This is a genuine BMW brake pedal, part number 35 20 6 752 653. The number stamped on the part is 35206752653; BMW's catalog files it under the short number 6752653. You will find it on our Brakes shelf, under Brake-pedal actuation. It supersedes the older numbers 1163879 and 1163880, so a part carrying any of them is the same part.
It fits every E46 body style (320i, 323i, 325i, 328i, 330i and M3, 1999–2006), with the M52, M54 or S54 engines — and the European-market versions.
BMW draws it on the Pedals/Stop Light Switch (35_0186) diagram. It weighs about 530 g (1.2 lb).
We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
