Compression spring, third brake light — a genuine BMW part, number 63 25 6 900 698. The number stamped on the part is 63256900698; BMW's catalog files it under the short number 6900698. You will find it on our Lighting shelf, under Flash signalling light (authorities).
It fits the E46 convertible (323i, 325i, 330i and M3, 2000–2006), with the M52, M54 or S54 engines — and the European-market versions.
BMW draws it on 2 diagrams, among them Third stoplamp (63_0618) and Third stoplamp (63_1055). BMW's catalog calls for three of these at each place it is fitted.
We have not had one on the shelf yet. Request it and we will tell you when one comes off a car.
