This is a genuine BMW hex nut, part number 23 01 7 530 415. The number stamped on the part is 23017530415; BMW's catalog files it under the short number 7530415. You will find it on our Transmission shelf, under Other Manual gearbox parts.
It fits every E46 body style (325i and 330i, 2001–2006), with the M54 engine — and the European-market versions.
BMW draws it on the Manual gearbox GS6S37BZ (SMG) (23_0928) diagram. BMW's catalog calls for two of these at each place it is fitted. It weighs about 5 g (under 0.1 lb).
