18107513300; BMW's catalog files it under the short number 7513300. You will find it on our Exhaust shelf, under Catalytic converter/front silencer. It supersedes the older number 7502475, so a part carrying that number is the same part.
It fits the E46 sedan, coupe, convertible and touring (325i and 330i, 2001–2006), with the M54 or M56 engines.
BMW draws it on 2 diagrams, among them Vacuum control, exhaust flap (18_0428) and Vacuum control, exhaust flap (18_0524). It weighs about 90 g (0.2 lb).
We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
