Accumulator — a genuine BMW part, number 84 21 9 416 457. The number stamped on the part is 84219416457; BMW's catalog files it under the short number 9416457. You will find it on our Instruments & Electronics shelf, under Other Communication systems parts. BMW has since replaced it with 0397834.
It fits every E46 body style (320i, 323i, 325i and 328i, 1999–2006), with the M52, M54 or M56 engines — and the European-market versions.
BMW draws it on the Mobile telephone Siemens S10 (84_0205) diagram. It weighs about 66 g (0.1 lb).
