Other Communication systems parts — a genuine BMW part, number 84 21 0 300 310. The number stamped on the part is 84210300310; BMW's catalog files it under the short number 0300310. BMW's catalog gives it no English name, so it is listed here by where it sits. You will find it on our Instruments & Electronics shelf, under Other Communication systems parts.
It fits the E46 sedan, coupe, convertible and touring (320i, 323i, 325i, 328i, 330i and M3, 1999–2006), with the M52, M54, M56 or S54 engines — and the European-market versions.
